Hello everyone, I'm Yunhan from University College
Dublin, I want to talk about to the paper "See What I'm Saying?
Comparing Intelligent Personal Assistant Use for Native and
Non-native Language Speakers". And the we can know speech interface
are growing in popularity. People can use speech interface
to deal with some simple tasks like to ask for time, especially
this kind of technology is useful in something like hand
busy and eye busy conditions. In this paper, we
focus on the non-native English speakers also called L2
speakers, because the IPA design are more focusing on native
language speakers rather than non native English speakers.
Also, because of the language limitation. L2 speakers face
more challenges. when they use this kind of technology. So, in
our research, we want to focus on this group of users and to
identify important issues in L2 IPA user experience and they use
two different type of devices. That is Smart speakers and
smartphone to figure out the device's performance between
native English speakers and non native English speakers. And we
design an experiment for the study in experiment study 32
participant were recruied from the University 16 native
speakers and 16 Mandarin speakers. They were asked to
interact with Googlr Assistant including smartphones and smart
speakers condition to finish a set of tasks has shown by
pictogram. The test was including six simple
interactions. And after the after the interacing with both
devices participant took part in our semi structured interview to
focus on the experience of interaction and their devices
performance. And this is a pictogram we use and in study.
We found that interacting with IPAs, L1 speakers more for
structuring their commands as simple Possible although L2
speakers also tend to find that and adapting their natural
speech, they focus more on how this was driving by perceived
languages limitation, especially pronunciation, vocabulary,
knowledge and retrieval. And also poor IPA waking and turn
taking was a problem experienced by L2 speakers. In contrast, L1
speakers feel that the time between production and
recognition was too long which could disrupt the interaction.
And L2 sperakers found that the visual feedback provided through
the smartphones is a very important in supporting their
interaction. It can helping them diagnose reason for their
interaction breaking down also can give them confidence in
system's ability to understand their utterance. L1 speakers, on
the other hand, feel that to the audio only feedback is enough.
And L2 speakers also mentioned the different difficulties in
producing the correct words or the pronunciation of the words
to interact effectively with IPS. So in this research, we
found that to user tend to regard to speech interface as a
poor listener, which could make the users to change their
speaking strategy to simple commands. And L2 speakers seem
to feel more stressful for the for the interaction failure. And
L2 speakers prefer the devices with visual feedback since the
permanence of supplementary visual feedback may give the L2
speakers extra time to gather more informations that may to
improve the experiments. And also the vocabulary retrieving
issue across multi language cause the problem when L2
speakers uses speech interface, maybe the future research could
focus on how to relieve the burden of the production for the
L2 speaker interaction and in the futurework, maybe we can
expand the L2 participants group not only for the Mandarin
speakers and then we may focus more on the cognitive
implications of L2 speakers interaction. Thank you
