In BCBL the bask center on cognition brain language so, G, he, he was awarded the project, the, the travel grant last year with a project title does not native directive speech Enhanced non-native listeners critical tracking.
So Georgia, we're not talking just about that. Jordan will be talking about his PhD project and also a little bit about what he did here.
And one cool thing that he did and was to complement the scholarship that he won through the workshop with some other funding.
And so we managed to spend 3 full months in Dublin. And so he managed to collect data and also to, you know, his close to publication with that.
And so that's the kind of idea that we like to promote, but. Even if you wanted to come for a week, that's still okay.
Are you online?
Is George online?
Okay, yeah, yeah, I, I couldn't, I muted myself. Yes, sorry.
That's fine. Welcome to the workshop again, Giorgio. And the floor is yours.
Thank you. Thank you. Okay, I think, yeah, I'm trying to share the screen.
. Not Right, here we are. Alright, so well, thank you for all, Joandy, everybody from be here.
I guess you can hear me well. If not, please let me know now. And so yeah, I'm gonna talk about, well, mostly actually the project that I carry out during my Christian stay at Telanus Lab.
That well the title I gave slightly different so non-native direct speech supports and to learn this corporate tracking speech but it's basically the same thing.
So it's also part of the bigger project of my PST station. It's all about non-native director speech, which is a speech register.
And Sorry, okay, it works and it also has other names for some foreign director speech. Usually, a non-native director speech is the prefer name because it's more neutral term.
But for this presentation, I'm going to use the acronym from the old name of the state.
So FDS, just because it's easier because it will be compared to native director speech, which is, well, the acronym is NDS, of course.
So, just to make clear, it's not foreigner, Sanders speech would be the guy here in the white speaking in English for instance.
It's about the way native speakers like the English girl left, but it could be any language of course.
That's the way how she speaks. She addresses, Mel T, so someone's learning, English in that case, a second language.
Fds as compared to native language speech, it increases speech clarity. And this is reflected in some of the features.
For instance, North speed train, so for, it will be a low number of syllables per minutes or hours per minutes and also an expanding vocal space is known as vowel hyper articulation.
Just to give you like a graphical representation, there's nothing the meant to understand that this presentation.
But this is how we calculate our population. They'll be taking the first 2 4 months of the vowel production, plotting on a criticism plane.
And then we calculate the area, the triangles. The red triangle represents how at the GERL left will address the guy on the right.
So, a hyper articulating power. So producing a vowels far away from each other. And the blue triangle represent the way the vowels of native vector space.
So how you speak to another native listener. And this is interpreted as being promoter of language learning and also processing because it supports detection vocal consciousness because they're easier to detect, so they're also overlapping.
Apart from that, apart from assumptions, we also found in our latest study that's now under review.
There and L to learners when they're exposed to FDS, they actually learn better, faster and no worse as compared to participant were exposed to an And so it seems to be a tool for teaching a second language.
And we use single representation, a short presentation, sorry. So it is still unclear whether FDS, but most of the perception of continuous speech would be like more in that, yes, but most of the perception, continue speech, it would be like more in that realistic environment.
So, and also, beaver studies were mostly most studies on FDS or behavioral.
And that do not allow us to investigate the process of ultra processing while this is going on. But when it's already completed and of course you know that EG allows that.
And And so anyway, so far there's just a single study on foreign director speech with EG.
It was doing single presentation, single representation. There's nothing on continuous speech and ecological body stimulate.
And so one way of course to investigate whether FDS supports through processing is by using EG and measuring cortical tracking of continued speech.
Well, there's no need to say this, but we'll say anyway, so are you tracking a synchronization of cortical, cortical, sensor activity to fluctuation of sudden stimuli.
Of course I write it. And of course, one feature you can study is speech. The most typical feature.
So this is embedded evidence showing that already tracking speech, especially in low focus events, usually that's the more or less.
Is a marker of underlines process. And And that's also some evidence showing that it's fundamental for other speech processing.
In some cases, a quarter track has been linked to speech clarity, possibility, and so on so forth.
And also as has been studied in infant language development. So really in relation to infant right to speech there is another speech register in this case directed to infants and which shares a lot of features with foreign direct speech.
So it is possible to explore to investigate coordinate tracking using temp response function. Of course, you're here because you know what is.
That is, RIGALIZED linear regression. That maps it to the continuous stimulus to an error response.
And I think Joanne is familiar with this figure here. You know that. And, and then it's possible to using the giraffe to predict UG response and correlates it to actual EG activity.
So this is a one possible outcome, one possible and variable. And using this presentation. Okay.
Another interesting feature of TRF that's possible to see by your sets of features, not just like a speech handle for other features that are known acoustic too as well.
For instance, like Samantha, say. And of course you already know why would actually going. So we aim to measure what you're talking in foreign director speech and then yes, so native after speech.
But in literature, it has been shown that Korgo tracking is also affected by speech rate. And so we for this reason we had the third condition that we call slow NDS.
Which had the same features of ideas. So actually we we use and yes, and then we slow it down to measure the speech rate or FDS and we did it by means of Well, sorry, I will say this is the next slide.
Then I'm, sorry. So and slow in yes, and so slow and yes doesn't have any feature that is supposed that is expected to support and to learn as perception.
And also, well, it has never been addressed, but of FDS and Portuguese, you know, second language speech.
And of course, it's important and supportive to shut light at this point because it will tell us more about how a second language is process also acquired.
Because of the features of foreign director speech that I told you about before, and they're adapted to the Learner and FDS is a certainty remote as I said I do processing but not at yes.
And this should be reflected on more efficient target tracking life. Yes, then and yes. And this should be true just for alcohol.
So in the study in the British study, we aim to answer the question here. So the first question does FTS promote L to learners cardic tracking speech?
And if you have time, I'll just give you a hint about the next. You're running.
Just the second question. So, and we're into experience. So they were collecting 2 different experiments.
Why to experiments because we were 2 different labs like Spain and one in Ireland and also with 2 different systems.
One is by a seminal one, it's a great vision. So in the first experiment, we collected a from 25 at to Burns of English.
Who was just, who's as one L one as Spanish. And then the experiment, so far, 1880, native English listeners, we are still in the process of collective data.
And all the participants listen to continuous speech inform us covertelling in the 3 store in the 3 conditions.
And each story was about 50 min each and well the stories were called where I recorded in the British English accent just to make it make it easier for English for Spanish participants.
So while we were listening to the story of scores, we record their participants, the EG activity, and we also ask them to ask some questions about the content in the story in total with the after each break as a 5 question for about 25 questions the story and also we where we went for TF model.
So the low focus events want to get herts and for the features of speech and look so far. And here we are the results.
And for the comprehension results. And for the potential score as expected, we found main effects be register and participant respond with higher accuracy.
It was stories when the story was pronounced and foreign direct to speech as compared to the other 2 conditions.
Here I like to involve the main comparison of interest, which is foreign vector speech versus NDS, Native American speech.
And this is in line what we were expecting. And so they seem to be more accurate, so to understand better, say, and the stories in F.
Yes, of course we know there are other funds, so we cannot conclude much. So because there's tension, engagement, but this is still the first results interesting.
So for this reason we also had more of course check you measure and we use prediction correlations of the mode node for TF model.
And we found that participants showed higher petition correlation when they listen to stories in foreign right to speech as compared to native direct speech as compared to slow and yes and again here the interesting comparison between FDS and then yes and so it seems that they were encoding better speech handle aware with this name to FDS.
Okay, so then the results of the English Lisa group. And I suspect that we didn't find any difference across the precondition for the compression score because the the native so they don't need any any acoustically featured development, understand process.
And the stories. And we also, well, like was to stress out that there's no sending effect.
We made sure that it didn't go all the same wrong answers. There's some variability which is important as well.
And for the traditional relations, we had something that was kind of unexpected and because we got a higher pollution correlation and yes as compared to FDS and slowness.
So we're expecting that because of the slow speed trade or because of the who to feature somehow we will observe hibernation correlations in FDS and slow india.
But instead it seems that it's more important the fact that NDS was sweated so it was like a man to address native listeners.
As it was the same for F, yes. So just to then now I will just sum up all the results.
That'd be clear. So. And we asked ourselves whether FDS supports processing of continuous peace, especially for learners.
We found that it was the case, at least for the, results. With the limitation I said before and we saw we found the same well Congrent like assistant results for the TRF.
And in fact, we found that the Spanish Lisa had high British relation FDS whereas English Lisa had higher prediction, prediction correlation in MDS.
So it seems to be the case that is not just FBS having some sort of some special acoustic features that make the, you know, make space to be encoded better is the fact that they are the men they intended atrocities of those speech registers and also it seems to suggest the results seem to suggest that this is not an effect of speech rate.
Because of the way we find the same fact in both groups. So there was low speech rate, would drive the fact and this was not the case.
And also we will find the same fact for flow ideas since it was as lower as low as FDS.
And one might ask whether slow india was like weird or natural and we don't think so also because we would expect an effect here so we don't find that we didn't find any difference between FDS as low NDS in the in this different group.
So probably must probably was just a matter of fact that they are not exposed both groups both experiments, the participant nox usually exposed to slowing yes because they are they are either exposed to FDS, is there are no native and to end yes and yes if they are usually you know interact with other native speakers.
And so these are results for the presentation today and just a quick lean on the ongoing analysis. So we are trying to answer that question more than about companion should be how FBS supports El Dulinus, symbolic and pointing, let's say.
And so you use GPT to destruct some of the surprises values and of course we align them to the opposite of the worse and so we're using again to ref model so for a model to predict a response.
But so I have no time to show. SIR, but I have some time for some questions if you have any.
Thank you very much. Hope wasn't too fast.
Thank you.
Great talk, Giorgio. Again, feel free to raise your hand. We'll,
On mute you were allow you to unmute if. Yeah, I have a question or you can put a question in the chat.
Have one for Georgia.
I did have a question. Actually, Ed has a question. This would probably be way better than mine.
Hi, Georgia. Thanks for the nice talk. And hope you can hear me okay. I'm in a different room now.
Thank you.
I'm I just had a quick question about how these results might fit with them. I know Giovanni has published paper before looking at using a lot of the EEG measures to determine someone's.
Abilities in English for example as they go from a novice to an expert or a native speaker.
Is there is there a relationship there with what you're finding in terms of this foreign? I know it's a different question, but I'm just wondering if if there's still a
Yeah, I mean, we are thinking about using the coding and to, to call the comprehensive score they got.
So in that case, I think will be something more similar than from here. And yeah, so in I think you're referring to the ones paper, point 21, 2 speakers.
And in that case, of course, there's no variation between speech registers. So it's just English as it is and most probably I think they use like native direct speech because like stories.
So, that's allowing common, of course, and by that case, would be, well, we didn't have any variability between, well, we have some variability, but not that much between the for the Spanish listener group.
So they are all mid low proficient. I guess, well, I was back to find senior results.
But it would be interesting to see the recording if we sign find something different for like NDS and and FDS and that piece.
So I have that we I will work on next future. Thank you.
Any other questions?
There is a raise hand.
Accidentally muted you Marley. So you can unmute again.
Hi. Yes, I'm, mated now, I guess. Can you hear me?
Yep.
Yeah.
Thanks.
Thanks for a talk. It was, really cool, cool project. And maybe I'm missed it, but How is the acoustics of the speakers?
Are they those 2? Are they from the same speaker? Or not?
Yeah, yeah, sorry. I didn't say just for my time mostly. But yeah, it was the same speaker that recorded the same story twice.
So the same British speaker, female. And then we transform from NDS. We just going to slow NDS.
But yeah, we compile between FDS and DS and ways the same speaker is.
Okay, cool. Thanks.
Okay, so if there's no other questions. Leave it there. Thanks again, Giorgio.
Thank you. Thank you, everybody.
It's a great job. You did a lot of work in, Short amount of time actually not not quite so short, but you did a good job and your project so Thanks for setting a good example for whoever follows next year.
So we'll. Ended it there for this session. That's the last.
