Abstract
A transmission device such as a cell phone or other mobile communication device includes a physical phenomenon detection device to perform a “push to talk” function by detecting the occurrence of a particular physical phenomenon and using such detection to start and stop recording an utterance for subsequent analysis by a speech recognition engine. A method of controlling operation of a speech recognition engine in response to detection of a physical phenomenon includes detecting or sensing, via a physical phenomenon detection unit, a predetermined physical phenomenon representative of an intent to invoke operation of a speech recognition engine. In response to the detection or sensing of the predetermined physical phenomenon, a signal is transmitted to a control unit in a communication device. In response to the receipt of the transmitted signal, the utterance received from a user via the communication device is recorded, and the recorded utterance is provided to a speech recognition engine for operation thereon. The user may thus effectuate operation of the speech recognition engine upon the utterance by causing the physical phenomenon to occur.
