일본어 어중 파열음의 음성학적 특징

Acoustic characteristics for Japanese stops.

In this paper, I investigated acoustic characteristics of Japanese Stops. Japanese stops (/b.p.d.t.g.k/) are examined from V₁C₂V₂ㆍV₁QC₂V₂sequence with low-high pitch. Especially, I have analyzed Voice Onset Time (Van, Closure Duration (CD) of the target stops, Pitch, Duration and Intensity of the neighbouring segments. Closure duration would be longer if geminated stops were placed in a word with a low-high pitch because the speaker needs more time to tense his vocal folds. Temporal aspects of the neighbouring segments appear to be influenced by the stop. In a geminated stops, the duration of the preceding/following vowel tends to be shorter when a stop has longer closure duration.
