Abstract
The location and tracking of the sound source is an important aspect in the speech communication and recognition. The method of source location and tracking based on the time delay is presented in this paper. According to the characteristic of noise, the FLOC (fractional lower order covariance) and CSP (cross-power spectrum phase) are selected to estimate the time delay, which can quickly determine and tracking the sound source location. The better result is acquired with the experiments.
