ABSTRACT:
A speech recognition system is disclosed useful in, for example, hands-free voice telephone dialing applications. The system will match a spoken word (token) to one previously enrolled in the system. The system will thereafter synthesize or replay the recognized word so that the speaker can confirm that the recognized word is indeed the correct word before further action is taken. In the case of voice activated dialing, this avoids wrong numbers. The token itself is not explicitly recorded; rather, only the lefemes may be recorded from which the token can be reconstructed for playback. This greatly reduces the amount of disk space that is needed for the database as well as provides the ability to reconstruction data in real time for synthesis use by a local name recognition machine.
