Study on localization for speech based on microphone array

基于麦克风阵列的声源定位是有效声源提取的前提和基础,其技术在多媒体通信中得到了广泛的应用.讨论了基于麦克风均匀线阵和均匀圆阵的声源定位方法,并进行了仿真,其结果表明这两种模型均能有效地提取出声源的位置.并给出了算法的硬件实现的原理框图.

Speech sources localization based on microphone array is the basic for extraction of the interesting speech source, which is applied broadly in multimedia communication. In this paper, the methods for speech sources localization based on uniform linear array and on uniform circular array are discussed, and their digital simulation have been taken. The simulation results show that they can effectively extract the localization of speech source. The hardware scheme to implement these algorithms have been given in this paper.
