| Outline of Final Research Achievements |
This research focused on the use of creaky voice in Wuming Zhuang, finding that a pair of tones involve a creaky-modal phonation contrast. It also introduced a new tool, psychoacoustic roughness, which was found to more reliably identify creakiness in creaky and checked tones in Burmese. Other measures, such as the Covarep algorithm which relies on spectral measures, did not accurately predict creaky tones in Burmese. Finally, a triad of perception experiments were performed on Wuming Zhuang speakers to assess whether and to what extent they use creakiness, F0 and duration in distinguishing contrastive tones.
