Abstract: An automated system places telephone calls to speech-based information systems, and interacts with the systems to retrieve information therefrom. The system employs a calling computer which uses speech recognition software to recognize the verbal messages generated by the information systems. A first embodiment of the present invention is designed specifically for calling bank information systems to verify accounts, checking transactions drawn on accounts, etc. This embodiment includes a bank database which contains all of the pertinent information necessary to navigate each of a plurality of bank's information systems through entry of appropriate DTMF tones. A second embodiment of the invention is employed for checking the status of lists of telephone numbers to determine whether the numbers have been changed or disconnected.
