A sign language interpretation apparatus for performing sign language recognition and sign language generation generates easily read sign language computer graphics (CG) animation by preparing sign language word CG patterns on the basis of actual motion of the hand through the use of a glove type sensor to generate natural sign language CG animation, and by applying correction to the sign language word CG patterns. Further, in the sign language interpretation apparatus, results of translation of inputted sign language or voice language are confirmed and modified easily by the individual input persons, whereby results of translation of the inputted sign language or voice language are displayed in a combined form desired by the user to realize smooth communication. Also, candidates obtained as a result of translation are all displayed and can be selected easily by the input person with a device such as a mouse. Further, when a polysemous word is available, the word is displayed while being changed in its display form, and other expressions are confirmed and modified with the mouse.

Sign language generation apparatus and sign language translation

A voice coding system for separating and coding voice information into spectrum envelope information and voice source information, with the intention of compressing the amount of information for efficient coding of vocal audio signals through the control of the voice source information based on the fact that the spectrum envelope information and voice source information highly correlate with each other.
