Speaker-independent name dialing with out-of-vocabulary rejection

We propose a system for speaker-independent name dialing in which a name enrolled by a user can be used by other members in a family or co-workers in an office. We use speaker-independent sub-word models during enrollment; the recognized sub-word string is later used during recognition. We also present a mechanism for rejecting out-of-vocabulary (OOV) phrases. The best in-vocabulary (IV) correct and OOV rejection performance for other speakers is 90%/60% (IV/OOV) on a database containing eighteen speakers. If the orthography is known, the best performance is 96%/65%
