We have developed a speech synthesis system based on the speech production process. In the system, control parameters for the vocal tract shape and vocal cords are interactively set in order to produce speech output. Such an intuitive system is useful not only for speech research but also for teaching materials in speech science. In this paper, a network-based articulatory speech synthesis system has been developed for distance education. In order to develop a Web-based articulatory speech synthesis system, a stand-alone type system previously developed was modified by using the program language, Java. Preliminary experiments showed the effectiveness of the system as a teaching material.
