SPEECH RECOGNITION VOCABULARY INTEGRATION FOR CLASSIFYING WORDS TO IDENTIFY VOCABULARY APPLICATION GROUP

A method for vocabulary integration of speech recognition comprises converting multiple speech signals into multiple words using a processor, applying confidence scores to the multiple words, classifying the multiple words into a plurality of classifications based on classification criteria and the confidence score for each word, determining if one or more of the multiple words are unrecognized based on the plurality of classifications, classifying each unrecognized word and detecting a match for the unrecognized word based on additional classification criteria, and upon detecting a match for an unrecognized word, converting at least a portion of the multiple speech signals corresponding to the unrecognized word into words.
