Abstract

Introduction: In this study, the correlations between traditional acoustic measures (TAMs) and cepstral analysis (CA) were explored in Persian.

Methods: This investigation was a cross-sectional study including 179 dysphonic (n=141) and normophonic (n=38) speakers. The TAMs (jitter, shimmer, and noise-to-harmonic ratio) and CA (cepstral peak prominence, and cepstral peak prominence-smoothed) values were obtained during vowel prolongation, reading a standard sentence, and a non-standard running speech sample using Praat software. The difference of acoustic measures between normophonic and dysphonic speakers and intercorrelation among acoustic measures and correlation between the acoustic measures and perceived dysphonia levels was analyzed with independent t test, Mann-Whitney U test, Pearson, Spearman, and Kendall's Tau-b correlation tests using IBM SPSS Statistics.

Results: The findings showed that dysphonic speakers had higher TAM values and lower CA values than normophonic speakers. (P < 0.05). In dysphonic speakers, a large correlation was discovered among all acoustic measurements (r = 0.52 to 0.96; P < 0.05), while in various perceived dysphonic speakers, there was a correlation of varying strength (r = 0.25 to 0.97; P < 0.05). Ultimately, there was a significant small-to-large correlation between the acoustic measures and perceived dysphonia levels (r = 0.34-0.58; P < 0.05).

Discussion/conclusion: This research demonstrated that Persian speakers with dysphonia experienced a rise in TAM and a corresponding reduction in CA. In the future, multi-parametric indices can be developed using both TAM and CA to include various aspects of vocal production and yield a single, comprehensive value.

传统声学测量与嗓音倒频谱分析之间的关系
简介:本研究探讨了波斯语中传统声学测量(TAMs)与倒频谱分析(CA)之间的相关性:本研究探讨了波斯语中传统声学测量(TAMs)和倒频谱分析(CA)之间的相关性:本研究是一项横断面研究,包括 179 位发音障碍者(n=141)和正常发音者(n=38)。在元音延长、朗读标准句子和使用 Praat 软件进行非标准流畅语音采样时,获得了 TAMs(抖动、闪烁和噪声-谐波比)和 CA(epstral peak prominence 和 cepstral peak prominence-smoothed)值。使用 IBM SPSS 统计软件,通过独立 t 检验、Mann-Whitney U 检验、Pearson、Spearman 和 Kendall's Tau-b 相关性检验,分析了正常发音者和发音障碍者之间的声学测量差异、声学测量之间的相互关系以及声学测量与发音障碍感知水平之间的相关性:结果表明,与正常发音者相比,发音障碍者的 TAM 值较高,CA 值较低。(P < 0.05)。在发音困难的说话者中,所有声学测量值之间都存在很大的相关性(r = 0.52 至 0.96;P <;0.05),而在各种感知发音困难的说话者中,则存在不同强度的相关性(r = 0.25 至 0.97;P <;0.05)。最终,声学测量与感知发音障碍水平之间存在明显的由小到大的相关性(r = 0.34-0.58; P <0.05):这项研究表明,患有发音障碍的波斯语者的 TAM 会升高,CA 会相应降低。今后,可利用 TAM 和 CA 开发多参数指数,以包括发声的各个方面,并得出单一的综合数值。

期刊介绍: Published since 1947, ''Folia Phoniatrica et Logopaedica'' provides a forum for international research on the anatomy, physiology, and pathology of structures of the speech, language, and hearing mechanisms. Original papers published in this journal report new findings on basic function, assessment, management, and test development in communication sciences and disorders, as well as experiments designed to test specific theories of speech, language, and hearing function. Review papers of high quality are also welcomed.
