In the paper we present a speech training aid (a visual feedback system running on a standard multimedia PC) designed for hearing impaired people. The performance of the system has been evaluated both in simulated and field tests. In the former, a group of non-deaf persons tried to learn pronunciation of an unknown exotic language using entirely the visual information provided by the system. The progress of learning was measured on several levels by a speech recognition tool and yielded a significant improvement. Recently, a similar set of experiments is conducted with a group of deaf children.
