A Nios II Based English Speech Training System for Hearing-Impaired Children

We propose a novel feature system of language training for hearing-impaired childrenpsilas speech rehabilitation based on DE1 development board, which contains an on-chip system called uc/os. The system is imbedded with Nios II processors, which could make our system stable, portable and cheap. Considering the limited storage and calculation ability of imbed system, at the same time, and we recognize childpsilas voice by single phoneme, we use LPCC as eigenvector to judge the similarity between speakerpsilas voice and examplepsilas.
