Patent ID: 7340392

Claim:
A method of recognizing a voice command, comprising: receiving a voice input; determining a number of sound fragments to be processed in a first set of sound fragments of the voice input by: monitoring a load of a first processing system and a load of a second processing system; and determining the number of sound fragments of the voice input based on the load of the first processing system and the load of the second processing system, wherein the number of sound fragments of the voice input is increased when the load of the second processing system exceeds a predefined threshold; using the number of sound fragments, determining, by the first processing system, whether the first set of sound fragments from the voice input matches with a first set of sound fragments of a voice command; and if the first set of sound fragments matches with the first set of sound fragments of the voice command, then determining, by the second processing system, whether one or more remaining sound fragments matches with one or more remaining sound fragments of the voice command.
