Judges using the Wilson Voice Profile rated the voice quality of 14 noninstitutionalized, 7- to 10-year-old Down syndrome children and a group of nonretarded children. The Down syndrome children received ratings different from the nonretarded children on the Severity subscale of the Wilson Voice Profile. Voice samples were analyzed acoustically in terms of fundamental frequency, fundamental frequency range, frequency and amplitude perturbations, and spectral noise-to-harmonic component ratios. Frequency perturbations, amplitude perturbations, and spectral noise-to-harmonic component ratios were significantly greater for the Down syndrome children. There were also significant correlations between judges' Severity ratings and frequency perturbation levels, amplitude perturbations levels, and spectral noise-to-harmonic component ratios.
使用威尔逊嗓音剖析的评判者对14名7至10岁非收容机构的唐氏综合征儿童以及一组发育正常儿童的嗓音质量进行了评定。在威尔逊嗓音剖析的严重程度子量表上，唐氏综合征儿童得到的评分与发育正常儿童不同。从基频、基频范围、频率和幅度扰动以及频谱噪声与谐波成分比方面对嗓音样本进行了声学分析。唐氏综合征儿童的频率扰动、幅度扰动以及频谱噪声与谐波成分比显著更高。评判者的严重程度评分与频率扰动水平、幅度扰动水平以及频谱噪声与谐波成分比之间也存在显著相关性。
