This article examines how speech rate increase acts to articulatorily change the movements of the jaw gesture. The EMA and acoustic experiments with two subjects have corroborated some previous findings, as follows: a) acceleration duration decrease from slow to fast rate; b) peak/valley velocity (modulus) decrease from slow to fast rate; c) gestural duration decrease from slow to fast rate; and d) constant proportional time-to-peak/valley-velocity from slow to fast rate. The hypotheses of y-extremum decrease from slow to fast rate and constriction displacement decrease from slow to fast rate were not statistically significant, and, therefore, need further experiments.

本文研究了语速增加如何以发音方式改变下巴手势的运动。EMA 和两个受试者的声学实验证实了之前的一些发现，如下所示： a) 加速持续时间从慢速减少到快速；b) 峰/谷速度（模量）从慢速下降到快速；c) 手势持续时间从慢到快减少；d) 从慢速到快速的恒定比例的峰值时间/谷速。y 极值从慢到快减少和收缩位移从慢到快减少的假设在统计上不显着，因此需要进一步的实验。
