Small footprint language and vocabulary independent word recognizer using registration by word spelling

摘要

A phoneticizer converts spelled words or names into one or an n-best number of phonetic transcriptions. The n-best transcriptions may be generated from a single transcription using a confusion matrix. These n-best transcriptions are then transformed into hybrid units. Preferably only the most frequently encountered units are stored as syllables, with the remainder being stored as smaller units such as demi-syllables or phonemes. Voice input is then used to rescore the n-best transcriptions and these are stored preferably as speaker-independent, similarity-based hybrid units concatenated into a string representing the spelled word.
