| Abstract(in English) | This paper proposes a new voice activity detection (VAD) method using non-speech models and HMM composition. The proposed method predicts a non-speech sound that overlaps with speech by a Viterbi algorithm with a speech model and non-speech models. Then, a Viterbi algorithm with composed models of the speech model and the predicted non-speech sound models is applied again. As a result, the overlap segments are detected. Furthermore, the non-speech sound that overlaps with speech and its SNR are identified. To evaluate the performance of the proposed method, preliminary experiments are conducted. These results showed that the VAD accuracy of the proposed method is improved by a maximum of 40% compared to that of the conventional method. |
