Using a physical phenomenon detector to control operation of a speech recognition engine
First Claim
1. A system comprising:
- a physical phenomenon detection unit configured to detect or sense heat radiated from a human face in proximity to the physical phenomenon detection unit; and
an electronic communication device comprising a control unit, the control unit being in communication with the physical phenomenon detection unit, the electronic communication device configured to;
record an utterance received from a user in response to detecting or sensing the heat radiated from the human face in proximity to the physical phenomenon detection unit; and
provide the recorded utterance to a speech recognition engine for operation thereon;
wherein the user may effectuate operation of the speech recognition engine on the utterance by bringing his or her human face in proximity to the physical phenomenon detection unit; and
wherein the physical phenomenon detection unit is further configured to detect or sense the heat radiated from the human face in proximity to the physical phenomenon detection unit without using key elements of the electronic communication device.

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.

4. A computer-implemented method of controlling a speech recognition engine, the computer-implemented method comprising:
-
as implemented at least in part by an electronic communication device comprising a control unit, the control unit being in communication with a physical phenomenon detection unit, prior to receiving, by the control unit, a signal from the physical phenomenon detection unit indicating that the physical phenomenon detection unit has detected or sensed a predetermined physical phenomenon representative of an intent to invoke operation of the speech recognition engine, receiving an input representative of an intent to place the electronic communication device in a standby state such that subsequent detecting or sensing of the predetermined physical phenomenon is enabled; receiving, by the control unit, the signal indicating that the physical phenomenon detection unit has detected or sensed the predetermined physical phenomenon representative of the intent to invoke operation of the speech recognition engine, the predetermined physical phenomenon being detected or sensed without using key elements of the electronic communication device; causing the electronic communication device to record an utterance received from a user in response to receiving the signal; and providing the recorded utterance to the speech recognition engine for operation thereon; wherein operation of the speech recognition engine on the utterance is effectuated upon occurrence of the predetermined physical phenomenon. - View Dependent Claims (5, 6, 7)

8. A non-transitory computer-readable medium having stored thereon a speech recognition control module configured to execute in a control unit of an electronic communication device, the control unit being in communication with a physical phenomenon detection unit comprising a first proximity sensor and a second proximity sensor, the speech recognition control module being further configured to:
-
detect or sense a first predetermined physical phenomenon via the first proximity sensor without using key elements of the electronic communication device, wherein the first predetermined physical phenomenon is representative of an intent to invoke operation of a speech recognition engine, and wherein operation of the speech recognition engine on the utterance is effectuated upon occurrence of the first predetermined physical phenomenon; in response to detecting or sensing the first predetermined physical phenomenon, cause the electronic communication device to record an utterance received from a user; detect or sense a second predetermined physical phenomenon via the second proximity sensor without using key elements of the electronic communication device, wherein the second predetermined physical phenomenon is representative of an intent to further control the operation of the speech recognition engine; in response to detecting or sensing the second predetermined physical phenomenon, cause the electronic communication device to cease to record the utterance; and provide the recorded utterance to the speech recognition engine for operation thereon; wherein the utterance includes an activated portion recorded after the first predetermined physical phenomenon is detected or sensed but before the second predetermined physical phenomenon is detected or sensed; and wherein the operation of the speech recognition engine on the utterance is limited to the activated portion of the utterance. - View Dependent Claims (9, 10)
