摘要

语速影响音段的语音实现以及相邻音段发音动作的时间关系，然而对普通话音段产出的影响却并不清楚。该文使用动态电子腭位方法分析语速对普通话跨音节辅音丛/η#C2/中音段发音动作的时间关系以及V1#C2V2中音段的生理和声学特征的影响。研究发现：辅音丛音段发音动作的绝对时差和动作重叠度随语速的加快而增大；音段的生理/声学时长与语速线性相关，语速对辅音动作幅度的影响与辅音发音部位和方式有关；元音动作幅度减弱，在声学上表现出央化的趋势。研究结果表明：普通话语速控制与音段发音动作的时间关系以及音段动作的时空特征有关，音段发音属性和发音人发音策略也影响不同语速条件下的音段产出。

Abstract

The phonetic realization of speech segments and the timing relation of the articulations of contiguous segments vary for different speech rates. How the speech rate affects the segmental articulations in Standard Chinese is still not very understood. This paper studies the effect of the speech rate on the segment production in Standard Chinese using electropalatography to focus on the articulatory timing relation in heterorganic consonant clusters/η#C2/and segment articulations in V1#C2V2. The results show that the absolute latency and the gestural overlap of the consonant clusters increases with faster speech rates. Significant linear relations were found between the articulatory or acoustic length for the segments. Effect of the speech rate on the consonantal displacement depended on the place and manner of the articulation. Gestural weakening of vowels was found accompanied by acoustic centralization. The results indicate that the articulatory mechanisms for the speech rate control are associated with the timing relation of contiguous gestures and the temporal-spatial properties of the segments. The articulatory attributes of consonants and individual strategies also affect the segment production for different speech rates.
