How does iTalk2Learn enhance students’ learning experiences with feedback adaptation? We at Birkbeck and IOE are very interested in finding out how feedback can be adapted in line with students’ affective states. The task-independent support within the iTalk2Learn platform is able to tailor feedback types, as well as presenting feedback according to the affective state of the given student.…
Conventional speech recognition systems are failing As previous research has shown, there are many differences between the speech of an adult and that of a child – both acoustically and linguistically. That is why conventional speech recognition systems modelled on adult data are failing to perform satisfactorily on children’s speech input. Speaking isn’t straightforward Human…
What have we been working on? At Birkbeck College, we are currently implementing the task-independent support. In collaboration with the IOE, we have analysed the Wizard-of-Oz studies, using these results to inform the design of the task-independent support. What did the results show? Speech recognition from our project partner, Sail, is used to provide feedback based on…
In an earlier blog post, iTalk2Learn partner, Sail, talked about the statistical nature of the two models which are employed for automatic speech recognition: The acoustic model The language model These models need to be trained on a so-called ‘corpus’ before they can be used in the recognition process. In this blog post, we’ll hear more from Sail…
