系列讲座1（APSIPA Distinguished Lecturer Talk）：
Making speech tangible: for better understanding of human speech communication
摘要：This talk presents underlying concept, technologies and applications of STRAIGHT, a framework for speech analysis, modification and resynthesis, which was originally designed to facilitate speech perception research. The talk also introduces recent advances which may provide new possible strategies in speech communication research. One is "Temporally variable multi-aspect morphing of arbitrarily many voices." The other is "SparkNG: Speech Production and Auditory perception Research Kernel the Next Generation." Speech plays essential roles in human communication by providing rich side information channels which modify/expand linguistic contents. While recent resurgence of machine learning technologies made speech-based communication with smart machines practical and popular, these rich side information channels which make speech unique are not well explored. It is crucially important to make smart machines to share common basis with humans of these rich side information channels based on deep understanding of human speech communication. "Making speech tangible" by introducing tools which enable quantitative and precise as well as intuitive/direct manipulation of speech parameters, I hope, leads to better understanding of human speech communication.

Biography of Prof. Hideki Kawahara
Hideki Kawahara was given professor emeritus from Wakayama University Japan in April 2015. He had been a professor there from 1997 to 2015. He also was a visiting research scientist of Google UK from August 2015 to June 2016. He is known as the inventor of a speech analysis, modification and synthesis framework STRAIGHT, which is widely used in speech related research fields, since its introduction in 1997. He received Bachelor of Eng., Master of Eng. and Ph.D. in Electrical Engineering from Hokkaido University, Sapporo Japan, in 1972, 1974 and 1977 respectively. In 1977, he joined the Musashino Electrical Communications Laboratories (ECL) of Nippon telegraph and telephone public corporation (later NTT Basic Research Laboratories), Tokyo, Japan. Where, he participated in telephone transmission quality research and later in auditory perception research. In 1992, he joined Human Information Processing Research Laboratories of Advanced Telecommunication Research institute international (HIP-ATR), Kyoto, Japan as a department head, where he promoted research on interactions between speech perception and production. In 1997, he joined Wakayama University as a professor and started the “Auditory Brain” project as the PI of CREST research initiative by JST, where he developed the first implementation of STRAIGHT. He also served to promote academic activities. From 2008 to 2011, he served as a committee member of the Speech and Language Processing committee of the IEEE Signal Processing Society. In 2010 he chaired the Kansai chapter of the Acoustical Society of Japan. He organized many workshops and also served as reviewers and program committee chairs and members of numerous international conferences. He received the best paper award of 1998-1999 EURASIP on underlying principle of STRAIGHT. His research interests are signal processing base on auditory representations, speech perception models and interactive tools for research and education of speech science.
