Development of a Simultaneous Interpretation System for Face-to-Face Services and Its Evaluation Experiment in Real Situation

We developed a simultaneous interpretation system for face-to-face services at shops, front desks, and so forth. The system supports interpretation between Japanese and English, or Japanese and Chinese speakers. It incrementally processes user’s continuous and spontaneous speech, and then incrementally produces interpretation results. We conducted a field test of the system to evaluate the “solved task ratio” for tasks including buying souvenirs, asking a bus route. As a result, we achieved the solved task ratio of 81%.
