Effects of a dynamic F0 on the perceived vowel duration in Japanese

This study examined the effect of a dynamic and a level F0 on the perceived duration in Tokyo Japanese. It was found that a rising F0 as well as a falling F0 affect the perceived vowel duration. Specifically, a falling F0 increases the perceived vowel duration regardless of its position in a word compared to a level F0; on the other hand, a rising F0 shows the same effect only on the word final vowel and it decreases the perceived vowel duration in the word initial syllable.
