INTERSPEECH 2004 - ICSLP
We investigated V-V hiatus through J-ToBI labeling and listening to whole phrases to estimate degree of discontinuity and to determine the exact boundary between two phrases if possible. Appropriate boundaries were found in most cases as the maximum perceptual score. Using electroglottography (EGG) and spectrogram, the acoustic phonological feature of these V-V hiatus was phrase-initial glottalization and phrase final nasalization observable in EGG and spectrogram, as well as phrase-final lengthening and phrase-initial shortening. The test materials are taken from the "Japanese MULTEXT", consisting of a particle - vowel (36), adjective - vowel (5), and word - word (4).
