PROTS (from PROnunciation Training System) is an English pronunciation practice system which applies speech analysis technology to language learning, PROTS was developed by Kawai Musical Instruments Mfg. Co., Ltd. under the guidance of Professor Hisako Murakawa of the International Budo University. The system is composed of texts and laser disc software which form the basis for the systematic study of pronunciation, from single vocabulary items to dialogs, and an analyzer hardware system which subjects the student's pronunciation to computer voice analysis, allowing visual and aural checking of accuracy. Both the learning materials and the analyzer hardware are appropriate for use in language labs as well as for independent study. The system is organized so that it can be used effectively by students at all levels, from junior high school to college and private language schools. In this paper we would like to introduce the background and basic principles of the system, explain its design and function, and then present some examples of its use in the study of pronunciation.
