摘要
论述了声纹识别技术的基本原理,采用DSP及其他可编程芯片设计出声纹识别系统的硬件部分,阐述了其结构及工作原理。基于隐马尔可夫模型为算法,以线性预测倒谱系数和Mel频域倒谱系数为特征矢量进行了系统仿真。结果表明,在结合使用两种倒谱系数及差分时,系统具有较高的识别率。
The fundamental principle on technology of voiceprint recognition was discussed.By using DSP and other programmable chips,the voiceprint recognition system together with hardwares was designed,also the structure and working principle of this system were stated.Hidden Markov model was taken as the modeling algorithm and two feature vectors as far as the Mel cepstrum coefficient and the linear prediction one were concorned,the system simulation was done.The result expatiated when the combination of two cepstral coefficients and their difference were used,the system was of high speech recognition rate.
