本研究的目的是调查受过古典训练的歌手在发声颤音过程中如何利用听觉反馈来控制基频 (fo)。解决了两个主要问题：（a）歌手在产生指示反馈控制的颤音期间，是否对其听觉反馈的 fo 的突然扰动产生反射性 fo 反应？ (b) 在产生表示反馈和前馈控制的颤音期间，歌手是否对其听觉反馈的 fo 的重复扰动产生适应性 fo 响应？此外，还解决了一个方法论问题，以确定在重复 fo 扰动范式期间，有或没有 fo 听觉提示时是否可以更精确地评估适应性 fo 反应。 10 名受过古典音乐训练的歌手发出带有颤音的持续元音，同时他们的听觉反馈的 fo 和和声突然受到 100 音分的干扰，以评估反射控制，或反复受到 100 音分的干扰，以评估适应性控制。一半参与者在有 fo 听觉提示的情况下完成了重复扰动实验，另一半在没有 fo 听觉提示的情况下完成了实验。声学分析测量了平均 fo 响应听觉反馈扰动的变化。平均而言，参与者会对听觉反馈的突然和反复扰动产生补偿反应。对重复扰动的响应幅度大于对突然扰动的响应。在有提示、重复的扰动实验中，响应也比在无提示、重复的扰动实验中更大。这些发现表明，受过古典训练的歌手在颤音制作过程中使用前馈和反馈机制来控制他们的平均 fo。与之前对歌手产生稳定声音的研究相比，本研究中的反射性响应更大，这可能表明反馈控制系统在颤音产生过程中参与更多。
The purpose of this study was to investigate how classically-trained singers use their auditory feedback to control fundamental frequency (fo) during production of vocal vibrato. Two main questions were addressed: (a) Do singers produce reflexive fo responses to sudden perturbation of the fo of their auditory feedback during production of vibrato indicative of feedback control? (b) Do singers produce adaptive fo responses to repeated perturbation of the fo of their auditory feedback during production of vibrato indicative of feedback and feedforward control? In addition, one methodological question was addressed to determine if adaptive fo responses were more precisely assessed with or without an auditory cue for fo during the repeated fo perturbation paradigm. Ten classically-trained singers produced sustained vowels with vibrato while the fo and harmonics of their auditory feedback were suddenly perturbed by 100 cents to assess reflexive control or repeatedly perturbed by 100 cents to assess adaptive control. Half of the participants completed the repeated perturbation experiment with an auditory cue for fo, and the other half completed the experiment without an auditory cue for fo. Acoustical analyses measured changes in mean fo in response to the auditory feedback perturbations. On average, participants produced compensatory responses to both sudden and repeated perturbation of the fo of their auditory feedback. The magnitude of the responses to repeated perturbations were larger than the responses to sudden perturbations. Responses were also larger in the cued, repeated fo perturbation experiment than in the uncued, repeated fo perturbation experiment. These findings indicate that classically-trained singers use both feedforward and feedback mechanisms to control their average fo during production of vibrato. When compared to prior studies of singers producing a steady voice, the reflexive fo responses were larger in the current study, which may indicate that the feedback control system is engaged more during production of vibrato.
