A wireless transceiver is provided for transmitting and receiving audio data, comprising: a microphone configured to generate a digital audio signal that includes the audio data, based on a received sound sampled into digital format; a voice detection circuit configured to detect the presence of voice activity in the audio data, and to generate a voice detection signal indicating whether the voice activity is present in the audio data; a transceiver circuit configured to transmit the audio data over a wireless medium; and a control circuit configured to control transmission of the audio data over the wireless medium by the transceiver circuit, based on the voice detection signal. This allows saving of transmission power since no transmission is done during the silence periods. The digital audio signal is at least one of a pulse code modulated signal without compression, and a Bluetooth signal.
