When a company's interactions with its customers via telephone 
                can be shown to have any amount of similarity between each telephone 
                call, there is opportunity for significant cost savings by using 
                a computer to help aid the speech aspect of that interaction. 
                Systems built to capture those cost savings are called "telephony" 
                systems. Examples are corporate help desks, reservations desks, 
                information lines, etc. 
              Telephony, then, is a fancy word for speech applications which 
                use the telephone as some part of the system. The use of the term 
                historically precedes the arrival in the marketplace of desktop 
                computer based dictation systems.
               Telephony systems share with office dictation applications the 
                technological issues of dialogue design and recognition accuracy. 
                They add, however, the technological issues of telephone call 
                answering and processing and often require additional hardware 
                to handle that electronic environment. 
              Telephony systems leave a bad impression in the public mind when 
                little care is directed towards making life easier for the customer 
                but lots of effort is spent making life easier for the company 
                agent on the other end of the line.
