It is by now well established that during normal conversation talkers often produce large variation in the rate at which they speak. However, existing research suggests that this modification is largely due to changes in the amount of pausing during conversation, and much less to actual changes in articulation rate, that is, the rate at which the speech itself is produced. In an attempt to examine this issue further, we used a modified measurement procedure to reanalyze the speech data from 30 talkers in an interview situation. In contrast to the earlier analyses, we found that there was indeed substantial variation in articulation rate for these speakers, even within a single utterance of a single talker. The implications of these findings for theories of segmental perception and for models of speech planning are discussed.
现在已经充分证实，在正常对话中，说话者说话的语速常常会有很大变化。然而，现有研究表明，这种变化很大程度上是由于对话中停顿量的改变，而与发音速度（即语音本身产生的速度）的实际变化关系较小。为了进一步研究这个问题，我们使用了一种改进的测量方法，对采访情境中30名说话者的语音数据进行重新分析。与早期分析不同的是，我们发现这些说话者的发音速度确实存在很大差异，即使在单个说话者的单个话语中也是如此。我们还讨论了这些发现对音段感知理论和言语计划模型的意义。
