| Research Abstract |
The results of phonatory study revealed that the glottal opening of stop consonants is suppressed at its beginning part. This finding supports the claims that sokuon involves glottal tension (Hattori 1984) or laryngealization (Fujimura 2007) in its first half. However, MRI study has shown that the tongue tends to rise later during sokuon than its single counterpart. This suggests that the suppression of the glottal opening during sokuon is not due to the earlier closure for the consonants at the vocal tract. Acoustic analyses revealed that, at Miyakojima dialect in Okinawa, laryngealization and nasalization are involved during word initial sokuon, and the timing control for geminates in Italian differs from that is sokuon, which indicate that the dialectal variation as well as the inter-language variation are significant with regards sokuon, or geminates.
