Automating Operator-Assisted Calls Using Speech Recognition

Thomas B. Schalk

Voice Control Systems

A speech processing system has been developed that is capable of automating a number of operator services over the telephone network. This system, called the VoiceGateway System (VG), is equipped with the following capabilities: speech recognition, speech output, speech storage, DTMF (touchtone) tone detection, remote database access, and telephone switching system communication. The specific application addressed in this paper is the automation of operator-assisted telephone calls. Operator-assisted calls are those that require telephone operator intervention to complete. These include collect calls, calls billed to a third number, creditcard calls from nontouchtone phones, and person-to-person calls. A detailed description of the way in which the VG interacts with humans to process these calls will be presented with an emphasis on the speech recognition requirements for this application.
