本文报道了一项研究的结果，其中不同元音的共振峰频率的变化进行了检查方面的几个预测来自量子理论的讲话。两名受试者被要求再现八个不同的稳态合成元音，这些元音以随机顺序重复出现。频谱分析进行了声乐的反应，以获得平均值和标准偏差的元音共振峰频率。在量子理论的精神，它被预测，点元音。/i/、/a/和/u/将显示出比非点元音低的标准偏差，因为这些元音被假定产生于声道中的某些位置，在这些位置处，发音中的小扰动仅产生结果共振峰频率的最小变化。也就是说，这些元音被假定为量子元音。这项研究的结果几乎没有为正在考虑的假设提供支持。报告中讨论了结果的结果，并对未能找到量子理论的支持进行了一些推测。最后还提供了几个意见的计算机模拟研究的语音生产和需要额外的经验研究元音生产与真实的谈话者。
This paper reports the results of a study in which variability of formant frequencies for different vowels was examined with regard to several predictions derived from the quantal theory of speech. Two subjects were required to reproduce eight different steady-state synthetic vowels which were presented repeatedly in a randomized order. Spectral analysis was carried out on the vocal responses in order to obtain means and standard deviations of the vowel formant frequencies. In the spirit of the quantal theory, it was predicted that the points vowel. /i/, /a/ and /u/ would show lower standard deviations than the nonpoint vowels because these vowels are assumed to be produced at places in the vocal tract where small perturbations in articulation produce only minimal changes in the resulting formant frequencies. That is, these vowels are assumed to be quantal vowels. The results of this study provided little support for the hypothesis under consideration. A discussion of the outcome of the results as well as some speculation as to its failure to find support for the quantal theory is provided in the report. Several final comments are also offered about computer simulation studies of speech production and the need for additional empirical studies on vowel production with real talkers.
