| Abstract(in English) | Desired/undesired speech discrimination is as important as speech/non-speech discrimination to achieve useful applications such as speech interfaces and teleconferencing systems. Conventional methods of voice activity detection utilize the directional information of sound sources to distinguish desired from undesired speech and have to utilize multiple microphones. Here, we assumed that the desired talkers would be close to the microphone, and we proposed a new method to discriminate close-talking speech from distant-talking speech with a single microphone based on the kurtosis of the linear prediction residual signals. The experimental results revealed that the proposed method could distinguish close-talking speech from distant-talking speech within a 10% equal error rate in ordinary reverberant environments with real-time processing. |
