Paralinguistic Effects on Voice Quality: A Study in Japanese
نویسندگان
چکیده
This study analyzes two spectral properties in vowel segments, H1-H2 (related to glottal opening) and H1-A3 (related to the speed of vocal fold closing gesture) in an attempt to infer the voice quality variation associated with different types of paralinguistic information (PI) types. Results suggest that both glottal opening and closing speed of the glottis differ significantly depending on PI. However, for some PI types there were also significant syllable effects. The correlation between F0 and these two voice parameters was very low leading to the conclusion that just F0 differences cannot account for the observed voice quality variation. Significant differences were also noted for the power of speech waveform (RMS) according to PI. Inter-speaker variation was noted especially for ‘suspicion’.

Extraction of paralinguistic information carried by mono-syllabic interjections in Japanese
Mono-syllabic interjections are often used to express a reaction in conversational speech. It is known that there is relationship between the speaking style, given by intonation and voice quality-related prosodic features, and the paralinguistic information carried by an interjection. However, it is also known that this relationship is dependent on the interjection type. In the present work, we...
متن کاملPhonetic and phonological characteristics of paralinguistic information in spoken Japanese
Six paralinguistic information types uttered by three subjects were examined. Considerable changes were observed in duration, pitch, vowel formant, and voice quality. These findings require some reconsideration of the problems in the phrase phonology of Japanese like mora-based timing and phrase-initial pitch movement. On the other hand, lexically specified phonological features were more robus...

This paper describes a study of speaking-style characteristics, or “tone-of-voice”, in conversational speech, and shows that non-verbal information is transmitted efficiently regardless of cultural and linguistic contexts through differences in prosodic and voice-quality features. We asked Korean and American listeners with no previous kowledge of Japanese to judge the meaning of various uttera...

“Rikimi” is a “pressed-type” voice quality that appears in Japanese conversational speech for expressing paralinguistic information related to emotional or attitudinal behaviors of the speaker. We conducted acoustic, electroglottographic (EGG) and paralinguistic analyses on speech segments including “rikimi”, extracted from spontaneous dialogue speech data. “Rikimi” may be accompanied by severa...
