Patent Images
1. A speech recognition system comprising:
- user interface logic configured to provide speech signals indicative of user speech;
speech recognition logic, responsive to processing parameters, wherein the processing parameters have an associated induced computational loading of a processor and an associated accuracy of speech recognition;
computational load-adjusting logic, responsive to a processor load variable representative of the computational loading of the processor, to adjust said processing parameters and thereby adjust computational loading of the processor and the accuracy of speech recognition, wherein the speech recognition logic includes logic to generate one or more sets of hypotheses that represent potential matches to speech signals and the computational load-adjusting logic includes logic to identify via the processing parameters the hypotheses to be used by the speech recognition logic.

Abstract
A speech recognition system includes a user interface configured to provide signals indicative of a user'"'"'s speech. A speech recognizer of the system includes a processor configured to use the signals from the user interface to perform speech recognition operations to attempt to recognize speech indicated by the signals. A control mechanism is coupled to the voice recognizer and is configured to affect processor usage for speech recognition operations in accordance with a loading of the processor.
