Abstract
Abstract The present invention provides an apparatus and method for verifying address identifiers over a telecommunications network by first storing a plurality of zip codes in a database. A corresponding list of address identifiers is created and stored for each zip code. After receiving a spoken zip code from a user, the corresponding list of address identifiers is retrieved. Once the list of address identifiers is retrieved, a plurality of choices for at least some of the address identifiers is created. These plurality of choices contain words that rhyme with or sound like other address identifiers located in the retrieval group of address identifiers.After the system receives a spoken address identifier from the user, the system queries the database for a match between the spoken address identifier and the stored address identifier. The user is then prompted to verify that the system accurately recognized the spoken address identifier. However, if a plurality of choices was created for the matched address identifier, the user is presented with the plurality of choices to select from instead of the matched address identifier. Whether the address identifier or the plurality of choices is presented to the user, the user is requested to verify that the system correctly recognized the spoken address identifier.

Claim 10
Independent Claim
152 words
A method of recognizing speech data comprising the steps of prompting a user to enter a first set of DTMF numeric data via a keypad of a communications device; querying a database to match said first set of numeric data to an entry in said database; prompting said user to enter a second set of DTMF numeric data via said keypad of said communications device; comparing said second set of numeric data to pre-stored range of digits; retrieving from said second database a pre-stored set of sequence of speech patterns using said first set of DTMF numeric data as a search key for such retrieving; prompting said user to provide speech data via said communications device; and in response to receiving said speech data from said user, comparing said speech data to said sequence of speech patterns using said second set of DTMF numeric data as input to recognize said speech data.
Claim 11
Dependent Claim
