I will highlight this talk with some examples of my research into speech prosody over nearly the past 50 years. Starting from an acoustic, physiological, and perceptual perspective, F0 contours were extracted from several hundreds of words of both Tokyo and Osaka dialects for a study of Japanese word accent. The durations of pauses and F0 contours in formal newscasts and casual conversations were investigated. This work resulted in tools both for study and for education; for example the "CD-ROM Osaka-Tokyo Accent Speech Dictionary" and the "SUGI Speech Analyzer" were produced and made available. Three CD-ROMs for phonetic science and acoustic education were also produced recently. The Speech Database collected as part of the national research project "Japanese Prosody and its Education" (funded by the Ministry of Education and Science, 1989-1993) included speech data from all Japanese dialectal regions, resulted in a corpus of thirty-six DVD are to be released in April, 2004.
