Further analyses have been made on readings of two scripts by six talkers [T. H. Crystal and A. S. House, J. Acoust. Soc. Am. 72, 705-716 (1982); 84, 1932-1935 (1988); 83, 1553-1573 (1988)]. Durations of syllables and stress groups are compared to earlier data and various pertinent published reports, and are used to evaluate reports of articulation rate variability. The average durations of syllables of different complexity have a quasilinear dependency on the number of phones in the syllable, where the linear factor and the vowel durations are functions of stress. The duration of stress groups has a quasilinear dependency on the number of syllables and the number of phones. It was found that variability of articulation rate, measured as the average syllable duration for interpause intervals (runs), is not random, but is the natural consequence of the content of the run. Durations of comparable runs of different talkers are highly correlated. Major determinants of average syllable duration are the average number of phones per syllable and the proportion of either + stress phones or + stress syllables in the run.
针对六位讲话者对两份文稿的读数进行了进一步分析[T. H. 克里斯托和A. S. 豪斯，《美国声学学会杂志》72, 705 - 716 (1982); 84, 1932 - 1935 (1988); 83, 1553 - 1573 (1988)]。将音节和重音组的时长与早期数据及各种相关已发表报告进行比较，并用于评估发音速率变异性的报告。不同复杂程度音节的平均时长与音节中音素的数量呈准线性相关，其中线性因子和元音时长是重音的函数。重音组的时长与音节数量和音素数量呈准线性相关。研究发现，以停顿间隔（语流）的平均音节时长来衡量的发音速率变异性并非随机的，而是语流内容的自然结果。不同讲话者可比语流的时长高度相关。平均音节时长的主要决定因素是每个音节的平均音素数量以及语流中重读元音或重读音节的比例。
