发明名称 Elimination of clipping associated with VAD-directed silence suppression
摘要 A method and apparatus for elimination of clipping associated with VAD-directed silence suppression includes receiving a voice signal in a buffer during the delay between the start of voice activity and the detection of the voice activity. Then, the voice signal is played from the buffer in condensed form, e.g., by dropping packets or slightly accelerating playback of the signal from the buffer. After voice activity is detected, the voice signal may continue to be buffered and condensed until the buffer is completely depleted. The voice signal may then be transmitted directly, without being buffered or condensed.
