A method and apparatus for detecting use of an utterance. A voice session including voice signals generated during a conversation between a first participant and a second participant is monitored by a speech analytics processor. The speech analytics processor detects the use of an utterance. A speech recognition processor channel selected from a pool of speech recognition processor channels and is coupled to the voice session. The speech recognition processor provided speech recognition services to a voice-enabled application. The speech recognition processor channel is then decoupled from the voice session. The speech analytics processor continues to monitor the conversation for subsequent use of the utterance.
