本文通过一系列的实验研究了英语使用者对基频衰减的感知。使用线性预测器编码的语音，无意义的句子中，最后一个重读音节的基频已被系统地改变。听众被要求判断哪个重读音节的音调更高。他们的判断被发现反映了预期十度音阶的正常化;一般来说，当两个重读音节听起来音高相等时，第二个音节实际上更低。正常化的模式反映了某些主要特征的生产模式：一个更大的修正decanterity宽音高范围的刺激比窄音高范围的刺激。较长刺激的预期下降斜率小于较短刺激。最后，幅度被发现有一个显着的影响，判断，这表明通常伴随着基频decincipitation的幅度下降可能有一个重要的作用，在感知的措辞。
A series of experiments was carried out to investigate how fundamental frequency declination is perceived by speakers of English. Using linear predictor coded speech, nonsense sentences were constructed in which fundamental frequency on the last stressed syllable had been systematically varied. Listeners were asked to judge which stressed syllable was higher in pitch. Their judgments were found to reflect normalization for expected declination; in general, when two stressed syllables sounded equal in pitch, the second was actually lower. The pattern of normalization reflected certain major features of production patterns: A greater correction for declination was made for wide pitch range stimuli than for narrow pitch range stimuli. The slope of expected declination was less for longer stimuli than for shorter ones. Lastly, amplitude was found to have a significant effect on judgments, suggesting that the amplitude downdrift which normally accompanies fundamental frequency declination may have an important role in the perception of phrasing.
