| 摘 要： | 喉部送话器具有很强的抗环境噪声干扰的能力,但使用时内部会产生一定的噪声。本文利用同步录音的麦克风语音信号和喉部送话器语音信号的相关性,用自适应线性滤波法提取出了喉部送话器的噪声信号,对其特性进行了分析,并提出了解决方案。

| Abstract: | The laryngophone , in spite of its strong ability of anti-environment, will produce a certain noise itself while being used. In this paper, by making use of the relevance of the microphone speech signal with the laryngphone speech signal recorded synchronously, the noise signal of the laryngophone is abstracted by the auto-adaptive linear filter, and based on this, its characteristics are analyzed and the solution is put forward. |

| Keywords: | non-air spread speech noise characteristics subtraction in frequency domain speech enhancement |
