TEDDI: open and extensible tool for designing telephone-based spoken dialogue systems

摘要

We have developed TEDDI, a design and development tool for telephone-based spoken dialogue systems. TEDDI consists of nine components, such as telephone control, speech synthesis, speech recognition, and two enhancing components. Using TEDDI, a dialogue system can be developed in a GUI environment, in fact, examined and executed. We have implemented TEDDI in an object-oriented language Ruby, and a designer can write an original function efficiently by using inheritance from a basic component. This paper describes TEDDI and its application to the development of a telephony voice collection system and a network information system.
