Sound source orientation technique is applied to robot platform

so that it has speech signal perception and orientation capability.Three stages of voice orientation technology is simulated.Firstly

voice endpoint is detected

and then time delay between two acoustic sensors is solved.Finally

combining the spatial geometry structure of acoustic sensor array

analyze orientation error.Simulation results show that the algorithm is simple and effective

it can effectively reduce amount of calculation

have certain anti-noise and reverberation ability and meet requirements of orientation precision and has certain guiding significance.
