The purpose of this study was to investigate the relation between the traditional concept of formant frequencies and the controversial concept of optimal octaves in the perception of the vowels/i, a, u/. The vowels (produced by a male speaker of General American English) were filtered through eight bandwidths (80-160, 160-315, 315-630, 630-1,250, 1,250-2,500, 2,500-5,000, 5,000-10,000, and 10,000-20,000 Hz) and presented to two groups of subjects. One group performed similarity ratings on pairs of filtered and nonfiltered stimuli; the other identified the individual filtered and nonfiltered vowels. The optimal bandwidths derived from the data of the two groups were compared to the formant frequencies of our speaker, to those reported in the literature, and to the optimal octaves published earlier by other authors. The results showed that there were specific bandwidths which allowed for correct perception and identification of each vowel, and that these bandwidths were compatible with both the optimal octaves and the formant frequencies reported in the literature for each vowel.
本研究的目的是调查在元音/i, a, u/的感知中，传统的共振峰频率概念与存在争议的最佳八度概念之间的关系。这些元音（由一位通用美国英语的男性发音者发出）通过八个带宽（80 - 160、160 - 315、315 - 630、630 - 1250、1250 - 2500、2500 - 5000、5000 - 10000和10000 - 20000赫兹）进行滤波，并呈现给两组受试者。一组对滤波后的和未滤波的刺激对进行相似性评级；另一组识别单独的滤波后的和未滤波的元音。将两组数据得出的最佳带宽与我们的发音者的共振峰频率、文献中报道的共振峰频率以及其他作者先前公布的最佳八度进行比较。结果表明，存在特定的带宽能够实现对每个元音的正确感知和识别，并且这些带宽与文献中针对每个元音报道的最佳八度和共振峰频率均相符。
