摘要

本文介绍了一种使用麦克风阵列的鲁棒语音编码器。阵列处理器的功能是作为噪声消除器和语音活动检测器，因此即使在极端噪声条件下(信噪比<0 dB)，编码器也可以提高语音质量并降低比特率。初步结果表明，该方案在几种噪声和混响室内环境下是有效的。

Robust speech coding using microphone arrays

The paper describes a robust speech coder that uses a microphone array. The array processor functions as a noise canceller and a voice activity detector, thus giving the coder improved speech quality and lowered bit rates even in extremely noisy conditions (SNR<0 dB). Preliminary results have shown the effectiveness of the scheme under several noisy and reverberant room environments.
