MERGING OF LANGUAGE MODELS FROM TWO OR MORE APPLICATION PROGRAMS FOR A SPEECH RECOGNITION SYSTEM

A speech recognition system operating on a computer system, which uses a single speech recognizer for all of the currently running application programs and provides a way of efficiently determining the proper destination application program for recognized speech. The speech recognizer uses a language model formed from the merging of the language models from two or more application programs. The merged language model includes data values indicating which application program's language model was the source of the language model elements so that when those elements are recognized, recognition results can be directed to that application program.
