In acoustic theory, formant pattern differences within one vowel identify are related to differences in the speaker groups or in the types of vocalization. Yet, studies of vowel synthesis indicate that formant patterns can also vary strongly in relation either to pitch or to formant number alterations. Within this study, natural vocalizations of nine German vowels were investigated with regard to different formant patterns representing the same vowel identity, apart from differences in speaker groups and vocalization types. The results show i) FO-dependence of the lower formants < 1.5-2 kHz; ii) occurrence of natural one-formant back and two-formant front vowels; iii) a non-systematic relationship between FO and the formants, and a non-systematic relationship between formant patterns of different formant numbers. The implications for psychophysics, physiology and perception of speech are discussed.
在声学理论中，同一元音识别中的共振峰模式差异与说话者群体的差异或发声类型的差异有关。然而，元音合成研究表明，共振峰模式也可能因音高或共振峰数量变化而有很大差异。在本研究中，除了说话者群体和发声类型的差异外，还研究了九个德语元音的自然发声中代表相同元音识别的不同共振峰模式。结果表明：i）低于1.5 - 2 kHz的低频共振峰对基频的依赖性；ii）自然出现的单共振峰后元音和双共振峰前元音；iii）基频与共振峰之间的非系统关系，以及不同共振峰数量的共振峰模式之间的非系统关系。文中还讨论了这些结果对语音心理物理学、生理学和感知的影响。
