背景资料：语音质量的评估可以通过标准临床实践进行感知评估，还包括数字语音记录的声学评估，以验证和进一步解释感知判断。本研究的目的是使用一种新的临床声学工具VOXplot软件分析持续元音[a：]时，确定感知嘶哑和呼吸的最强声音质量参数。方法：对218例嗓音障碍者和正常者的嗓音样本进行知觉和声学分析。总的来说，13个单一的声学参数，包括确定有效性方面的感知声音嘶哑和呼吸。结果：四个单一的声学措施可以明确地与感知的声音嘶哑或呼吸。对于声音嘶哑，谐波噪声比（HNR）和音高扰动商与平滑因子为5个周期（PPQ5），以及，对于呼吸，平滑倒谱峰值突出度（CPPS）和声门噪声激励比（GNE）被证明是高度有效的，与其他感知语音质量方面的每一个显着差异。结论：两个声学措施，HNR和PPQ5，都与声音嘶哑的看法，并能够区分声音嘶哑的呼吸有很好的信心。另外两个声学测量，CPPS和GNE，都与呼吸的感知密切相关，并且能够以良好的信心区分呼吸和声音嘶哑。
Background: The assessment of voice quality can be evaluated perceptually with standard clinical practice, also including acoustic evaluation of digital voice recordings to validate and further interpret perceptual judgments. The goal of the present study was to determine the strongest acoustic voice quality parameters for perceived hoarseness and breathiness when analyzing the sustained vowel [a:] using a new clinical acoustic tool, the VOXplot software. Methods: A total of 218 voice samples of individuals with and without voice disorders were applied to perceptual and acoustic analyses. Overall, 13 single acoustic parameters were included to determine validity aspects in relation to perceptions of hoarseness and breathiness. Results: Four single acoustic measures could be clearly associated with perceptions of hoarseness or breathiness. For hoarseness, the harmonics-to-noise ratio (HNR) and pitch perturbation quotient with a smoothing factor of five periods (PPQ5), and, for breathiness, the smoothed cepstral peak prominence (CPPS) and the glottal-to-noise excitation ratio (GNE) were shown to be highly valid, with a significant difference being demonstrated for each of the other perceptual voice quality aspects. Conclusions: Two acoustic measures, the HNR and the PPQ5, were both strongly associated with perceptions of hoarseness and were able to discriminate hoarseness from breathiness with good confidence. Two other acoustic measures, the CPPS and the GNE, were both strongly associated with perceptions of breathiness and were able to discriminate breathiness from hoarseness with good confidence.
