MATLAB语音识别

基于MATLAB的使用hmm算法实现0到9是个数字，以及几个汉字的语音识别系统，并设计了gui界面。

function y=barkquzao（x）
 TPTR0=‘rigrsure‘%自适应阈值选择使用Stein的无偏风险估计原理。
%  TPTR1=‘heursure‘%使用启发式阈值选择。????????
%  TPTR2=‘sqtwolog‘%阈值等于sqrt（2*log（length（X）））.????????
%  TPTR3=‘minimaxi‘%用极大极小原理选择阈值。?
  THR（1）=thselect（xTPTR0）
%  THR（2）=thselect（xTPTR1）
%  THR（3）=thselect（xTPTR2）
%  THR（4）=thselect（xTPTR3）
