Title: On the Unreleased Stops in Taiwanese Southern Min
Date/Time: Monday, May 8, 5:00–6:30pm
Location: 32-124

Unreleased stops, lacking a burst, have been claimed to have low perceptibility and are more likely to neutralize place contrasts (Stevens 1994; Ohala 2001), which has been supported by examining no-burst VC fragments spliced from released stops. The common consensus is that stop perception relies on two sources of acoustic cues: (i) formant transition and (ii) spectral frequency of burst noise. It is clear that the latter cue is absent in unreleased stops, and therefore the hypothesis is that the cues of formant transition will be enhanced. This study investigates the acoustic correlates of VC (where C=unreleased stops p̚, t̚, k̚) in Taiwanese Southern Min. We argue that the cues of VC are not totally diminished or undistinguishable. Moreover, different morphoprosodic structures (VC-V vs. VC#V vs. VC#C) further complicate the dispersion of stop contrasts in this study, which will also be discussed in this talk. A further comparison of stop cues exhibits that the coronal and dorsal are contrastive in terms of vowel duration and quality. This may be related to the asymmetrical behaviors of consonant-to-consonant assimilation in several languages (e.g. English and Korean) and diachronic changes of stop contrasts in Chinese Phonology.
