中文摘要
目的： 本研究探讨在嗓音声学录音过程中，可见麦克风的存在是否会影响嗓音障碍患者和对照者的声学测量指标及自我报告的嗓音状态。
方法： 共纳入17名参与者（7名嗓音障碍患者；10名对照者）。嗓音录音包括连续言语和持续元音。这些任务分别在可见麦克风条件和非可见麦克风条件下进行，顺序随机，并在45分钟嗓音使用前后各进行一次。声学嗓音结局包括声压级、平滑倒谱峰突出度和时间剂量等测量指标。自我报告的嗓音状态评分包括嗓音不适、嗓音努力和嗓音一致性。
结果： 麦克风可见性与较低的声压级值和较高的时间剂量值相关。麦克风可见性对自我报告的嗓音不适、嗓音努力或嗓音一致性没有显著影响。探索性组间比较表明，患者报告的嗓音不适和努力程度高于对照者，嗓音一致性低于对照者。
结论： 在本样本中，麦克风可见性与某些声学结局的变化相关，但与自我报告嗓音状态的显著变化无关。这些发现表明，即使在说话者未报告相应嗓音状态变化的情况下，麦克风可见性也可能影响临床嗓音评估中说话者的嗓音产生方式。结果强调了在声学嗓音评估中考虑录音环境的重要性。
英文摘要
PURPOSE: This study examines whether the presence of a visible microphone during acoustic recordings of voice affects acoustic measures and self-reported vocal status in patients with voice disorders and controls.
METHOD: Seventeen participants (7 with voice disorders; 10 controls) were enrolled. Voice recordings involved connected speech and a sustained vowel. These tasks occurred during a visible microphone condition and a non-visible microphone condition, presented in random order, before and after 45 minutes of voice use. Acoustic voice outcomes included measures of sound pressure level, cepstral peak prominence smoothed, and time dose. Self-reported vocal status ratings included vocal discomfort, vocal effort, and vocal congruence.
RESULTS: Microphone visibility was associated with lower sound pressure level values and higher time dose values. There was no significant effect of microphone visibility on self-reported vocal discomfort, vocal effort, or vocal congruence. Exploratory group comparisons indicated that patients reported greater vocal discomfort and effort and lower vocal congruence than controls.
CONCLUSION: In this sample, microphone visibility was associated with changes in certain acoustic outcomes but not with significant changes in self-reported vocal status. These findings suggest that microphone visibility may influence how speakers produce voice during clinical-voice evaluations, even when speakers do not report a corresponding change in vocal status. The results reinforce the importance of considering the recording context during acoustic voice assessments.
