Profile

Shigeki Sagayama was born in Hyogo, Japan, in 1948. He received the B.E., M.E., and Ph.D. degrees from the University of Tokyo, Tokyo, Japan, in 1972, 1974, and 1998, respectively, all in mathematical engineering and information physics.

He joined Nippon Telegraph and Telephone Public Corporation (currently, NTT) in 1974 and started his career in speech analysis, synthesis, and recognition at NTT Laboratories, Musashino, Japan. From 1990 to 1993, he was Head of Speech Processing Department, ATR Interpreting Telephony Laboratories, Kyoto, Japan, pursuing an automatic speech translation project. From 1993 to 1998, he was responsible for speech recognition, synthesis, and dialog systems at NTT Human Interface Laboratories, Yokosuka, Japan. In 1998, he became a Professor of the Graduate School of Information Science, Japan Advanced Institute of Science and Technology (JAIST), Ishikawa, Japan. In 2000, he was appointed Professor of the Graduate School of Information Science and Technology (formerly Graduate School of Engineering), University of Tokyo (UT), Tokyo, Japan. In 2013, he became a professor emeritus of UT and Project Professor at National Institute of informatics (NII), Tokyo, Japan. In 2014, he became a full professor at Meiji University, School of Interdisciplinary Mathematical Sciences, Nakano, Tokyo. His major research Interests include processing and recognition of speech, music, acoustic signals, handwriting, and images. He was the leader of anthropomorphic spoken dialog agent project (Galatea Project) from 2000 to 2003.

He is known as one of pioneers of numerous important concepts in speech processing including Lag Window (1975) widely used in speech codecs, cepstrum-based speech recognition later deployed in first spoken dialog system in public telephone service ("ANSER") in 1981, Delta-Cepstrum (1979) which became essential in speech recognition, statistical speech synthesis (1997) related to modern HMM-based speech synthesis, Tree-based Allophone Clustering (1986) before K-F Lee et al.’s phonetical tree-based allophone clustering, Hidden Markov Network (1991) for precise modeling of allophonic variations currently employed in a NTT DoCoMo’s mobile phone service, Vector Field Smoothing (1990) for speaker adaptation which became one of major methods of speaker adaptation before MLLR was proposed, Tree-structured Speaker Modeling (1992), Jacobian Adaptation (1996?) for rapid environmental noise in speech recognition, and many others. He also promoted stroke-HMM-based online handwritten Kanji character recognition (1999), Anthropomorphic Spoken Dialog System (2001) combining speech recognition, synthesis, face expression generation and dialog control with 10 research institutes, early (probably first) use of Hidden Markov Model (1999) in music processing, automatic music composition from Japanese lyrics (2006), and many others.

Prof. Sagayama is a Fellow of IEICEJ, a life member of IEEE, and a menber of the Acoustical Society of Japan (ASJ) and IPSJ. He received the National Invention Award from the Institute of Invention of Japan in 1991, the Chief Official’s award for Research Achievement from the Science and Technology Agency of Japan in 1996, and other academic awards including Paper Awards from the Institute of Electronics, Information, and Communications Engineers (IEICEJ) Japan, in 1996 and from the Information Processing Society of Japan (IPSJ) in 1995.

In order to transcribe scores from the polyphonic acoustic signals, we propose a generative model consisting following two processes; (1) generating score by using 2-dimentional tree structure, and (2) generating spectrograms from the score. We al...

In this paper, we tackle to fit parameters of MIDI signals such as velocities and onset times to recorded polyphonic signals, which are performed with reference of the corresponding score. The large gap between MIDI parameters and acoustic signals...

We have previously proposed a statistical model of speech F0 contours, which is based on the discrete-time version of the Fujisaki model. One advantage of this model is that it allows us to introduce statistical methods to learn the Fujisaki-model...

The Short-Time Fourier Transform (STFT) is commonly used as a back-end to multipitch analysis and it transforms acoustic signals into the time-frequency representation. However, a trade-off between time and frequency resolutions exists, depending ...

Context-dependent HMM is commonly used in speech recognition. The model can be realized by two ways : context clustering or tied-mixuture. In speech recognition, the former is reported to be more efficient. However, there is some difficulty in app...
