Kinesthetic auditory feedback during phonation

项目摘要

The precision of the human speech signal is controlled by parallel working feedback processes while speaking. The feedback mechanisms are developed during language acquisition and can be divided into kinesthetic and auditory control. The feedback mechanisms can be affected by voice and speech disorders in different ways. This project investigates the feedback mechanisms of phonation and articulation of healthy test persons and compares their performance with patients suffering from voice disorders (hyper-, hypotension dysphonia (MTD)) and speech disorder (Apraxia of Speech (AOS)). The synchronous data acquisition (visual and EEG) enables for the first time the analysis of the connection between kinesthetic and auditory feedback processes. Current methods of electrophysiology and quantitative endoscopy are used simultaneously.The hypotheses are: (1) The kinesthetic feedback process is faster than the auditory control (fine-tuning). (2) Voice and speech disordered patients display an impairment of the kinesthetic feedback process.The goal of the study is a first understanding of the cooperating auditory and kinesthetic feedback control. Both processes will be compared with regard to their function and speed of processing. Therefore, the pitch shift reflex (adaptation or compensation of the tone) will be evoked in 60 adults, consisting of 20 adults for the control group, 20 with a voice disorder and 20 with a speech disorder. The Mismatch-Negativity (MMN) will be conducted via EEG and the induced changes of vocal fold vibrations will be recorded simultaneously via High-Speed Video Endoscopy.

人类语音信号的精度是由说话时并行工作的反馈过程控制的。反馈机制是在语言习得过程中形成的，可分为动觉控制和听觉控制。反馈机制可能会以不同的方式受到声音和言语障碍的影响。该项目研究了健康测试者的发声和发音的反馈机制，并将他们的表现与患有声音障碍（高、低血压发声困难（MTD））和言语障碍（言语失用症（AOS））的患者进行比较。同步数据采集（视觉和脑电图）首次能够分析动觉和听觉反馈过程之间的联系。当前的电生理学方法和定量内窥镜检查同时使用。假设是：（1）动觉反馈过程比听觉控制（微调）更快。 (2) 声音和言语障碍患者表现出动觉反馈过程的损伤。该研究的目标是首先了解协作的听觉和动觉反馈控制。将比较这两个过程的功能和处理速度。因此，将在 60 名成年人中诱发音高转换反射（音调的适应或补偿），其中 20 名成年人为对照组，20 名患有语音障碍，20 名患有言语障碍。失配负性（MMN）将通过脑电图进行，声带振动引起的变化将通过高速视频内窥镜同时记录。
