Abstract :
Estimation of speakers' directions is one of the interesting topics. In this paper, we introduce the TFCS algorithm for direction-of-arrival estimation of multiple speakers. In this algorithm, no limitations are imposed on the environment and speech signals. Simulation results show that the proposed algorithm outperforms the recently addressed onset and spectral-based methods.
