Use of Language in Human Communication – A Model

Abstract: When we use language for information exchange, most of us are not aware of the fact that what is produced in the receiver’s mind as a result of communication is not the same as what was originally in the sender’s mind. This can be clearly and quantitatively demonstrated by the method of experimental psychology and mathematical formulation of experimental results, and indicates the limitations inherent to human communication by language.

Biography: Hiroya Fujisaki is a Professor Emeritus at the University of Tokyo, and is also an honorary member of the International Speech Communication Association (ISCA), an honorary member of the Acoustical Society of Japan (ASJ), an honorary fellow of the Acoustical Society of India, a life member of the Institute of Electrical and Electronics Engineers (IEEE), a fellow of the Acoustical Society of America (ASA) and of the Institute of Electronics, Information and Communication Engineers (IEICE). He has been a Vice President of the Japan-China Science and Technology Exchange Association since 2003. Currently, he is serving as a Distinguished Lecturer of ISCA for 2016 and 2017.

Hiroya Fujisaki was born in 1930, earned his BS, MS and Ph.D. degrees from the University of Tokyo, joined the faculty in 1962, and became professor of Electrical Engineering at the School of Engineering in 1973. He was also professor of speech science at the Research Institute of Logopedics and Phoniatrics, School of Medicine, and lecturer at the Dept. of Linguistics, School of Letters. He was a Fulbright scholar at Massachusetts Institute of Technology (MIT), United States (1958-1961), guest researcher at Royal Institute of Technology (KTH), Sweden (1960), visiting professor at University of Texas, Austin (1980), Royal Institute of Technology, Sweden (1981), University of Goettingen, Germany (1981), Nanjing University, China (1985-1986), University of Science and Technology of China (1987-1991), as well as full professor at the Department of Applied Electronics, Tokyo University of Science, Japan (1991-2001).

His research covers a broad range of topics in speech communication and spoken language processing, natural language processing, human and artificial intelligence, with special emphasis on modeling, including a model of language use, a model for the perceptual processes in speech identification/discrimination (known as the dual channel model); a model for the process of fundamental frequency control in speech (known as the Fujisaki model)..

He served as the Founder Chairman of the Tokyo Chapter of the IEEE Signal Processing Society, and chaired ICASSP-86 in Tokyo, which was the first ICASSP ever held in the Asia-Pacific region. He also played a key role in activating the speech research community of Japan, and in defining and promoting the field of spoken language processing internationally by founding the International Conference on Spoken Language Processing (ICSLP) in 1990, now merged with EUROSPEECH into the INTERSPEECH series. In particular, he served as the honorary chair of INTERSPEECH 2000 in Beijing, China. Also, he successfully led a Japanese National Project on Information Retrieval through Human-Machine Spoken Dialogue, and chaired a series of International Symposia on Spoken Dialogue Systems. In 2000, it was held in Beijing as a satellite of INTERSPEECH 2000.

For his academic works and technical leadership, Professor Fujisaki received a number of awards and honors including the Distinguished Achievement Awards both from the Institute of Electrical Communication Engineers of Japan and the Institute of Electrical Engineers of Japan (1973), the Meritorious Service Award from the IEEE Acoustics, Speech, and Signal Processing Society (1988), and the Special Distinguished Service Award from the Acoustical Society of America (1988) He was named Person of Merit in Science and Technology by the Mayor of Tokyo (1989), and was awarded the Third Millennium Medal from the IEEE (2000), the Medal for Significant Scientific Achievement from ISCA (2008), and the Medal for Exceptional Service also from ISCA (2015).
