摘　　要：通过分析语音特征参数的特点和说话人识别的基本方法,以线性预测倒谱系数为特征参数提取算法以及隐马尔可夫模型为建模算法,利用凌阳单片机作硬件平台,实现了声控锁的语音控制功能。实验结果表明,系统性能稳定,识别效果良好。　The features of voice-character parameters and fundamental speaker recognition methods are analyzed by using linear prediction cepstrum coefficient and hidden Markov model as modeling algorithms. The speech recognition control function is implemented by the hardware platform Sunplus MCU .The experimental results show that the designed system has high identity precision can achieve the request of safety-secrecy.
