    • A modeless large vocabulary continuous speech recognition system is of the type that represents an input utterance as a sequence of input vectors. The system includes a common library of acoustic model states for arrangement in sequences that form acoustic models, wherein each acoustic model is composed of a sequence of segments modeles and each segment model is composed of a sequence of model states; an input processor that compares each vector in a sequence of input vectors to a set of model states in the common library to produce a match score for each model state in the set reflecting the likelihood that such state is represented by such vector; a plurality of recognition modules and associated recognition grammars, the modules operating in parallel and using the match scores with the acoustic models to determine at least one recognition result in each of the recognition modules, wherein the plurality of recognition modules includes a dictation module for producing at least one probable dictation recognition result, a select module for recognizing a portion of visually displayed text for processing with a command, and a command module for producing at least one probable command recognition result; and an arbitrator that uses an arbitration algorithm and a score ordered queue of recognition results together with their associated recognition modules to compare the recognition results of the recognition modules to select at least one system recognition result.
