Twenty adult males, presenting laryngeal pathology, each produced five vowels and two sentences for tape recording. Individual recordings were then rated for roughness on a 5-point equal-appearing intervals scale. Each vowel production was also analyzed spectrographically. High, positive correlations (multiple r) were obtained between vowel spectral noise measures (dB SPL) and median roughness ratings for the vowels and sentences. The findings, similar to those previously reported for subjects without pathology, suggest that the relationships shown are independent of laryngeal health. Vowel spectral noise measures appear to provide a useful quantitative index of vocal roughness in vowels and connected speech.
二十名患有喉部病变的成年男性，每人发出五个元音和两个句子进行录音。然后，根据五点等距量表对个体录音的粗糙度进行评分。每个元音发音还通过频谱分析进行了分析。在元音频谱噪声测量值（dB SPL）与元音和句子的粗糙度中位数评分之间获得了高度正相关（多重相关系数r）。这些发现与之前针对无病变受试者的报告结果相似，表明所显示的关系与喉部健康无关。元音频谱噪声测量似乎为元音和连贯语音中的嗓音粗糙度提供了一个有用的定量指标。
