该报告调查了受过训练的听众的声学参数与声音嘶哑感知之间的相关性。持续元音和连接语音都被检查了。测量了来自持续元音样本的 14 个声学参数和来自连接语音的 2 个声学参数。结果表明，抖动、闪烁和倒谱峰突出度 (CPP) 与持续元音中的嘶哑感觉相关。 CPP 与连线语音中的声音嘶哑感知密切相关。一些证据表明，对连贯语音中的声音嘶哑的感知比对持续元音中的声音嘶哑的感知更有效。结论是，与抖动、闪烁或持续元音的 CPP 相比，连接语音的 CPP 是更有效的客观嘶哑测量，并且在连接语音而不是孤立元音中，对嘶哑的感知可能是最准确的。版权所有 (C) 2004 S. Karger AG，巴塞尔。
This report investigates the correlations between acoustic parameters and the perception of hoarseness by trained listeners. Both sustained vowels and connected speech were examined. Fourteen acoustic parameters from samples of sustained vowels and 2 from connected speech were measured. The results show that jitter, shimmer and cepstral peak prominence (CPP) are correlated with the perception of hoarseness in sustained vowels. CPP is strongly correlated with the perception of hoarseness in connected speech. Some evidence is seen that perception of hoarseness in connected speech is more valid than the perception of hoarseness in sustained vowels. It is concluded that CPP for connected speech is a more valid objective measure of hoarseness than jitter, shimmer or CPP for sustained vowels and that perception of hoarseness may be most accurate in connected speech, rather than isolated vowels.
