The rate of speaking in words per minute is a function of three independent variables, namely, articulation rate and the number and durations of pauses. The present study varies each of these components separately in a factorial design in order to determine how the listener combines them into a global impression of speech rate. A model was obtained by direct scaling and linear regression that accounts reasonably well for the estimates of apparent rate obtained in this and several other studies. It provides for a trading relation between articulation rate and pause rate in which the former is much more influential in determining the listener's perception of speech rate.
每分钟的言语表达速率是三个独立变量的函数，即清晰度速率以及停顿的次数和时长。本研究在析因设计中分别改变这些组成部分中的每一个，以确定听众如何将它们综合成言语速率的整体印象。通过直接标度和线性回归得到了一个模型，该模型能较好地解释在本研究及其他几项研究中获得的表观速率估计值。它提供了清晰度速率和停顿速率之间的一种权衡关系，其中前者在决定听众对言语速率的感知方面更具影响力。
