The information contained in speech can be classified into three categories: Linguistic, Paralinguistic, and Nonlinguistic. Paralinguistic information (such as information concerning intention and attitude of the speaker) is consciously added in order to supplement or to modify linguistic information, while nonlinguistic information (such as information on the physical states - gender, age, health, etc. - and the mental states - mood, emotion, etc., of the speaker) mostly comes into speech unconsciously, though conscious simulation is possible as in the case of acting. This talk explains the rationale, shows various stages of speech production where these three categories of information comes in, and indicates that message planning and utterance planning are two separate stages; rules of syntax work in the former, while rules of prosody work in the latter.
Hiroya Fujisaki is Professor Emeritus at the University of Tokyo, where he was Professor of Electronic Engineering in the School of Engineering, but also Professor of Speech Science in the Research Institute of Logopedics and Phoniatrics (School of Medicine), and Lecturer in the Dept. of Linguistics (School of Letters). His research interests are in languages, processing of language (both spoken and written) by humans and machines, as well as in human and artificial intelligence, with special emphasis on modeling. His works include a model of language use, a model of the cognitive processes in speech sound identification/discrimination (the "dual channel model"); and a model for the process of fundamental frequency control in speech (the "command-response model", or more often the "Fujisaki model"). Dr. Fujisaki is an honorary member of the International Speech Communication Association (ISCA), an honorary member of the Acoustical Society of Japan, an honorary fellow of the Acoustical Society of India, a fellow of the Acoustical Society of America, a fellow of the Institute of Electronics, Information and Communication Engineers, an inaugural fellow of ISCA, a life member of IEEE and of the Information Processing Society of Japan, a member of the Engineering Academy of Japan, and a corresponding member of the Göttingen Academy of Sciences. He has been serving as Vice President of the Japan-China Science and Technology Association since 2003. Dr. Fujisaki is currently serving as Distinguished Lecturer of ISCA.
