本研究的目的是考察在实际语速的三个水平上，发声频率和发声强度对语速知觉的影响。一个自发语音的样本被电子变化以产生9个刺激片段，这些刺激片段将每个声音频率和强度的三个水平进行因子组合。九个刺激被记录下来，因此在每个刺激之前是原始片段，该原始片段作为九个刺激中的每一个被比较的标准。然后，9个刺激对的集合的语音速率被电子改变，以获得慢集合、中等集合和快集合，尽管三个集合中每个片段的持续时间为20秒。这些集合由不同的评委小组根据四个7分量表进行评级，这些7分量表衡量的是感知语速、音调、响度和感知时长。结果表明，在三种实际语速下，对语速的感知都与发声频率和强度呈正相关，并表明这些关系是在自发产生的语音中几乎总是听到这样的协变的重复经验的函数。
The purpose of the study was to investigate the influence of vocal frequency and vocal intensity upon the perception of speech rate at three levels of actual speech rate. A single sample of spontaneous speech was electronically varied to produce nine stimulus segments that factorially combined three levels each of vocal frequency and intensity. The nine stimuli were recorded such that preceding each was the original segment that served as the standard with which each of the nine stimuli was to be compared. The speech rate of the set of nine stimulus pairs was then electronically altered to obtain a slow set, a moderate set, and a fast set, although the duration of every segment in the three sets was 20 seconds. The sets were rated by different groups of judges in terms of four 7-point scales that measured perceived speech rate, pitch, loudness, and perceived duration. The results indicate that the perception of speech rate is positively related to vocal frequency and intensity at each of the three actual speech rates, and suggest that these relationships are a function of the repeated experience of almost always hearing such covariation in spontaneously occurring speech.
