Abstract: A voice-activated encoding method includes determining a voice power parameter based on a frequency domain representation of a voice signal from a voice microphone. The method includes determining an ambient power parameter based on a frequency domain representation of at least one ambient signal from at least one ambient microphone spaced from the voice microphone. The method also includes enabling encoding of an audio signal based on the voice signal in response to comparing the power parameters and a threshold value. A headset including a controller may use the method to determine whether to enable or disable encoding, transmission, or both of an audio signal to another device.
