Abstract
To carry out a real-time sound source localization system with a small amount of microphones, a specific implementation method is presented in this paper. This method comprises two steps: time delay estimation and position calculation. Firstly, the modified cross power spectrum phase algorithm (M-CPSP) is applied to time delay estimation, which has higher precision of time delay estimation in real-time environments. Moreover, the cross array model with four microphones is applied to this system and sound source position is calculated by the geometrical relationship between the spatial coordinates of four microphones and time delay. Experimental results show that the M-CPSP algorithm has a high accuracy of time delay estimation in strong noisy and reverberant environments and the error of distance positioning is less than ±25cm, the error of angle positioning is less than ±5o, which meets the needs of practical application.
