Acoustic and endoscopic voice assessments are routinely performed to determine the vocal fold vibratory function as part of the voice assessment protocol in clinics. More often than not these data are separately recorded, resulting in information being obtained from two different phonation segments and an increase of time for the voice evaluation process. This study explores the use of acoustic data, simultaneously recorded during high-speed endoscopy (HSE), for the evaluation of vocal fold function.
HSE and acoustic data were recorded from the subjects simultaneously during sustained phonation. The data included voices of 73 healthy subjects, 148 paresis, 210 functional dysphonias, and 119 benign lesions of vocal folds. For this study, only acoustic data were analyzed using Dr. Speech software (Tiger electronics Inc., MA). Twelve parameters were computed; 82% of the acoustic voice recordings could be analyzed. Statistical analysis was performed with SPSS 17.0.
Acoustic data was easily recorded simultaneously allowing analyses of the same phonation segment to determine vocal fold function and therefore eliminating the need for another voice recording. The acoustic voice parameters differed between genders in the healthy voice group. Most of the parameters showed significant differences between healthy and pathological groups.
Simultaneously recorded endoscopic and acoustic data is valuable. Differentiation between healthy and pathological groups was possible using acoustic data only. We suggest that the synchronously recorded acoustic signal is of sufficient quality for objective analysis yielding reduced examination time.
作为临床嗓音评估协议的一部分，通常进行声学和内窥镜嗓音评估以确定声带的振动功能。这些数据通常是分开记录的，这导致信息是从两个不同的发音段获取的，并且嗓音评估过程的时间增加。本研究探讨了在高速内窥镜（HSE）期间同时记录的声学数据在评估声带功能中的应用。
在持续发声期间，从受试者同时记录 HSE 和声学数据。数据包括 73 名健康受试者、148 名声带麻痹、210 名功能性嗓音障碍和 119 名声带良性病变的声音。在这项研究中，仅使用 Dr. Speech 软件（Tiger electronics Inc.，MA）分析声学数据。计算了 12 个参数；可分析 82%的声学语音记录。使用 SPSS 17.0 进行统计分析。
声学数据很容易同时记录，允许对同一发音段进行分析以确定声带功能，从而无需再进行另一次语音录音。健康语音组中，声学语音参数因性别而异。大多数参数在健康组和病理组之间存在显著差异。
同时记录的内窥镜和声学数据是有价值的。仅使用声学数据即可区分健康组和病理组。我们建议，同步记录的声学信号质量足以进行客观分析，从而缩短检查时间。
