Abstract
The present invention is a system that uses a limited text input entry device to narrow the possibilities for the selection of a phonetically based name used in a voice dialer. The user enters a DTMF signature of a name using only one key for each letter of the name. The signature is used by a dictionary to generate likely possibilities for the word. The user is asked whether the name is the name entered via playing the name to the user. If the user confirms the choice, the phonetic representation is stored along with a corresponding telephone number. If the played word does not match, a word generator generates additional likely possibilities from the signature. A speech recognizer picks the best representation from the dictionary and generator words based on a spoken version of the name. A first name and last name procedure, in which the first and last name signatures produce separate candidate lists, is used to provide an entry to an address book for voice dialing.
