Abstract
The method of the present invention is comprised of the steps of locating an error within a recognition hypothesis. A repair hypothesis is generated for the located error from a secondary input signal. At least a portion of the recognition hypothesis is correlated with the repair hypothesis to produce a new hypothesis for the located error. The located error is replaced with the new hypothesis. It has been determined that when the primary and secondary input signals are cross-modal, the chances that the error will be repeated are so low that the correlation step becomes optional.
