As the quality of current synthetic speeches haｓ been improved, they have been widely used in various fields, such as, the announcement system of public transportation, traffic information, voice guidance, interactive voice response system and so on. Synthetic speeches have also been utilized in the field of foreign language learning. They have been integrated into electronic dictionaries and CALL softwares. It is expected that synthetic speech have a great potential for language learning systems. Meanwhile, when we consider creating audio materials in foreign language teaching, it costs teachers time and effort to create their own materials by handling authoring tools, recording and editing sound files. The utilization of the tools may need high computer skills. Furthermore, a lack of native-speaker environment strongly affects the creation of listening materials. In view of these situations, utilizing synthetic speechcs in listening materials may improve the situation mentioned above. In this paper, we explore the potential of synthetic speech in foreign language learning. First, we look at the basic approach of text-to-speech synthesis, next, we review the current state of integration of synthetic speech in CALL applications. Then we consider how we should exploit the strengths of speech technology while working around its limitations. In the discussion, we identify directions of future research for better use of synthetic speech.
