function code = train(traindir, n) 
% 计算wav文件的VQ码码本 
% Speaker Recognition: Training Stage 
% 
% Input: 
%       traindir : string name of directory contains all train sound files 
%       n        : number of train files in traindir 
% 
% Output: 
%       code     : trained VQ codebooks, code{i} for i-th speaker 
% 
% Note: 
%       Sound files in traindir is supposed to be:  
%                       s1.wav, s2.wav, ..., sn.wav 
% Example: 
%       >> code = train('C:\data\train\', 8); 
k = 16;                         % number of centroids required

    file = sprintf('%ss%d.wav', traindir, i);            
    disp(file);

    code{i} = vqlbg(v, k);      % Train VQ codebook
