The present invention enhances directory assistance automation by searching traditional directory assistance databases with independent listing and locality queries. Initially, a caller's speech responses from a directory assistance inquiry are individually converted to independent listing and locality search queries. The listing and locality queries are determined by processing the caller's speech responses using a defined speech recognition grammar. The listing and locality queries are used to search a directory assistance database. Once the listing results are returned from the directory assistance database, the records in the listing results are analyzed to select a number for the caller's directory assistance request.
