Evidence regarding the application of telepractice voice training in theater actors is inconclusive. Our study aimed to investigate changes in acoustic parameters, auditory-perceptual characteristics, and self-reported voice symptoms of theater actors with voice complaints undergoing telepractice voice training.
Nine theater actors with voice complaints participated in this single-group intervention. In this pre-post study, we observed changes in the participants' voice quality. The participants received twelve online voice training sessions over six weeks. An auditory-perceptual evaluation was performed using the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V) profile to analyze the voice, while acoustic parameters were extracted from the recordings using Praat software. In addition, the Vocal Tract Discomfort Scale (VTDS) was administered as a self-report questionnaire. Outcome variables were measured pre-, post, and four weeks after the end of the training. The variables were then subjected to variance analysis with repeated measurements.
Voice training resulted in significant changes in acoustic parameters, such as jitter and HNR. Additionally, over time, significant improvements were observed in auditory-perceptual characteristics, including overall severity, roughness, breathiness, and strain.
Telepractice voice training has the potential to enhance the voice quality of actors who experience voice complaints. However, more specific measures are necessary to fully understand the effectiveness of telepractice voice interventions compared with traditional face-to-face sessions.
关于远程语音训练在戏剧演员中的应用证据尚无定论。我们的研究旨在调查接受远程语音训练的有嗓音问题的戏剧演员的声学参数、听觉感知特征和自我报告的嗓音症状的变化。
九名有嗓音问题的戏剧演员参与了这一单组干预研究。在这项前后对照研究中,我们观察了参与者嗓音质量的变化。参与者在六周内接受了十二次在线语音训练课程。使用嗓音的共识听觉感知评估(CAPE-V)简表进行听觉感知评估以分析嗓音,同时使用Praat软件从录音中提取声学参数。此外,使用声道不适量表(VTDS)作为自我报告问卷。在训练前、训练后以及训练结束后四周测量结果变量。然后对这些变量进行重复测量的方差分析。
语音训练导致声学参数发生显著变化,如抖动和谐噪比。此外,随着时间的推移,在听觉感知特征方面观察到显著改善,包括总体严重程度、粗糙度、呼吸声和紧张度。
远程语音训练有可能提高有嗓音问题的演员的嗓音质量。然而,与传统面对面课程相比,需要更具体的措施来充分了解远程语音干预的有效性。
