听众根据四种声音类型对49个元音/a/和/i/样本进行分类：嘶哑，呼吸，紧张和正常。元音进行了声学分析，平均谐波/噪声的差异，在四个频谱区域，平均基频，基频的自然对数，和抖动。判别分析表明，使用三个声学参数进行语音类型分类的准确率为80%：（a）平均谐波/噪声差因子（1-3.5 kHz），（B）基频的自然对数，和（c）元音类型。这些特定的声学参数的感知和分类的声音类型的意义进行了讨论。
Listeners classified 49 samples of vowels /a/ and /i/ on the basis of four voice types: hoarse, breathy, strained, and normal. The vowels were analyzed acoustically for mean harmonic/noise differences in four spectral regions, average fundamental frequency, natural logarithm of fundamental frequency, and jitter. Discriminant analysis showed that classifications of voice type were made with 80% accuracy using three acoustic parameters: (a) mean harmonic/noise difference factor (1–3.5 kHz), (b) natural log of fundamental frequency, and (c) vowel type. The significance of these particular acoustic parameters for the perception and classification of voice types is discussed.
