Performers (10 actors/10 singers) rated via a self-report questionnaire the severity of their voice-related changes when vocally fatigued. Similar frequency patterns and perceptual features of vocal fatigue were found across subjects. Actors rated "power" aspects (e.g., voice projection) and singers rated vocal dynamic aspects (e.g., pitch range) of their voices as most affected when vocally fatigued. Vocal fatigue was evidenced by changes in kinesthetic/proprioceptive sensations and vocal dynamics. The causes and context of vocal fatigue were vocal misuse, being "run down," high performance demands, and using high pitch/volume levels. Further research is needed to delineate the perceptual features of "normal" levels of vocal fatigue and its possible causes.
表演者（10名演员/10名歌手）通过一份自我报告问卷对其嗓音疲劳时与嗓音相关变化的严重程度进行了评分。在所有受试者中发现了相似的嗓音疲劳频率模式和感知特征。演员们认为嗓音疲劳时，他们声音的“力量”方面（如声音投射）受影响最大，而歌手们则认为是声音的动态方面（如音域）受影响最大。动觉/本体感觉和声音动态的变化证明了嗓音疲劳的存在。嗓音疲劳的原因和背景包括嗓音使用不当、“疲惫不堪”、高表演要求以及使用高音调/高音量。需要进一步研究来描绘“正常”水平嗓音疲劳的感知特征及其可能的原因。
