On April 18th and April 25th we will hear two Masters thesis presentations from Yiming Gu and Haoru Zhang.
Yiming Gu: Tone Sandhi in Ganyu Mandarin
Tone sandhi in Ganyu, a Mandarin dialect, is relatively complicated. There were only a few descriptive works in existing literature. By using prosodic structure, the thesis provides a uniform explanation to non-focused pitched syllable tone sandhi in Ganyu from the perspective of Optimality Theory. In the analysis, a syllable contains three pitch targets underlyingly, while in the output only two targets are allowed. Phonological phrase and foot are constructed via the ranking of phonosyntactic constraints. Pitch-sensitive constraints which are responsible for each and every sandhi phenomenon are motivated by tonal saliency, metrical integrity, target realizability, and pitch faithfulness. In addition, the thesis proposes a new concept: dependent pitch target. Phonologically-relevant creaky or falsetto sounds, as found in Ganyu and neighboring dialects, are dependent pitch targets which must follow a low or high target, and they are very shot in duration. The analysis covers disyllabic and trisyllabic feet both at the final position of a phonological phrase and at the non-final position. The analysis can be extended to cases which involve focus-stressed syllables and pitch-less syllables in future investigations.
Haoru Zhang: Phonetic Convergence in Mandarin
Phonetic convergence is the phenomenon that speakers’ acoustic and phonetic characteristics increase in similarity with each others’ during communication. This phenomenon has been gaining increasing interest over recent years, and many measures have been claimed to be subjected to convergence, such as fundamental frequency (F0), formants, VOT, duration, etc. The current study contributes to the field by investigating these measures on Mandarin, a tonal language. The results reveal potential differences in sensitivity to convergence across measures, especially among tone-related variables.
