Perceptual features of consonants were investigated from normally-hearing Ss' confusions of stimuli perceived through one-third-octave bands; 12 Ss were paid to respond to CVs consisting of 17 consonants, each paired with the vowels /i, a, u/ and filtered through one-third-octave bands centered at 0.5, 1, 2, 3.15 and 4 kc/s and one critical band (500 c/s wide) centered at 3.15 kc/s. An earlier cursory analysis of distinctive features in these data (Chari, N.C.A., Herman, G. and Danhauer, J.L. "Perception of one-third octave-band filtered speech." J. Acoust. Soc. Am., 1977, 61, 576-580) showed that while place features were severely affected by the filtering, manner and voicing features were not. The data were submitted in the present study to INDSCAL for a more a-posteriori investigation of the features and their weights by the Ss. Results showed some differences in the features and their weights across the various filter bands, but that they were similar to those found earlier for hearing-impaired Ss having losses corresponding to frequency cut-offs in this study.
通过对听力正常的受试者在通过1/3倍频程带感知的刺激中的混淆情况，研究了辅音的感知特征；12名受试者参与实验，对由17个辅音组成的CV音节做出反应，每个辅音分别与元音/i、a、u/配对，并通过中心频率为0.5、1、2、3.15和4千赫兹的1/3倍频程带以及一个中心频率为3.15千赫兹、带宽为500赫兹的临界频带进行滤波。对这些数据中区别特征的早期粗略分析（查里，N.C.A.，赫尔曼，G.和丹豪尔，J.L.《1/3倍频程带滤波语音的感知》。《美国声学学会杂志》，1977年，61卷，576 - 580页）表明，虽然位置特征受到滤波的严重影响，但发音方法和浊音特征不受影响。在本研究中，将这些数据提交给INDSCAL，以便对受试者的特征及其权重进行更具事后性的调查。结果表明，各滤波频带在特征及其权重方面存在一些差异，但与本研究中听力损失对应于频率截止的早期听力受损受试者所发现的情况相似。
