| 摘 要： | 本文旨在分析一般的家庭住室环境中,各种噪声对语声控制系统正常工作的干扰问题。指出,电视机等电器发出的语声,是最为严重的干扰噪声。为此,本文引入ANC方法这一有效的语音增强技术,提出了一种用于家用电器声控制技术的干扰噪声消除方案。本文将声波的波动概念引入室内几何声学,提出一种能够简捷计算矩形室内声场中声通道传递函数的新方法,以及用此方法仿真了传递函数随一些客观因素而变化的情况。

| Abstract: | This paper studies the possihility and necessity of making the. voice control technique for household appliances go into use as soon as possinle. Therefore, the speech signal enhancement technique, automatic control engineering and room acoustics are used to solve the very problem the noise, interference problem in the voice control technique for household appliances In this paper, the adaptive noise cancelling (ANC) system is designed. In the meantime a new method about room acoustics is studied and used to analyze the room-acoustic field. As a result, the frequency response function of wave transmitting path has been calculated by a computer's simulation program, which is of utmost importance for the ANC to be designed. |
