Abstract
The present invention comprises a system and method for speech recognition utilizing a merged dictionary, and may include a recognizer that is configured to compare input speech data to a series of dictionary entries from the merged dictionary to detect a recognized phrase or command. The merged dictionary may be implemented by utilizing a merging technique that maps two or more related phrases or commands with similar meanings to a single one of the dictionary entries. The recognizer may thus achieve more accurate speech recognition accuracy by merging phrases or commands which might otherwise be erroneously mistaken for each other.
