A Noise Robust Endpoint Detection Algorithm for Whispered Speech Based on Empirical Mode Decomposition and Entropy

This paper proposes a novel endpoint detection algorithm to improve the speech detection performance in noisy environments. In the proposed algorithm, Empirical Mode Decomposition is introduced to improve the performance of voice activity detector based on spectral entropy. We have evaluated system performance under noisy environments using a whispered database and NOISEX-92 Database. Experimental results indicate that our approach performs well in the degraded environment.
