A new fast algorithm for estimating and tracking the location of a desired talker using a microphone array

摘要

Estimating and tracking the location of a desired talker are two basic tasks of microphone arrays.In this paper,we propose a new algorithm capable of rapidly estimating and tracking the desired talker's location in the far or near field with microphone arrays.The proposed algorithm is applicable to low signal-to-noise ratio (SNR) and short observation time scenarios where both rever-beration,and strong interference are present.We also conduct experiments based on both computer simulated data and real data captured with an experimental microphone array to demonstrate the effectiveness of our algorithm.
