Biography
Chin-Hui Lee is currently a professor at School of Electrical and Computer Engineering, Georgia Institute of Technology. Dr. Lee received the B.S. degree in Electrical Engineering from National Taiwan University, Taipei, in 1973, the M.S. degree in Engineering and Applied Science from Yale University, New Haven, in 1977, and the Ph.D. degree in Electrical Engineering with a minor in Statistics from University of Washington, Seattle, in 1981.
After graduation, Dr. Lee joined Verbex Corporation, Bedford, MA, and was involved in research on connected word recognition. In 1984, he became affiliated with Digital Sound Corporation, Santa Barbara, where he engaged in research and product development in speech coding, speech synthesis, speech recognition and signal processing for the development of the DSC-2000 Voice Server. Between 1986 and 2001, he was with Bell Laboratories, Murray Hill, New Jersey, where he became a Distinguished Member of Technical Staff and Director of the Dialogue Systems Research Department. His research interests include multimedia communication, multimedia signal and information processing, speech and speaker recognition, speech and language modeling, spoken dialogue processing, adaptive and discriminative learning, biometric authentication, information retrieval, and bioinformatics. His research scope is reflected in "Automatic Speech and Speaker Recognition: Advanced Topics", published by the Kluwer Academic Publishers in 1996. From August 2001 to August 2002 he was a visiting professor at School of Computing, The National Univ. of Singapore. In Sept. 2002, he joined the Faculty of School of Electrical and Computer Engineering at Georgia Institute of Technology.
Prof. Lee has participated actively in professional societies. He is a member of the IEEE Signal Processing Society, Communication Society, and the European Speech Communication Association. He is also a lifetime member of the Computational Linguistics Society in Taiwan. In 1991-1995, he was an associate editor for the IEEE Transactions on Signal Processing and Transactions on Speech and Audio Processing. During the same period, he served as a member of the ARPA Spoken Language Coordination Committee. In 1995-1998 he was a member of the Speech Processing Technical Committee of the IEEE Signal Processing Society (SPS), and later became the chairman of the Speech TC from 1997 to 1998. In 1996, he helped promote the SPS Multimedia Signal Processing (MMSP) Technical Committee in which he is a founding member.
Dr. Lee is a Fellow of the IEEE, and has published more than 250 papers and 25 patents on the subject of automatic speech and speaker recognition. He received the SPS Senior Award in 1994 and the SPS Best Paper Award in 1997 and 1999, respectively. In 1997, he was also awarded the prestigious Bell Labs President's Gold Award for his contributions to the Lucent Speech Processing Solutions product. In 2000, he was named one of the six Distinguished Lecturers by the IEEE Signal Processing Society.

Biography

He holds honorary doctorates from European and Far Eastern Universities, several Visiting Professorships, Distinguished Lectureships, Fellowships and other honors around the world. He served as a Member of the Board of Governors of the IEEE Signal Processing Society, a member of several Technical Committees of the IEEE and the Institution of Electrical Engineers (IEE), U.K., and is on the Editorial Boards of many professional journals. He is a Fellow of IEE and an honorary member of Eta Kappa Nu.

Biography
Wan-Chi Siu received the Associateship from the Hong Kong Polytechnic University, the MPhil degree from the Chinese University of Hong Kong and the PhD degree from the Imperial College of Science, Technology & Medicine, London, in 1975, 1977 and 1984, respectively. He joined the Hong Kong Polytechnic University as a lecturer in 1980 and has been Chair Professor of the Department of Electronic & Information Engineering since 1992. He has published over 250 research papers, over 120 of which appeared in international journals, such as IEEE Transactions and Signal Processing. His research interests include digital signal processing, fast computational algorithms, transforms, wavelets, image and video coding, and computational aspects of pattern recognition and neural networks. Professor Siu was Guest Editor and Associate Editor of the IEEE Transactions on Circuits and Systems, Pt.II between 1995-97. He is also an editor of the recent book, 'Multimedia Information Retrieval and Management', Springer Berlin Heidelberg 2003, and a member of the editorial board of the Journal of VLSI Signal Processing Systems for Signal, Image, Video Technology, the EURASIP Journal on Applied Signal Processing, Pattern Recognition and a few other journals. Prof. Siu received many awards, such as the Distinguished Presenter Award of the University Management Workshop of the PolyU (1997), IEEE Third Millennium Medal for Outstanding Achievements and Contributions (2000), IEEE USA, and recently the Best Teacher Award (2003), EIE, the Outstanding Award in Research & Scholarly Activities, Faculty of Engineering, PolyU (2003), Plaque for Exceptional Leadership and Significant Contributions, IEEE SP Society Conference Board (2003), IEEE USA, and Honorable Mention Winner of the 30th Annual Pattern Recognition Society Award (2004), USA.
