Recent Work at National Taiwan University on Spoken Content Retrieval and Computer-Assisted Language Learning

Talk Title: Recent Work at National Taiwan University on Spoken Content Retrieval and Computer-Assisted Language Learning

Abstract: In this talk some recent work on speech processing research at National Taiwan University (NTU) will be summarized. The first part of the talk will be on retrieval of spoken content semantically related to the query but not necessarily including the query terms. This problem has been widely studied in text information retrieval. In this talk we will show how text-based techniques can be translated into approaches for spoken content. The second part of the talk will be on a dialogue game framework for computer-assisted language learning. This work extends our previous work of NTU Chinese, a Chinese pronunciation evaluation software tool, to develop a dialogue game. We use reinforcement learning to train the dialogue manager with a goal to offer learning materials adapted to the learning progress of each individual learner.

Biography: Lin-shan Lee has been a professor of National Taiwan University since 1982. He developed several early versions of Chinese spoken language systems (text-to-speech synthesis, large vocabulary continuous speech recognition, etc.) in the world, and was elected as an IEEE Fellow in 1992. His recent work is more focused on speech recognition fundamentals (features, models, robustness, etc.) and network environment problems (e.g. retrieval, semantic analysis and educational issues of spoken content). He served as the Distinguished Lecturer of IEEE Signal Processing Society (SPS) (2007-08), a member of the Overview Paper Editorial Board of IEEE SPS (since 2009), and the general chair of ICASSP 2009 at Taipei. He also served as a Board member of the International Speech Communication Association (ISCA) (2001-09), in which he initiated and coordinated (2006-09) the ISCA Distinguished Lecturers Program. He was elected as an ISCA Fellow in 2010.
