ABSTRACT:
A method for determining a talk/listen state using voice detection includes receiving an audio sample and detecting whether the audio sample includes voiced sound. The audio sample represents sound measured during a sample time interval. The method further includes deriving an audio level from the audio sample and comparing the audio level to a threshold level. The audio level represents an average power level of the audio sample. The method further includes determining the talk/listen state depending on a relation of the audio level to the threshold level and depending on whether the audio sample includes voiced sound.
