| Abstract: | This paper has analysed the question with transformation of characteristic lower dimension and characteristic Robust quality. It is certified by practice that lower dimension means based on CDN distribution suits the speech recognition of independent speaker. It has outstanding advantages. The problem of characteristic Robust quality can be solved by adjusting model parameter and using learning model with voice confusion. |
