Toward translating Indonesian spoken utterances to/from other languages

This paper outlines the National Institute of Information and Communications Technology / Advanced Telecommunications Research Institute International (NICT/ATR) research activities in developing a spoken language translation system, specially for translating Indonesian spoken utterances into/from Japanese or English. Since the NICT/ATR Japanese-English speech translation system is an established one and has been widely known for many years, our focus here is only on the additional components that are related to the Indonesian spoken language technology. This includes the development of an Indonesian large vocabulary continuous speech recognizer, Indonesian-Japanese and Indonesian-English machine translators, and an Indonesian speech synthesizer. Each of these component technologies was developed by using corpus-based speech and language processing approaches. Currently, all these components have been successfully incorporated into the mobile terminal of the NICT/ATR multilingual speech translation system.
