Mismatches between the production and perception of Japanese pitch accent

这项研究调查了东京-日本音口音是否有基频(=F0)以外的声学提示。使用数据库确定了具有相对较高熟悉度的最少的末尾重音和非重音单词对。这两种类型的词在完全元音清音的频率或词尾变化的持续时间方面没有可靠的差异。一项感知研究目前正在进行中，该研究考察了口音与口音时长之外的其他口音的声学相关性。

This research investigated if Tokyo-Japanese pitch accent has an acoustic cue other than the fundamental frequency (=F0). Minimal pairs of final-accented and unaccented words that had relatively high familiarity ratings were identified using a database. The two types of words did not differ reliably in terms of the frequencies of the complete vowel devoicing or the durations of the word-final moras. A perception study that examines an acoustic correlate of accent other than the FO and duration is currently underway.
