| Abstract(in English) | The VAD method proposed in this paper integrates multiple speech features and a signal decision scheme, namely the speech periodic to aperiodic component ratio and a switching Kalman filter. The integration is carried out by using the weighted sum of likelihoods outputted from each VAD (stream). The stream weight is decided adaptively each short time frame. The evaluation is carried out by using a VAD evaluation framework, CENSREC-1-C. The evaluation results revealed that the proposed method significantly outperforms the baseline results of CENSREC-1-C as regards VAD accuracy in real environments. In addition, we examine the method of likelihoods weighting through the experiments. |
