作为临床声音评估方案的一部分，常规进行声学和内窥镜声音评估以确定声带振动功能。通常，这些数据是单独记录的，导致从两个不同的发声片段获得信息，并增加了语音评估过程的时间。本研究探讨了使用高速内窥镜检查 (HSE) 期间同时记录的声学数据来评估声带功能。在持续发声期间同时记录受试者的 HSE 和声学数据。数据包括 73 名健康受试者、148 名轻瘫受试者、210 名功能性发声困难受试者和 119 名声带良性病变受试者的声音。在本研究中，仅使用 Dr. Speech 软件（Tiger electronics Inc.，MA）分析声学数据。计算了十二个参数； 82% 的声学录音可以被分析。采用SPSS 17.0进行统计分析。声学数据可以轻松地同时记录，从而可以分析同一发声片段以确定声带功能，从而无需进行另一次录音。健康声音组中不同性别的声学声音参数存在差异。大多数参数在健康组和病理组之间表现出显着差异。同时记录的内窥镜和声学数据很有价值。仅使用声学数据就可以区分健康组和病理组。我们建议同步记录的声学信号具有足够的质量用于客观分析，从而减少检查时间。
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.
