Abstract

Objectives: The current study aimed to classify voice signals using narrowband spectrograms and investigate acoustic measures in samples classified as type 1 and rated normal based on auditory-perceptual evaluation.

Methods: Voice samples of sustained phonation of /a/ of 234 males and 223 females aged between 4 and 16; 11 years were recorded and classified into 5 age groups. Narrowband spectrograms were generated and signal typing was done by two raters. Acoustic parameters for type-I signals were derived using PRAAT software (version 6.3.01). Inter-rater reliability was measured for both signal typing and auditory-perceptual evaluation.

Results: Based on agreement by two raters, around 79% of samples were classified as type 1, 8.5% as type II, and 7.8% as type-III signals. Inter-rater reliability for signal typing and GRBAS (Grade,Roughness, Breathiness, Asthenia, Strained) rating were found to be good (Intraclass Correlation Coefficient-0.90 and 0.81). Overall comparison using analysis of variance revealed statistically significant difference F0-related measures and NHR values (P < 0.05). Within males and females, F0 measures were statistically significant (P < 0.05). Noise-related measures were significant in males (P < 0.05). Independent t test revealed sex differences for F0 measures, jitter %, and NHR values in children above 13 years of age (P < 0.05).

Conclusions: Normative data obtained in this study can be used as a reference to compare with children with pediatric dysphonia.

印度学龄儿童嗓音的信号类型和声学分析

研究目的本研究旨在使用窄带频谱图对嗓音信号进行分类，并调查根据听觉感知评估被划分为 1 型和正常的样本的声学指标：记录了 234 名男性和 223 名女性持续发音 /a/ 的语音样本，年龄在 4 至 16；11 岁之间，并将其分为 5 个年龄组。由两名评分员生成窄带频谱图并进行信号分型。使用 PRAAT 软件（6.3.01 版）得出 I 型信号的声学参数。对信号分型和听觉感知评估的评分者之间的可靠性进行了测量：结果：根据两名评分者的一致意见，约 79% 的样本被归类为 1 型信号，8.5% 的样本被归类为 II 型信号，7.8% 的样本被归类为 III 型信号。信号分型和 GRBAS（等级、粗糙度、呼吸感、气喘、紧张）评级的评分者间可靠性良好（类内相关系数-0.90 和 0.81）。采用方差分析进行的总体比较显示，F0 相关测量值与 NHR 值之间存在显著的统计学差异（P 结论：F0 相关测量值与 NHR 值之间存在显著的统计学差异：本研究获得的标准数据可作为与小儿发音障碍儿童进行比较的参考。
