Abstract:
1. A system for generating a dictation language model in speech recognition applications, comprising: a processor; memory operatively coupled to the processor; a detection component that identifies out-of-grammar (OOG) utterances, the OOG utterances are not recognized by context-free grammar (CFG) rules; a parsing component configured to identify a slot in the OOG utterances; a grammar generation component that generates a dictation language model by creating a new rule based in part on the OOG utterances, the grammar generation component configured to add a filler tag proximate to the slot to generate the new rule, wherein the slot is a dynamically adjustable list of text items, the slot references the rule to the list of text items, the slot being a direct object of the rule, wherein the filler tag represents an acoustic element in the OOG utterances, and the filler tag combines with the slot to create the new rule; a processing component that processes user utterances through the dictation language model before the CFG processes the utterances, the processing component further configured to communicate to a user all existing rules that contain the identified slot and receive from the user the user's selection of one of the existing rules; and a personalization component that updates old CFG rules with the new rule.
