本文研究了藏族侨民所说的藏语中辅音和元音发音的相对时间。根据发音计时的耦合振荡器模型（Browman & Goldstein 2000，Nam & Saltzman 2003），手势之间最容易获得的耦合模式是同相（同步）或反相（顺序）计时，这些模式之间的竞争也产生了稳定的计时模式。该模型预测其他时序关系，即“偏心时序”，是可能的，但并不那么容易获得。使用电磁关节描记术 (EMA) 收集的数据显示相对 C-V 时序与竞争耦合或偏心时序一致。竞争耦合是对声调语言中 CV 音节的合理解释（Gao 2008），但声学分析表明，某些说话者不会产生与声调相对应的音高对比。由于明显没有音调手势，我们得出结论，这些扬声器表现出偏心的 C-V 时序。
This paper investigates the relative timing of onset consonant and vowel gestures in Tibetan as spoken in the Tibetan diaspora. According to the coupled oscillator model of articulatory timing (Browman & Goldstein 2000, Nam & Saltzman 2003), the most readily-available coupling modes among gestures are in-phase (synchronous) or anti-phase (sequential) timing, with competition among these modes also giving rise to a stable timing pattern. The model predicts that other timing relations, i.e. ”eccentric timing”, are possible but not as readily available. Data gathered using electromagnetic articulography (EMA) shows relative C-V timing consistent with either competitive coupling or eccentric timing. Competitive coupling is a plausible explanation for CV syllables in a tone language (Gao 2008), but acoustic analysis showed that some speakers do not produce a pitch contrast corresponding to tone. In the apparent absence of a tone gesture, we conclude that these speakers exhibit eccentric C-V timing.
