MADELEINE BATES is the Assistant Department Manager for Speech and Natural Language Processing at BBN Systems and Technologies. She is responsible for the technical and administrative direction of research and development efforts, including spoken language understanding, human-machine interfaces incorporating natural language processing, and the development of evaluation methodologies for those areas. She has more than 20 years of experience in research, development, and application in many aspects of artificial intelligence and computational linguistics, including syntactic processing of English by computer, speech understanding, knowledge acquisition for NL systems, computer assisted language instruction, interfaces to data bases, and human factors studies. She is a past president of the Association for Computational Linguistics.
ROLF CARLSON joined the Department of Speech Communication and Music Acoustics, Royal Institute of Technology, Stockholm, Sweden in 1969. He has been active in the department since that time, with the exception of two years of employment at MIT in 1978-1979 and 1990-1991. He also has academic merits in general linguistics and phonetics. His first studies concerned perception of speech, e.g., models of vowel perception. In 1977 he received his Doctor of Science degree on the subject ''Perception and Synthesis of Speech." His main activity has been to create possibilities for converting text to speech. This research formed a base of the company Infovox, which was created in 1983. Since 1970, he has published extensively on speech synthesis, speech perception, and general phonetics. His recent activity includes the development of a dialog system based on speech technology. He is currently Advisory Editor of the Journal of Phonetics.
