Adaptive algorithms are widely used for acoustic echo cancellation (AEC). In this paper, an efficient switching tactic with advantageous features of NLMS and APA is proposed for AEC application. Switching points are decided by employing a smart voice activity detection scheme based on speech utterance. The speech signal is distinguished as voiced, unvoiced and silent periods then switch mechanism will automatically assign algorithm, either NLMS or APA, to the corresponding period. The prime motive of this proposed switch algorithm is to reduce the computational complexity and get better output over the NLMS but close to APA. Simulation results show the performance of proposed scheme is significantly improved.
