| description | The invention relates to the field of Chinese voice study of hearing-impaired children. The three-dimensional electromagnetic pronunciation recorder is used for obtaining a basic acoustic parameter u1, a tongue position acoustic parameter u2, a lip tongue motion parameter u3 of a plurality of normal persons and listening-barrier children reading linguistic data, and a primary evaluation index anda secondary evaluation index of the fuzzy comprehensive database are established. The distance from each characteristic parameter of the secondary evaluation index of the hearing-impaired children tothe characteristic parameter of the normal person is taken as a membership function. Six scoring levels are set, and a judgment matrix is established, and the weight of each characteristic index is calculated through an entropy weight method. By means of M(+) operator, the secondary evaluation index score is obtained. By using the distance standard deviation from each characteristic parameter of the primary evaluation inde |
