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。
By analyzing the characteristics of speech characteristic parameters and the basic method of speaker recognition, linear prediction cepstrum coefficient as the feature extraction algorithm and hidden Markov model as the modeling algorithm, the use of Sunplus MCU as the hardware platform to achieve the voice-activated lock Voice control function. The experimental results show that the system performance is stable and the recognition effect is good.
