在耳鼻喉科使用的不同程序中，语音声学分析已广泛用于正确诊断发声困难。在 COVID-19 大流行期间，人们普遍认为口罩会影响分析结果，因此声学参数的仪器测量受到限制。我们研究的目的是调查外科口罩对成人 F0、抖动、闪烁和谐波噪声比 (HNR) 的影响。该研究是在选定的 50 名健康受试者中进行的。语音样本直接在 Praat 中录制。所有受试者都接受训练，在佩戴外科口罩和不佩戴外科口罩的情况下，以对话语音强度、没有强度或频率变化、在最大发声时间 (MPT) 下发出持续的 /a/ 的声音样本。声学语音分析检测到佩戴外科口罩和未佩戴外科口罩的差异均不具有统计学意义。我们的研究表明，即使在 COVID-19 大流行期间，患者佩戴外科口罩也可以继续进行声学语音分析程序。
Among the different procedures used by the ENT, acoustic analysis of voice has become widely used for correct diagnosis of dysphonia. The instrumental measurements of acoustic parameters were limited during the COVID-19 pandemic by the common belief that a face mask affects the results of the analysis. The purpose of our study was to investigate the impact of surgical masks on F0, jitter, shimmer and harmonics-to-noise ratio (HNR) in adults. The study was carried out on a selected group of 50 healthy subjects. Voice samples were recorded directly in Praat. All subjects were trained to voice a vocal sample of a sustained /a/, at a conversational voice intensity, with no intensity or frequency variation, for the Maximum Phonation Time (MPT), wearing the surgical mask and then without wearing the surgical mask. None of the variations in acoustic voice analysis detected wearing a surgical mask and not wearing a surgical mask were statistically significant. Our study demonstrates that the acoustic voice analysis procedure can continue to be performed with the use of a surgical mask for the patient, even during the COVID-19 pandemic.
