本研究采用12对极性相反的形容词，运用语义区分技术研究了病理嗓音与正常嗓音的分类标准。通过D-方法和最大似然法从数据中提取的因素与基频、频率扰动商和振幅扰动商相关。研究了9名正常人和15名病理受试者的发音以及9个合成元音样本。第一个因素与音质评价有关，也与振幅扰动密切相关。第二和第三个因素分别与刺激的强度和基频有关。除这三个主要因素外，其他一些次要因素也可能与病理嗓音的区分有关。
Perceptual criteria for classifying pathologic voices in comparison with normal voices were studied with the use of the semantic differential technique using 12 pairs of polar-opposite adjectives. The factors extracted from the data by means of the D-method and of the maximum likelihood method were correlated to fundamental frequency, a frequency perturbation quotient, and an amplitude perturbation quotient. The utterances produced by 9 normal and 15 pathologic subjects together with 9 synthesized vowel samples were investigated. The fisrt factor was related to evaluation of voice quality and was also closely related to the amplitude perturbation. The second and the third factors were associated with intensity and fundamental frequency of the stimuli, respectively. Some minor factors other than the three dominant factors were also supposed to be relevant to the distinction of pathologic voices.
