Abstract(in English) | To realize a robust voice activity detection (VAD) method in real acoustic environments, we have proposed a VAD method using environment sound models and HMM composition. The proposed method predicts the environment sound that overlaps with the speech, then composes the speech model and the model of the predicted environment sound, and detects the mixture sound period by using the composed models. In this paper, the proposed method is applied to the case of sentence utterances. To evaluate the performance of the proposed method, experiments were conducted. These results showed that the VAD accuracy of the proposed method is improved by a maximum of 4.7% compared to that of the conventional methods. |
