Abstract
According to one embodiment of the invention, an apparatus is provided which includes an encoder to encode input speech signals. The speech signals contain frames of talk spurts and silence gaps. The apparatus further includes a voice activity detector coupled to the encoder, the voice activity detector to detect whether a current frame of the input speech signals is the first active frame of a talk spurt. In response to the voice activity detector detecting that the current frame is the first active frame of a talk spurt, the encoder is reset and the encoder states are initialized.
