A method of redirecting a directory-assistance call includes receiving a directory-assistance request from a caller, determining via a free directory-assistance service whether information corresponding to the directory-assistance request is available, responsive to a determination that the information is available, presenting, to the caller, the information free of charge to the caller and, responsive to a determination that the information is not available, redirecting the directory-assistance call to a chargeable directory-assistance service.

Method of and system for automatically switching between free directory assistance service and chargeable directory assistance service

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.
