matlab实现声纹识别,通过提取声音信号的MFCC特征,然后形成特征向量,通过训练语音,对测试语音进行识别,可以识别训练库内的声音,也可以识别出训练库外的声音

function f=enframe(xwininc)
%ENframe split signal up into (overlapping) frames: one per row. F=(XWININC)
%
% F = ENframe(XLEN) splits the vector X up into
% frames. Each frame is of length LEN and occupies
% one row of the output matrix. The last few frames of X
% will be ignored if its length is not divisible by LEN.
% It is an error if X is shorter than LEN.
%
% F = ENframe(XLENINC) has frames beginning at increments of INC
% The centre of frame I is X((I-1)*INC+(LEN+1)/2) for I=12...
% The number of frames is fix((length(X)-LEN+INC)/INC)
%
% F = ENframe(XWINDOW) or ENframe(XWINDOWINC) multiplies
% each frame by WINDOW(:)
