Listeners matched the pitch of 36 clear to severely dysphonic vowels to the frequency of pure tones produced by a signal generator. Mean difference scores on pitch match correlated-.56 with jitter, -51 with jitter ratio, -.57 with spectrographic noise classifications, and -.64 with vocal roughness. Moderately to severely dysphonic vowels received significantly lower pitch match values than clear to mildly dysphonic vowels. Findings suggest that the effect of vocal roughness on pitch should be considered by the clinician who makes use of perceptual judgments.
听众将36个清晰至严重发音障碍的元音音高与信号发生器产生的纯音频率相匹配。音高匹配的平均差异分数与抖动的相关性为-0.56，与抖动比率的相关性为-0.51，与频谱噪声分类的相关性为-0.57，与嗓音粗糙度的相关性为-0.64。中度至重度发音障碍的元音的音高匹配值明显低于清晰至轻度发音障碍的元音。研究结果表明，利用感知判断的临床医生应考虑嗓音粗糙度对音高的影响。
