This study examines the distribution of creaky voice as a function of various prosodic structures in a large-scale corpus of continuous speech of Mandarin. Both tonal categories and prosodic boundaries have strong effects on the likelihood of creak and relative creakiness. It was found that (1) creaky voice in Mandarin is indeed largely driven by the occurrence of low pitch and weakening; (2) Tone 3 sandhi and Tone 2 are different in both pitch and voice quality; (3) the creakiness of Tone 3 (low tone) and the neutral tone (weakening) is realized differently. Moreover, females and males do not differ in how they use creaky voice linguistically.
本研究考察了在大规模的普通话连续语音语料库中，各种韵律结构对摩擦音分布的影响。音高类别和韵律边界对摩擦音出现的可能性和相对摩擦音强度都有很强的影响。研究发现：（1）普通话中的摩擦音主要受低音高和弱化的影响；（2）连读变调的第三声和第二声在音高和音质上是不同的；（3）第三声（低音）和轻声（弱化）的摩擦音强度实现方式不同。此外，女性和男性在语言上使用摩擦音的方式没有差异。
