Abstract: The embedded systems’ ability is not enough to run HMM-based speaker-independent continuous speech recognition algorithms, especially the search algorithm and the state likelihood computation. This paper proposes an embedded platform based on MPC5200 microprocessor, and implements a HMM-based speaker-independent continuous speech recognition system on this embedded platform. The experiments show that the real-time performance of this embedded speech recognition system is acceptable.

Key words: speech recognition, HMM, embedded system, MPC5200
