Research Abstract	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.
