Abstract
A method and system for utilizing multiple speech recognizers. The speech system includes a port through which an input audio stream may be received, at least two recognizers that may convert the input stream to text or commands, and a combiner able to combine lists of possible results from each recognizer into a combined list. The method includes receiving an input audio stream, routing the stream to one or more recognizers, receiving a list of possible results from each of the recognizers, combining the lists into a combined list and returning at least a subset of the list to the application.
