 note = {声道長の縮小や拡大を模して，スペクトル包絡の周波数軸を伸長圧縮した声質変換音声では，基本周波数 (fo) の高低関係と声の高さの印象評価が逆転することがある．このピッチ感の錯覚が起こる条件の精査をするため，標準抑揚，平坦抑揚，逆相抑揚，疑似歌声，疑似ささやき声による評価実験を行った．, When the speech is converted by expansion and compression of the fundamental frequency axis of spectrum envelopes simulating reduction and expansion of vocal tract length, the timbre of the voice changes systematically. In the converted voice, a reversal of the relationship between height of fundamental frequency and impression of voice pitch is often observed. In order to examine the conditions that cause this voice pitch illusion, evaluation experiments were conducted using standard intonation, flat intonation, antiphase intonation, quasi singing-voice, and quasi whisper.},
