INTRODUCTION The learning course of language is a continuous progress of practice. The language learning for normal people is naturally, which is spontaneously corporation with hearing-feedback. The normal learning mode is not suitable to the hearing impairers. The hearing impaired are consequently losing the speech ability. Language is the most important social behavior to human being, and it is the most convenient and efficient communication tool. As a result, the researchers continuously devote themselves in developing the special training tools for helping the hearing impairer to learn speech. In the literatures, the most efficiency tools were to use the visual-feedback to replace the hearing-feedback that the hearing impairers lost [1-5]. The language learning is constantly progressing anytime and anywhere for normal person. For the hearing-impaired children, the speech learning is usually limited in special education institutes, and is directed by professionals. The period in the institute is just a little part of their day life. In most time, the children are companioned with their parents who are usually not professionals. The learning course of the children is consequently interrupted, and results in low learning efficiency. In Taiwan, there is severe deficiency in the teaching manpower for the hearing impairers. The learning interruption problem is then especially grave in Taiwan. The study proposes a teaching assistant system. This is a multifunction assistant system, which is for professional teaching and training, and parent teaching assist. Especially, the system assists the speech education and practice of the hearing-impaired children, when they leave the education institutes. As a result, the problems in manpower deficiency can be reduced, and the interruption problem is solved.
