Dialects are often used in hospitals and nursing facilities in local areas. Most of the patients and nursing facility users express their pain or discomfort using their own dialect. But sometimes they are very difficult to understand, especially for foreigners. We are developing online Yamagata dialect referencing. The character input method is based on dialect expression dictation answer variations given by foreign students. When foreign nurses or care-givers cannot understand complicated dialect expressions, the system we are devising allows them to access unknown and uncertain dialects using keywords they can pick up comparatively easily.
