yeah okay so uh first i'm allowed lame uh um
00:00:05
whatever they i'm and we sent to obtain a scathing is one uh which is a is
00:00:11
a centre for computer science and electrical engineering and i'm assistant professor that would be the
00:00:15
sales department in in technique or is it in this was also an mm um basically
00:00:22
i i was challenge if we can use this word to talk about children speed
00:00:29
and and i couldn't say no so we have someone
00:00:34
to blame about and and an and basically what
00:00:38
the the i. b. uh about uh whether these things of the uh to the space how
00:00:44
speech along what's is that open how children acquire this speed on
00:00:49
what they're the typical things that might go wrong and and
00:00:53
with apologies i'm finally about how we can
00:00:58
what what versus the speech and and and and this this is quite um i'm the shoes
00:01:03
ah especially because most of the first things are related with probably sick
00:01:08
sick linguistics all and losses and clinician produces understood telling us pathologies
00:01:14
uh s. o. and the reels that are are uh are very far from my now how so
00:01:20
compared to benefit over that where all conditions i map your engineer
00:01:25
so for me it's a big difference talk about these things so since this is a a training even and the purpose is to learn
00:01:31
uh i am i i would like to invite you to interrupt me do you want to add something
00:01:37
or to be more precise about the things i i'm going to say because uh since i i already mentioned i buy
00:01:43
an engineer and humans when we have to solve problems we're
00:01:48
usually quite good solving problems but we have this um
00:01:52
this way we needed we we we basically make things simpler now we we try we try to model in in
00:01:57
the simplest possible way i'm part of a process i'm i'm very likely within when to talk about today
00:02:02
it's somehow ah oversimplified version of off
00:02:08
of the topic itself okay supported for that and so when you hear what what it was
00:02:17
myself invited to to talk about children that's a good question and but the main reason so the uh the
00:02:23
the topic of the of all the research president involved in english ones all children speech okay and and i
00:02:29
was a book i mean what the the thing that made me me alive to this topic first
00:02:35
and um basically we say say we we are recessed centre and we are
00:02:39
a classic about speech research centre in the sense that we we have been living for ages
00:02:44
a core speech an underling whisper a person technologies and we have been as as long as the
00:02:49
they have become a more mature we have uh something to to to apply to different um
00:02:55
application areas or i'm basically uh we start to like adults
00:02:58
everyone doing multimedia prescription and we have been since
00:03:02
two thousand eight doing the the captioning of the main problem television for broadcast news
00:03:07
and we we we did a lot of things like struggling with sees them switch to an ivy or applications of this kind of thing is
00:03:14
and as i mentioned as long as it's been more mature and we had when even more how
00:03:19
to do things with something to to to spur alder well implication areas somewhat emerging areas like
00:03:25
uh uh security and um and and and especially have okay and and
00:03:33
the reason is not only that uh um technology this uh it become more mature a listener case
00:03:41
uh that there are other reasons why that we use to this product have
00:03:45
applications of course because they are very interesting but they they also um
00:03:50
uh because in what usually they'll have a lot of data and these that may look
00:03:54
something bad is good because uh for instance i i sat course bits and other
00:03:59
language processing group we couldn't compete anymore with little princess green automatic speech recognition so
00:04:05
we get it we had to find ways of applying the things we now
00:04:09
a nah different and for the uh probably productive way i'm i'm listen to the things like a little therapist
00:04:16
uh based on the speech recognition and wanted to more not monitor is uh one
00:04:21
one of the guys uh you know the the the if this is isn't
00:04:24
and so on so basically this is a a more of the same or more specific of the kind of uh because of
00:04:29
we have been developing a really but i was able to speed and i'm positive communication disorders yeah and my role
00:04:36
i'm basically we had in like two thousand nine this project that was called the data
00:04:41
which was our retail therapy is this this one of here uh focus especially on a train innovation
00:04:47
and we didn't we label this uh where uh from then
00:04:52
we had is a little cut uh um basically
00:04:56
uh uh what what what where provide in its uh up up up front to provide a um
00:05:01
word them name initial success isn't looking of of of of disorder we were trying to to to pack a the
00:05:06
but this was uh were uh uh went into calling okay and that that's been successful we were very happy
00:05:13
and we sort of blow do variations of this for different purposes and
00:05:18
and like for instance um with this isn't really this elegant diseases
00:05:23
and some things like uh it could be interesting ration we're trying to things like um also the
00:05:29
discourse analysis of people are uh may have some problems uh describing a pictures and so on
00:05:36
and uh all these women can be quite fascinating and very interesting um
00:05:43
but um but we learn also something that somehow promoted
00:05:48
the uh the the interest on on on children's speech processing and i uh there
00:05:54
are many factors that uh that would you do this to to this interest
00:05:59
and uh and uh most of them i rented um we were the really basically
00:06:05
this its prototype the the we're not industrial the applications but uh when we when we got
00:06:10
the with with uh with with the patients on and on with people using it
00:06:14
we notice that we had a lot of talent especially when we're focusing on on
00:06:18
the sort of civil to do all the all the population for instance uh
00:06:22
so that was for us super today like using the most or something like that was really the people can be very difficult for
00:06:29
for the lower population so we we usually faced a problem would be the leader
00:06:33
see if you wanted to use this kind of would also be a environment
00:06:38
and and and sometimes people maybe we're a little or maybe just the use
00:06:44
of so the technology that we had some things in this implications within
00:06:49
the last uh people using where other people you usually and i thought
00:06:53
i might have seen problems and in big they became almost useless
00:06:57
so this we we found people were not probably too motivated neither because uh we we where it
00:07:03
works tire or whatever and on all these factors here in fact in insurance almost the oversight
00:07:09
children are a a cinema debatable is the part of the remote with the government to to solve
00:07:15
it they are um you have you you know how well they must be i'd button
00:07:19
and the cell phones uh it's incredible so they they they are very eager to to to
00:07:24
learn and they they they can uh not to need the the noses very silly
00:07:29
an and moreover uh one funk over the listen port what is uh i i don't know
00:07:33
the the the numbers uh specifically but that in in in what will the the
00:07:39
i don't know if the majority but many many of the the speech along with the with the ad
00:07:44
uh our with children so uh it has ah in that sense it doesn't canonical a reason
00:07:51
and of course i it was a lot of research silence that are interesting also for us
00:07:55
uh because uh from the uh when we've uh of a speech scientist
00:07:59
process in a a modern speech from type uh from two wins
00:08:03
it's quite more beef you grow and quite more challenging that uh the infirm models
00:08:07
and of course i it allows us for um kind of exploring um
00:08:13
some arm and bands and you want to call that way and you want to uh can guess interfaces like uh try to do interviews
00:08:20
and some elements of the amish occasion like you can see this in this picture
00:08:23
like using the boards and things um that it gets can very easily
00:08:29
i said and and and and use i'm i'm a divide them or what a broad inference in the speech of uh is he is
00:08:35
of a present with interaction between well once i'm i'm chilling with um
00:08:42
with the discernment uh with all this and uh this order
00:08:46
um so that's why i came up doing or be interested which respects okay
00:08:53
um and that's what a more disqualifies me from being here you can call this way
00:08:59
uh so uh this is basically online uh i i will do in a
00:09:02
very superficial way uh i believe of what it's the the the the speech of
00:09:07
decision process and how how speech and language is the there will be cute
00:09:12
an an and then a a will try to
00:09:17
two main it would uh it wouldn't there to see this guy but to name
00:09:21
uh what are the typical things that can go wrong and and and and
00:09:27
need some ideas on what when these things usually happen
00:09:33
and finally i. e. i will share with you
00:09:37
so maybe somehow we compresses to the speech or what what than typical ways on and i have some
00:09:43
experiments we we can not that later in as far as we can uh something or um
00:09:50
so um basically friends only only so with speech recognition development um
00:09:58
when when when people are insecure linguistics study the way that
00:10:03
children of where a speech elements scales basically the the gun different to be doing this
00:10:11
two groups of families or schools on the one hand we we talk about how we acquire
00:10:16
it's it's i'm basically a um i i refer with the speech to to to apple
00:10:22
uh articulation on intonation which can the six of us is so
00:10:27
how how we actually produce the sounds and and words ah
00:10:33
and secondly i would like to listen to the second element that that's important part on when we study hall
00:10:39
uh we learn to speak is how we had acquired a a language competence and basically how how
00:10:44
we use words to share ideas so we can buy these words how we learn different words
00:10:49
and and how we can use them to to make a ah a
00:10:55
a speech that it's that makes sense
00:10:58
i'm saying that that the main thing here is that the most children the blob uh uh uh this
00:11:04
is speech and the elements uh skills within the specific it it's a range see that there are
00:11:09
some some skills that appear on the certain it also always with a certain tolerance or with uh s.
00:11:14
s. and then have acceptance of different um but that they they are more more less common
00:11:20
always the the buttons of a speech elements of decisions scales and
00:11:26
and as i mentioned the that that that that there may be differences between the different uh it children
00:11:32
uh we submitted but in many different things like uh than the durability of sober
00:11:39
all the good to learn or many other skills that are like not at the
00:11:42
same time in some done is like a pimple too but still uh uh
00:11:47
how affects being willing well to the limits unsophisticated um process
00:11:51
uh oh and of course if they could it's various post to to to
00:11:56
to to speak for models they will learn a different way or not
00:12:00
and basically and the process of applying speech of course it's
00:12:06
um it's a physical uh after after deliberation process so
00:12:13
of course what we had the the the the we wouldn't return from from robert beginning
00:12:18
we're basically show the that that great or so and all the elements involved in in in the speech production
00:12:24
for the lee with we argued so we we have all of these already but it's
00:12:28
it's not mature enough so basically uh that i took this picture from from
00:12:33
one article and basically you can you can see that uh when we
00:12:38
are more uh not we we don't have just a simple but
00:12:44
that the uh that this version of the vocal tract but we
00:12:46
we have a quite different configuration i probably something similar happens
00:12:51
uh uh with a with a brain we we need also some uh it would we show for ordering so basically
00:12:57
uh learning language it's it's has these two two components in in one
00:13:01
hundred like a a physical evolution that needs to go together
00:13:06
so goes together also with with the decision of the skills that we need a it to speak and and to understand oh
00:13:14
and this is skills uh some of them uh you can imagine of of of
00:13:18
all the submission of the the publishers that was even in the first dog
00:13:22
that uh in order to speed we need to have very fine tuned ability
00:13:27
some motor skill abilities and i and this needs to be learned on
00:13:32
um but of course uh uh we also need to to to to double the uh
00:13:37
uh or ability to to to to to learn a new words and i'm
00:13:42
i'm basically as long as a uh sir brain get more mature and
00:13:46
that that is not the the difference in informations are are i don't
00:13:51
basically we we is something quite language skills on and and just
00:13:59
probably with the with the say here is that um if we want to compare the the the way
00:14:04
or the the the gonna be six of chilling the speech with all the speed um uh
00:14:10
at some point uh people just reduce everything to having a sort of vocal tract length
00:14:15
and which as you you know from the first term presentation probably that will cause the
00:14:24
actor for months now i'm having a shorter or smaller book of all that will
00:14:30
we sort of course in in or a fundamental frequency uh but is not only the is
00:14:35
in the process of learning that was since the day we we're born until uh huh
00:14:42
about eight years all the preserve of language acquisition uh um that many things
00:14:47
that are happening now and at different stages we have different abilities
00:14:51
and if we want to process this this this speech is it is maybe with the talent
00:14:57
i'm not sure what to say anything more about this
00:15:04
yeah for instance in this process uh not only we we we acquire a different phonetic sets but
00:15:09
uh and this usually happens more list early but there are other things that usually take longer
00:15:16
the point of a speech colour so like a like a intonational on or or
00:15:20
all suffer some lip service and then tell uh characteristics of the speed
00:15:25
um
00:15:29
so when i usually what the people of this to the speech a decision uh
00:15:37
do is to to to differentiate between different stages of speech act decision uh
00:15:43
and the speech development the in and the three stooges are those of here vocalisation but
00:15:48
because it's the very first one have into the at the very beginning of
00:15:52
when we are getting c. on six uh six months i'm basically consists on
00:15:59
on friday in green and and and this kind of things that inference when they are very small and and uh which it's
00:16:05
a interesting here is that they are very similar uh independently on the lot not so it's quite limiting pen and
00:16:13
and and and it's something that it's a it's a automatic i mean the the
00:16:17
uh kids can do even a in cases like mean uh where
00:16:21
they can hear another whether it is where the one left
00:16:25
and this happens but uh usually until six months of it's on our it's this is the the normal
00:16:30
uh one of the faces or one of the status of normal speech acquisition
00:16:33
the second one is what is called bubbling that the status after
00:16:37
local station where basically get a so to say things like that i don't have my my my my ah
00:16:42
uh but man and i i'm very simple the string some
00:16:47
songs that this this person's body is not actually um
00:16:51
yeah not ugly they say in words from fathers we like to believe that they say that bad
00:16:57
either pop up buying the space they them other than the thing saying what they are kind
00:17:02
of a wooden pipe is improvising the the the the vocal tract and so they are in
00:17:07
different something with a random way and and they are also kind of limiting the pen
00:17:12
um and more or less this the same the same sound so save in a in a it's in the
00:17:19
different languages but they're maybe emphasis of others around the language in intonation patterns in this kind of things
00:17:25
um what one of one particular thing is uh in that case you say that they've to
00:17:30
lincoln the model usually can a bottle and then the last estate uh uh that stars
00:17:38
on the the first year of age or when you're all it is the decision of idle
00:17:45
speed so the the question of the uh that well first real words no like
00:17:50
a a condition of of sounds of them may look like and what i what words
00:17:54
and this only have isn't uh in the first year uh only the first year
00:17:59
yeah i i and it's of course we this what i had this
00:18:04
the process of going from here to here and preserve all or when all the
00:18:09
time and the conditions uh it's not instantaneous is not the light that
00:18:13
when you're uh we uh some to master lessons moved initially but of course
00:18:18
and you know uh uh this sounds our choir in a in in
00:18:22
in in the something or other and this are there um it's quite common also against
00:18:27
a among all the all the languages uh typically a ball was a quite first
00:18:34
and concerns typically um there are some of them that
00:18:38
are easier and others that are more difficult and
00:18:43
and this is one usually are the that was the ones that are more
00:18:46
from about that and and and it may be related but uh
00:18:50
uh but the fact that the kids can they are not the greater the can see easier and and a a they
00:18:56
learnt upgrade easier or faster the the these these kind of sounds are the ones that are more front i'll
00:19:03
uh of course in the process of of of of assimilating the
00:19:08
different uh uh for means and and learn different uh acoustic
00:19:12
uh yeah sounds uh that there are many phenomena the last white with a lot of at
00:19:18
a loss for for four years or like and simplifications in a in saying wars
00:19:24
a delay shun sort of something funny institutions or assimilated shows like typically worse of the have
00:19:30
um the the basically the beating the the same phoneme in a war with two different phonemes but
00:19:36
that's similar and they they they repeat no in uh in order to simplify the mic
00:19:40
to make things easier and this may or less for what i consider the amount of time
00:19:47
so i have here a table yeah phone of a a for the development of
00:19:53
of the normal patterns of of of language acquisition and say
00:19:57
say that in the first ones basically it's just a
00:20:01
cool make noise as i will allow and to make playful noises and understand the
00:20:08
bubble at six months and say like to me and this can things
00:20:14
in when they are they they start to model longer and they made a little these uh um
00:20:20
what what it's called gerald or i guess the the maybe the beloved ability to read a
00:20:27
what probably you have the uh smoking you know and when you're the uh so that
00:20:31
you find the the keep uh like if they were talking and alien language
00:20:35
so they they they they they talk a lot but uh they it don't know long words
00:20:40
i miss related to kind of own jargon but it's it's into the a they are having a
00:20:44
conversation on this kind of things happen around one year and disappear at around two years
00:20:49
in one yeah they are able to to to to use most of the what what follows as
00:20:53
i mentioned the gentleman its goal and uh uh two years and the or something please uh
00:20:58
the use of words and how complicated the they uh it's gonna be by a class those the the news like
00:21:04
using concern them all of consonants uh of course the the the
00:21:07
arts institutions on admissions or or the phone to use
00:21:11
and the edge of three years uh to be a kid can master
00:21:17
most of the sounds i mean side words or the use properly the words and that is
00:21:21
not only the can say but it again mastered inside was like two l. p. m.
00:21:27
so that they are very frontal on or like we'll uh zones
00:21:31
and and this kind of phonological processes like changing a consist in
00:21:38
phonemes one but uh for the older and and this gonna things start to disappear but of course the the yeah still there
00:21:44
uh i had for years all the stump must and
00:21:47
more difficult sounds like the the k. e. e.
00:21:51
instead worse and and and and this this doesn't become
00:21:54
poisoned intelligible um even for a a and stranger
00:21:59
and more or less on the on the some pretty well for me it's all the band the looking but usually you can listen very well
00:22:04
and then this this poses goes on with five six years something must have more difficult sounds like d. r.
00:22:13
and finally at the edge of a seven years they end up a mastering uh
00:22:19
or i will this be a all the phonemes of the language this this time the suffering is it for the dimension
00:22:27
uh so this means basically that in terms of us a speech probably trying to get a a good system relies
00:22:33
in terms of what we can produce a and the age of eight which that's a means
00:22:38
the the speech production of acute anna offered to the of a domain
00:22:41
is equal to the the novel because as i mentioned previously
00:22:45
uh it's to a level got like it's it's
00:22:48
it's considerably smaller which basically means ah ah
00:22:52
already used them ah sorry i'm i have beat uh and and i had or um
00:23:00
i have a foreman so basically until poverty i would say the the
00:23:06
the the the this the speech coding says i still different
00:23:11
but the the the phonology progeny uh are already gotten from it gives all
00:23:17
in terms of of language development is this was only space production uh in order to produce a conference for speech
00:23:23
to learn fall or i usually get it that ice also different different stages
00:23:29
and the very beginning uh an instance when you're all once they can sing the first words uh that uh it
00:23:37
this is usually classify the verses in the name in a state where basically they can produce a the concert uh
00:23:44
that makes a little speech to a really willing to do all that an event
00:23:49
i'm basically use justin announce only nouns and and usually they did working generalisation that um
00:23:56
it or not not it's every possible a little man and this kind of things
00:24:01
ah then the second stages call all fast in the states
00:24:06
and basically this all festive thing means that um
00:24:10
i see the word is use the expand or or or two different to complete
00:24:15
company meaning of a of a sentence so basically nobody will the
00:24:18
key uh uh when the um listen to your soul
00:24:22
um you know that when they say once this we work mean
00:24:27
a whole sentence of intention the balloon it nobody will see
00:24:32
then there is this third states that it's called belly laughing it's it's just days where basically just
00:24:37
as in with your soul and did so they want to to form longer sentences of
00:24:42
you know two three wars uh but most of the of the elements of all the synthesis are announced
00:24:48
or probably also some jed the excel and but but there are no no for non functional works yet
00:24:54
and finally the last is that it's it's called more funny acquisition where
00:24:59
what keeps still to to to to acquire a more complex uh
00:25:04
part of speech yeah uh with words like open
00:25:09
positions and function wars uh inflections or something
00:25:13
flat and and this of things and of course this will also be the what was
00:25:17
this uh if this is there's this this goes on until yeah yeah they could of course
00:25:21
all the set of limits when it is that that we have a set novel
00:25:26
again i i i tried to do this kind of come part table um
00:25:35
to show how how things progress with the eight an essay mentioned at the beginning the first
00:25:40
zero is when it acquired the first war and then in one hundred years um
00:25:50
the look it's can speak about fifteen worth what well again and and so much more
00:25:54
begun and so the amount of two hundred and this this difference between him
00:25:58
production and and understanding happens also on the phone or a phonological level usually gets
00:26:06
i can't even see a the phonemes or obviously productions uh at the beginning of the lies
00:26:12
and it's stays on the the some phenomena like the fees phenomena or something like that
00:26:17
uh they they can distinguish feast on fridge from fish but they
00:26:22
cannot say so uh this kind of things uh it might
00:26:26
happen i break did not usually that the ability to understand it's higher and ability to to to to speaker previews words
00:26:33
with two two and a half years that they can seen much more words and they can understand a lot of things i have
00:26:40
one can just now with your somehow found in the sense everything basically
00:26:44
basic things of course um and the consultant produces model
00:26:48
uh is more sentences to four years uh
00:26:52
i'm just a little sent sentences more complex structures uh some to use different terms of a
00:26:58
space as i mentioned previously with inflated for some of them not completely right yet
00:27:03
uh but they can still uh some to produce the stories and and you can have begun how how was that
00:27:09
the school and they will answer and i'm basically how are when they had four lines and and these things
00:27:15
with five six years the the the the speech the language because fluent
00:27:19
and clear but the the maybe since undersea well articulation deficits
00:27:23
and and could have ah what we'll cover am concerned all it
00:27:27
which allows them to the superset deal of it on the site specific and
00:27:31
then you can see in brian you can just limits to negotiate to
00:27:36
to have a conversation of course i'm finally as i mentioned previously an age of eight you can have a another like conversation chill
00:27:50
mm going slower than expected
00:27:53
um
00:27:56
second topic okay
00:27:59
um and they didn't and i will sleep very fast because uh because uh
00:28:04
i i think that there's not much more people can probably more information more useful information
00:28:09
that they can but they at least one dimension and probably if a snapshot of
00:28:14
what are the main disorders or what the things that can go
00:28:17
wrong uh with children uh acquiring it's been so long but
00:28:22
so uh the uh well it's pretty obvious thing this is and this is a simple important for for other some for children
00:28:30
a limit it's it's it's and it's it's it's amazing could scale that 'cause i
00:28:35
had a lot of implications but especially when you are a child if you
00:28:39
if you you can all this be properly or you can understand properly you're missing a lot of things so
00:28:44
and and i'm basically this may have a huge impact in the way that the child all
00:28:49
the bills uh for the social problem you emotionally and for the good point of view
00:28:54
and and and and and it's a very important to be uh that this is one of the of of
00:29:00
helping or uh kids that might have at some kind of a speech on which these are the
00:29:07
i'm basically we we we say that uh uh tell that things longer than the basic cable the show show
00:29:14
previously that things longer the the the the table to learn some of the skills that are there
00:29:19
uh in that they might have a problem with problems i isn't is is not a automatic name is one of the things and
00:29:25
you have a problem and we get it is different of course i in this way by the way a professional but
00:29:31
let it maybe in indicate or i'm basically we can distinguish two two whoops
00:29:36
of problems according to the groups of skills that we have to develop also the what the first one it's a a speech problems
00:29:42
and these are listed typically the classify eight according of uh the for the for the effect with
00:29:48
articulation of stones over the the inability to put these properly the the the the the phonemes
00:29:54
or before losing the processes in which means basically they are able to do this properly the the phones
00:30:01
but probably the switch or the the lead in a in a in in a more or less regular pattern something
00:30:07
the two uh substitutions we have also the fluency disorders
00:30:11
basically the race in any influence to or information on a like start dating
00:30:17
for it and this these are to be confronting this are those
00:30:22
and and of course voice disorders bit which basically means uh the yeah
00:30:26
the inappropriate use of the vocal folds and uh or or
00:30:29
voice probably using a ah tomorrow to speech or to lie for
00:30:34
parole or not totally probably the the the the the boards
00:30:39
then the valley land what uh uh but i was just basically dividing the city
00:30:44
disorders which basically are really do too difficult eastenders then or process language
00:30:49
then expresses disorders which is the the basically the oversight if you lose the
00:30:54
using words expressing once uh of uh using limiting our number bin
00:30:58
way depending on the on the on the the the
00:31:02
the situation and also cognitive concussion disorders like a um
00:31:07
other than to skills or with the skills that will affect the the
00:31:10
winter this levels like memory attention and and this kind of things
00:31:16
these are some of the most common disorders i i think i will skip because i have
00:31:21
one one is like for each one of them are they uh we skin them
00:31:25
and just name they're just but it is not is very helpful to name them but the list you might remember them you ever see them again
00:31:33
and basically i in the speech disorders uh that uh that this is it's on the sort of the second from cumberland name
00:31:40
to collect the different disorders that might affect to articulation and and
00:31:44
and and to uh phonological processes uh for instance mm
00:31:52
oh yeah things like yeah like at least partly uh watching but isn't
00:31:56
could be a one type of these disorders or this the skins that says
00:32:00
digits or have problems with assessing lines which are which is very typical
00:32:04
and and the and these are all of these are those that in fact they affect articulation also
00:32:09
well uh one of them said uprights the office bits that uh it was serving mention eh
00:32:14
contain much more uh what was already mentioned that but basically it um
00:32:19
from from an engineer perspective uh it's half regarding the channel of of communication nowadays it's
00:32:25
uh the planning or or the the the orders of the brain are okay
00:32:30
they're the there's no winners in the in the the most in the muscles of of of of the speech production but the message
00:32:35
that arrives it to the uh to the to the the greatest is wrong i'm basically produces a it says this didn't understand
00:32:43
i cannot say nothing of smoothing of something more uh was always a main sound
00:32:47
three uh nothing more than that you can think of something to children
00:32:51
then we have or four or five tell me personally sort of uh basically uh
00:32:56
it does maybe he needs the uh uh the uh there don't goes
00:33:00
more in from the just it should go one basically it may you may find the when they eat
00:33:06
or drink but of course it into things the way they the producers bits and i stuttering
00:33:12
okay uh it can be broking like stall and encoding repetition of the beginning
00:33:18
that even without stuttering unvoiced problems that can be because we're different
00:33:23
types of problems with double curve falls like a um how i mean powerless vocal folds or or or or
00:33:30
or or all the cans uproar this uh polyps and and this kind of things in the mobile phones
00:33:37
the language disorders like pressed limits disorders that uh basically
00:33:41
problems that uh it might appear to invest yours
00:33:45
uh in a acquainted the basic yeah abilities of of of language
00:33:51
or learning disabilities a learning especially reading the spelling and
00:33:55
writing which um is nothing to do with the
00:33:59
intelligibility of of the key this basically how long is this or that and think it's a problems
00:34:04
may have problems we uh acquiring or or so it is it is like the most um
00:34:09
with this and may have been the key in this as an incentive situations doesn't speak
00:34:15
there are other medical but the conditions that of course can affect the speech and maybe important like a
00:34:20
tension there physically productivity bodies and of course the flip
00:34:25
appellate brain injuries that one's reported him problems
00:34:29
one of the main reasons for problems integrations because again cannibalism properly and not
00:34:34
your properly and of course the lincoln uh and to play properly
00:34:42
so we'll skip all of these
00:34:46
yeah
00:34:50
okay
00:34:52
basically what what are the signs of of what could have been one of these one of
00:34:56
these problems of course is more or less much and they were they mention before
00:35:01
and uh or a shoe before and and and the problems that they just escape ends and i seen the things are
00:35:06
not as it should be at the at the specific age now so basically a lot integration not saying properly
00:35:14
some of the sounds on the age of one two years might be an indicator of a problem
00:35:19
or not saying these ones cagey up t. v. i. the two three years uh it might be a problem
00:35:26
i mean very hard to this than even for the family members at the age of three four gonna get something also
00:35:34
starting studying something it's quite usually didn't get what she disappeared so at some point and if it's the innocence has
00:35:41
disappeared with two and a half years or three years that the maybe a ah an indicator of a problem
00:35:48
lynn was disorders of course having a horse a voice with simple is
00:35:52
something very nice l. that could be an indicator or um
00:35:57
and he losses emissions uh it can be very important it in integration problems
00:36:02
so things like not paying attention that sounds when they're very young not responding not following simple directions
00:36:09
or or show when speech on the delays in maybe because they don't uh here properly
00:36:16
in terms of land well it's not the bulb in this 'cause they are support of
00:36:19
listening of the smiling or playing a babbling one of the display previously uh yeah
00:36:24
make him a few noise uh is not understanding other saying only the few words in
00:36:29
two years all age shows shouldn't be that way and not been able to work together
00:36:36
saying less of fifty words and and trouble communicating with our kids and having fun
00:36:43
so usually that enables the the way it goes it par and or or or or professors
00:36:50
you can defy some of these signs and they go to a speech language pathologist
00:36:55
and of course the specialist poses will evaluate ah could someone of things
00:36:59
in order to see if the sample your problem and in order to to decide
00:37:03
or determine which is what is the ad paul problem there is there
00:37:08
and i it with one way or another scale says product shown to
00:37:11
smell the the the the the difference 'cause we can be mentioning
00:37:15
and and and at some point basically the the other one was with you before it very best to the
00:37:20
uh next point uh it's kind of what was discussed at the at the beginning of the session
00:37:26
and for me to one of the reasons for for for this profit or one of the limited is that um
00:37:34
the special about pathologies would use a it they know later experience the train and pray and
00:37:40
training to the previous observations to to to make a judgement about the key no
00:37:46
uh i don't and they use it for in order to diagnose one of the problems
00:37:51
but also to to decide which is the most convenient therapy and to
00:37:54
read the proposal of the therapy and and and this this this
00:37:59
this assessment is of course subjective with with the mission based on all on these factors uh it just mentioned
00:38:07
so
00:38:10
i have like five minutes or something like that
00:38:14
uh yeah
00:38:16
it would move to the last point and i will try to get on with these these reasoning basically
00:38:21
i don't know whether what is the opportunity or what uh what we can do
00:38:26
engineers like myself in order to help uh you know these are the speech processing methods to have with
00:38:35
um
00:38:38
with the speech pathology sentence with the speech pathology is and i think a copy this is like from one from elm are already it's another
00:38:44
one i so want from her like i want basically the idea is that uh um one of the things that technology can provide
00:38:51
that is an objective measure or negative evaluation of all these things
00:38:56
i mentioned previously that it's subjective for his bitterness bulges
00:38:59
which doesn't mean that it's better for sure to reward but it's analysis of each object if in the sense
00:39:05
uh for the same sample them so we will be always the same and
00:39:08
a and if we as engineers on myself as an engineer we're able
00:39:12
to to to to come to the bride with them to the version of corporate that was you got the speech and i put children
00:39:20
but it's not the specific fertility reasoning for for any other logical speech we can use this much
00:39:25
of do many things and to the will of many of the applications they show a beginning
00:39:29
so basically we can do for we can just for the nicest a formal and we'll uh evolution and to uh
00:39:36
a lot of you at a recent got interesting slow little
00:39:40
intelligible is the patient we can do for screening populations
00:39:43
uh we can use uh from only to to to to evaluate to
00:39:48
uh the two there's a speech according to what do you suppose for for for the air it's
00:39:53
that they it a page and and we can use also as a kind of shaken opinion
00:39:59
um i have an automatic objective measurements uh probably
00:40:04
depending on the on on on the specific topic where they maybe invariably the the me a lesson liable
00:40:11
and of course we can use for the robin or or for helping on saturday i for a sturdy control and to check
00:40:18
if the person has improved because we use always the same i
00:40:21
thought the phonology the same objective a measure of um
00:40:26
companies also be method and of course to to the blob like computers is
00:40:32
the light therapy like the one say action adventure so the beginning
00:40:36
um what are the kind of automatic speech process since that may be useful
00:40:42
in this in a in this context what basically i would say
00:40:48
to that that they are twenty one now we can the kind of
00:40:51
things we can do it in a given ah a certain signal
00:40:56
and some some training data we can try to select something for characteristics and do our model
00:41:03
or train model of of a specific and is a good one to detect or we want
00:41:07
to uh one way this model can be a classifier like to distinguish between uh
00:41:12
who doesn't wrong or a specific song or a different one on it can be uh
00:41:17
yeah i've wrestled like trying to pry that and number for the specific uh evaluation
00:41:23
and and of course to a we can explore different the the very definitely stick addressing traits depending and
00:41:29
very different malls depending on the kind of problem we well we want to to face and saul
00:41:34
uh at this usually what's well when we have a one to one problem in the
00:41:39
sense that we have a single others we have to put a single labour
00:41:43
uh when we have a single utterance which is tangled seems like
00:41:47
a speech and we have to provide seen uh it
00:41:52
several labels like us imitation uh the the the the problem it's how more complicated but
00:41:57
this is only what happens in automatic speech recognition that we have a single time
00:42:02
a signal but we have to provide a sequence of labels of classes is a word and there's still a problem
00:42:10
seem similar but instead of coming jessica's indication we cover so that we call the korean
00:42:14
so that and instead of having a single model we have twenty quid or no let's not in a more efficient way
00:42:21
and i'm basically if we want to use this kind of technology is with the speech but uh
00:42:27
apologies on with children uh that we will probably have to uh that deal with all this
00:42:35
not a source sources of knowledge we have plot that probably or at least in all those or language
00:42:40
most organisation most to the the characteristics of the of the speech we want to to treat
00:42:48
and of course the this is this the the s. r. is quite the model like for in any kind of analysis we want to
00:42:54
do it because it's it's it's it's basically for brian for the line for instance even if we we do a forced alignment
00:43:00
if the if they cut the six of the of the speech we're processing it's very very different from the training once uh probably
00:43:06
the lines not that would on and and the the the the the countries we can take from these ursula are useless
00:43:15
what is special to the speech and it is our well basically when you use a start and that
00:43:21
has been trained for a those with children due to the different characteristics that they mentioned before
00:43:26
and to the uh the people to to control the articulators before
00:43:30
they years and the the different phonological process that happened uh
00:43:35
it fails it doesn't work was very bad usually um
00:43:41
and as i mentioned is the target by idea 'cause ages also and also because
00:43:46
we don't have as many data from children train as we have four hours
00:43:49
and and i've here at this at this at the this coming few data
00:43:54
is a typical adaptation problem in in automatic speech recognition or the
00:43:57
minute they some problem and there are different ways we can try to to to fix these we can do uh the feature level
00:44:04
so the first block with a mention a happier and at this level the typical thing that people do when they want to
00:44:12
processing of office which is what they call vocal tract length normalisation visible but i let a let is shorter
00:44:19
than try to spend uh the mullet tonight in order to to meet me the one from another
00:44:24
mm which works more or less not really uh people also use got the features in
00:44:32
order to to to to to show up with a specific of the six of
00:44:36
children speaker features like this and i beg or something like that
00:44:40
or or tickle the features or or what is this here
00:44:43
in in for this uh it's a metaphor didn't speak it that it's become active training which basically means that you
00:44:49
do a model that uh somehow incorporate information from the speaker and it's better and it should be something
00:44:55
which would make sense to do with kids because they are very even among each other and with the the l. data then of the model level
00:45:02
that a bunch of thing means we can explore all than with the with attention
00:45:06
like transfer learning does learning using more other than on on children data
00:45:12
it's about them all in this is very important because basically uh their base even um
00:45:18
the the kids change a lot the way the this baby yeah age and have been it's been one can help a lot you shouldn't use
00:45:25
a single to this it's more for doing this are probably you should tell you see more than one uh depending on the age range
00:45:34
i i and i probably will stop you because uh uh we have a a present going on
00:45:38
i just to confirm what i what i'm telling you we we we were happy enough to to find some data
00:45:44
import to is which is difficult but it's not uh is the that is like read the speech and we have been doing and if we're to collect
00:45:51
uh yeah additional data from kids doing typically spits on the television task like
00:45:57
a naming walls uh some uh the the the the kinetic yeah
00:46:02
yeah that's like a pick up the kappa kappa just involve well some sounds and so on how we're doing
00:46:08
curly when fanatical annotation which is we will allow us to do a little things i just um
00:46:15
we need some really nice payments just you know our system that was so far with all the space it's not the state of the art
00:46:21
this is for the speech yeah we should have like a seven or eight percent were right
00:46:26
uh but this just to show you the weather was mentioned other things don't really wear when when i use the same system that gives
00:46:32
i'm fifty per somewhere right in with all those to children able to one hundred whatever which means
00:46:38
that nothing works to the nothing works and we have been doing some uh adaptation experiments
00:46:44
uh this is different different configurations of of of the acoustic networks and
00:46:49
we're able to record some of the everybody still we're very far
00:46:52
of all would prefer menace our system that allows us to do it meaningful objective measures
00:46:58
so
00:47:00
i'm i'm
00:47:02
and on this is huh
00:47:12
okay i'm sorry that's longer than spike that okay thank you
