Abstract :
We combine sound activity detection, sound enhancement, and direction of arrival (DOA) estimation system to an integrated system. We use sound activity detection for finding frames which are sound-dominated, then pass the signal to the subspace based sound enhancement for denoising. Finally, the denoised signal will be input to DOA detection system for sound tracking. The generalized cross-correlation and phase transformation (GCC-PHAT) based time difference of arrival (TDOA) estimation can detect the TDOA of the sound signal and then calculate the respondent DOA.
