Abstract
Automated capture of an uttered alphabetic character is provided by using an input, beyond the uttered alphabetic character, to disambiguate an incorrectly captured character. The input is an indication of a telephone key representing the uttered alphabetic character. The indication can be a dual tone multifrequency signal or an utterance of the number of the telephone key. Alternatively, the input is an indication that the incorrectly captured alphabetic character differs from the uttered alphabetic character.
