最近关于发声的神经生理学研究开始阐明发声过程中听觉反馈处理的神经机制。在这里，我们回顾了研究成果如何影响我们的语音运动控制的状态反馈控制(SFC)模型。我们将讨论皮质计算的证据，该计算将传入的反馈与来自运动传出复制的预测进行比较。我们还将回顾来自听觉反馈扰动研究的观察结果，这些研究证明了状态估计校正过程的明确证据，该过程驱动代偿性运动行为反应。尽管SFC模型中的皮质计算得到了令人信服的支持，但仍有几个悬而未决的问题等待未来的神经研究来解决。
Recent neurophysiological studies of speaking are beginning to elucidate the neural mechanisms underlying auditory feedback processing during vocalizations. Here we review how research findings impact our state feedback control (SFC) model of speech motor control. We will discuss the evidence for cortical computations that compare incoming feedback with predictions derived from motor efference copy. We will also review observations from auditory feedback perturbation studies that demonstrate clear evidence for a state estimate correction process, which drives compensatory motor behavioral responses. While there is compelling support for cortical computations in the SFC model, there are still several outstanding questions that await resolution by future neural investigations.
