Abstract:
A wireless communication device (300) including a voice activity detector (330), and a codec (320) outputting an audio data packet based on a transducer (310) output after the onset of audio input thereto. A control module prompts initiating setup of a temporary block flow when the voice activity detector detects audio input to the transducer. The control module also prompts initiating setup of the temporary block flow before the audio data packet is output to a buffer.
