Abstract
A method and apparatus for recognizing an input identifier entered by a user. A caller enters a predetermined identifier through a voice input device. A signal representing the entered identifier is transmitted to a remote recognizer, which responds to the identifier signal by producing a recognized output intended to match the entered identifier. The present invention then generates a set of option identifiers, each option identifier having a possibility of matching the input identifier. The set of option identifiers is then reduced to a set of candidate identifiers by eliminating those option identifiers that are not found among a set of stored reference identifiers. The present invention selects a match for the input identifier from the set of candidate identifiers.
