| Abstract: | In order to detect more robustly and precisely the endpoints of speech under noisy environments, a novel endpoints detection method is proposed based on multi-band spectrum subtraction theory. Simulation results show that, as compared with the traditional algorithm based on the short-time energy or zero crossing rate, the proposed method can effectively detect the endpoints of speech at low SNR. |
