Abstract

Objectives

Although vowels are of interest for acoustic analysis in clinics, there is no consensus regarding the effect of vowel selection on acoustic perturbation parameters. This study aimed to reveal the effects of Mandarin vowels on acoustic measurements.

Study Design

A prospective observational study.

Methods

This prospective observational study enrolled normal phonation Mandarin speakers at the Otolaryngology Department of the Eye & ENT Hospital affiliated with Fudan University from December 2020 to August 2021. This study recruited 107 normal-voiced Mandarin speakers (59 women and 49 men) with a median age of 26 (22, 33) years old. The objective measures included traditional acoustic parameters (fundamental frequency, harmonic-to-noise ratio, percent jitter, and percent shimmer) and cepstral analysis (smoothed cepstral peak prominence) of six Mandarin vowels (ɑ /a/, o /o/, e /ɤ/, i /i/, u /u/, ü /y/).

Results

The acoustic analysis revealed no significant differences in the fundamental frequency among vowels. The low vowel /a/ had the highest values for percent jitter and percent shimmer and the lowest harmonic-to-noise ratio value. The back vowel /u/ had the lowest cepstral measures (P < 0.05).

Conclusions

The acoustic analysis significantly varied across the different Mandarin vowels, and these differences must be considered for the effective clinical application of objective evaluations.

普通话元音对声学分析的影响：前瞻性观察研究

目的：虽然声母是临床声学分析的兴趣所在，但关于声母选择对声学扰动参数的影响还没有达成共识。本研究旨在揭示普通话元音对声学测量的影响：研究设计：前瞻性观察研究：本前瞻性观察研究于 2020 年 12 月至 2021 年 8 月在复旦大学附属眼耳鼻喉科医院耳鼻喉科招募了正常发音的普通话使用者。该研究共招募了107名普通话发音正常者（59名女性和49名男性），中位年龄为26（22，33）岁。客观测量包括六个普通话元音（ɑ /a/、o /o/、e /ɤ/、i /i/、u /u/、ü /y/）的传统声学参数（基频、谐波噪声比、抖动百分比和闪烁百分比）和倒频谱分析（平滑倒频谱峰突出）：声学分析表明，不同元音的基频没有明显差异。低元音 /a/ 的抖动百分比和闪烁百分比值最高，谐噪比值最低。后元音 /u/ 的共谱测量值最低（P < 0.05）：不同普通话元音的声学分析结果差异很大，在临床上有效应用客观评估时必须考虑这些差异。
