系統采用凌陽SPCE061A 單片機作為語音識別系統的主控芯片。通過硬件電路
設計和軟件代碼部分成功的設計并實現了一種具有語音識別功能、語音提示(語音合成)及語音回放(語音編碼記錄)功能的嵌入式語音識別系統。語音識別模型采用（DHMM)離散隱馬爾可夫模型，利用Baum-welth 重估算法、前向后向算法、viterbi 算法來完成語音模板的訓練和語音識別的任務。

Design of Speech Recognition System Base on SPCE061A Yingfeng fengyufen Abstract: The system selects SPCE061A as MCU of speech recognition system. Through the hardware circuit design and the software code, design and realize the embedded speech recognition system which contains functions of speech recognition, voice prompt (speech synthesis) and audio playback (speech coding record). The discrete hidden markov model(DHMM)is adopted，Baum-Welth reestimation algorithm, forward-backward procedure and viterbi algorithm is utilized to train and recognize the speech signal.
