A Reliability of Speech Interface in the Operation of Electric Power Systems

To support the routine operations of electric power facilities, a telecommunication system designed with fail-safe features was developed using speech interface. The system was installed in the field offices of an electric power company for field testing. And we collected many speech data, HRA-ET (Human Reliability Analysis-Event Tree) is used and system reliability was evaluated. As a result, we were able to get the visibility of thing that speech interface technology is applied to the field of operation of electric power systems. This paper describes a result evaluating reliability of the speech interface technology in the field of operation of electric power systems.
