Abstract as per original application
This project seeks to investigate the relationship between tongue movement and tone in speech production – two parts of articulation formerly considered independent from each other. Although tone is produced by controlling vocal cord tension, a recent study on Swedish (Svensson Lundmark et al., 2021 [Phonetica 78:515–569]) has shown that pitch can affect tongue movement at the same time. We plan to extend this new line of research by looking at consonant-vowel coordination in Cantonese and Mandarin, two languages with respectively six and four lexical tones, under different tone and speech rate conditions. Both acoustic (formant) and articulatory (high temporal resolution ultrasound tongue imaging) data will be collected for analysis, followed by analysis-by-synthesis using VocalTractLab. Our findings will shed new lights on (i) our understanding of speech production, (ii) individual differences in articulatory control, and demonstrate (iii) the use of articulatory synthesis as a convenient tool for hypothesis-testing in articulation research.
本項目旨在研究言語產生過程中舌頭運動和聲調之間的關係——這兩個發音部位從前被認爲是相互獨立的。雖然聲調是通過控制聲帶張力產生的,但最近一項關於瑞典語的研究(Svensson Lundmark等,2021 [Phonetica 78:515-569])表明,音高(pitch)還可以同時影響舌頭的運動。我們計劃在不同的聲調和語速條件下,通過研究粵語和普通話(分別有六個和四個聲調)輔音-元音的協同發音,來擴展這一新的研究思路。我們將收集聲學(共振峰)和發音(高時間分辨率超聲舌部成像)數據進行分析,然後使用VocalTractLab進行分析合成(analysis-by-synthesis)。我們的研究結果將有助於:(i) 深化我們對言語產生的理解;(ii) 揭示發音控制的個體差異;並證明(iii)發音器官參數合成是發音研究中假設檢驗(hypothesis-testing)的有效工具。
