Abstract
The speech source localization technology based on microphone array has been researched. The constructive method of the time delay estimation algorithm has been studied. On this basis, the hyperbola algorithm for the 2-d DOA estimation is proposed, realizing 2-d DOA estimation of the speech source localization using microphones MPA416 and data acquisition card PXI4472 combining virtual instrument of NI company. Experimental results show that this system has low complexity and high accuracy.关键词
