Variation of Phonation Types Due to Paralinguistic Information: An Analysis of High-Speed Video Images

As part of an effort to examine the transmission mechanism of paralinguistic information as well as phonation variation due to paralinguistic information, laryngeal observation was conducted using high-speed digital video image. The results showed that 'breathy' and 'creaky' phonation was observed for 'disappointment' and 'suspicion' utterances, respectively, while 'modal' phonation was observed for 'neutral' utterances. The phonation types characterizing each paralinguistic meaning were maintained throughout the vowel and consonant portions of the utterance. This fact suggests that the domain of phonation control due to paralinguistic information is the whole utterance. This parallels our previous findings about articulatory control, suggesting that paralinguistic information involves control of voice-quality rather than of individual segments. Acoustic comparison of more extended data is also discussed.
