Abstract :
The paper presents issues of time-delay estimation with application to the direction of sound arrival. The example shows that in the case of voice sources the percentage of correct GCCPHAT estimates is not acceptable. The proposed averaging filter significantly reduces the errors. The dependency of the timedelay estimation accuracy is experimentally evaluated.
