Abstract: Improved audio processing management in a portable converged communication device is provided. A default mode of audio processing is provided where audio input to a microphone is routed and processed simultaneously to a plurality of different processors in parallel. The default mode is suspended in response to a keyword input to a microphone. The keyword is recognized by a speech recognition engine (ASR). The keyword enables audio processing through one of the plurality of processors while selectively suspending other audio processing through the other processors.
