Abstract
A method and apparatus for establishing a telecommunications call connection in response to a phrase uttered by a caller. Data for the caller is stored in a data base shared by a plurality of switching systems. The data comprises a plurality of phoneme strings, each phoneme string corresponding to the phonemes for a phrase uttered by the customer during the training phase and a telephone number corresponding to the utterance. When the caller subsequently uses the service his/her utterance at the time of use is compared to the phoneme strings stored for that customer to establish the best match and thereby identify the telephone number.
