Techniques for providing speech recognition comprise the steps of processing a video signal associated with an arbitrary content video source, processing an audio signal associated with the video signal, and recognizing at least a portion of the processed audio signal, using at least a portion of the processed video signal, to generate an output signal representative of the audio signal.

Method and apparatus for audio-visual speech detection and recognition

In a first aspect of the invention, methods and apparatus for providing speech recognition comprise the steps of processing a video signal associated with an arbitrary content video source, processing an audio signal associated with the video signal, and decoding the processed audio signal in conjunction with the processed video signal to generate a decoded output signal representative of the audio signal. In a second aspect 6f the invention, methods and apparatus for providing speech detection in accordance with a speech recognition system comprise the steps of processing a video signal associated with a video source to detect whether one or more features associated with the video signal are representative of speech, and processing an audio signal associated with the video signal in accordance with the speech recognition system to generate a decoded output signal representative of the audio signal when the one or more features associated with the video signal are representative of speech. Speech detection may also be performed using information from both the video path and the audio path simultaneously.
