| 摘 要： | 在免提通信系统中，麦克风阵列往往用于噪声和混响环境下的语音拾取。基于常用的麦克风阵列拓扑结构，推导了一个麦克风空间摆放对麦克风阵列性能影响的准则。仿真试验结果验证了理论分析的结论，即麦克风阵列的拓扑结构的确影响着语音增强系统的性能，优化的麦克风阵列摆放可以在一定程度上改善语音质量。

| Abstract: | In the hands-free communication systems where the noise and reverberation coexisted,microphone arrays were always used for the speech acquisition.The criterion was derived to evaluate the influence of spatial microphones placement on the systems.Simulation results verified that the microphone array configuration really affected the performance of speech enhancement system and the optimal microphones placement was able to improve the speech quality significantly. |
