概括
语音前听觉调制 (PSAM) 在元音开始时影响语音声学,这表明它有助于运动指令的准备,而不是对语音纠正的反监测.
科学领域:
- 神经科学是一个神经科学.
- 语音科学 语言科学
- 审计处理 审计处理
背景情况:
- 在语音开始之前,听觉处理是调制的.
- 这种语音前听觉调制 (PSAM) 的功能尚不清楚.
- 目前尚不清楚PSAM是否有助于纠正语音错误.
研究的目的:
- 调查PSAM是否为优化反监测准备了听觉皮层.
- 确定PSAM是否与语音制作期间的关节调整相关.
- 探索PSAM在语音前与反控制中的作用.
主要方法:
- 结合了脑电图 (EEG) 的PSAM数据与声学语音测量.
- 量化在线关节性调整,使用试验间的形式变化 (集中).
- 分析了在元音开始和中点时的PSAM和形式变化.
主要成果:
- 试验间的形式变化从元音开始到中点减少.
- PSAM与形式变化的变化没有相关性 (单音内调整).
- 较高的PSAM与较低的形式变化在母音开始时相关.
结论:
- 显然,PSAM在发音的早期影响了语音声学 (元音开始).
- 研究结果表明,PSAM参与了机动指挥准备 (Feedforward控制).
- 在线语音输出监控 (反控制) 中,PSAM可能不是主要的功能.

Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

When we hear a sound, our nervous system is detecting sound waves—pressure waves of mechanical energy traveling through a medium. The frequency of the wave is perceived as pitch, while the amplitude is perceived as loudness.
