| Abstract: | Proposed in this paper is a novel speaker-independent speech recognition system, which is command-variable and suitable for realization based on embedded platform. Compared with traditional speaker-independent speech recognition system based on PC, our system is featured small storage and computation cost. The system is evaluated on several embedded platforms that are specially designed. According to the result of the evaluation, the feasibility of speaker-independent speech recognition system based on embedded platform is proved and the least requirement for the hardware is given. Then we analyzed the main problems and difficulties in the development of high performance speech recognition SOC (System On a Chip) from the point of technology, and pointed out some future works. |
