Title: Applying Articulatory Features in ASR for non-native Speech
Speaker: Yunghui Li

Abstract: In this talk we will present the E-language learning system ELLS, a joint
project by the US Department of Education and the Chinese Ministry of Education. 
After briefly introducing the internet based learning environment
we will characterize the non-native speech we are facing in this project
and then describe our experiments with Articulatory Features. By combining
the AFs with traditional phoneme models, enhancing the context free grammar
of the recognizer, and performing supervised and unsupervised adaptation schemes, 
we improved the speech recognition performance on non-native low proficiency speech.
