Speaker verification

Hello,

I get a speaker verification matlab code on the internet. But I can't understand all the lines. Can someone explain to me the following lines?

for i=1:3

    Speaker_name=Au_dir(i).name;
    Speaker_path=strcat(data_path,Speaker_name);
    Speaker_data=getInfo(Speaker_path, 'wav');
    len=length(Speaker_data);
    Speaker_mix=randperm(len);
    Speaker_data=Speaker_data(Speaker_mix);
    Speaker_train=Speaker_data(1:300);
    Speaker_intest=Speaker_data(301:len);

    All_data=getInfo(data_path, 'wav');
    all_len=length(All_data);

Thank you for your kind support.

What is "speaker verification" ? Is that Voice Recognition?

Hi, this code appears to be just reading the data from the .wav file for a particular speaker

Speaker_name=Au_dir(i).name;
    Speaker_path=strcat(data_path,Speaker_name);
    Speaker_data=getInfo(Speaker_path, 'wav');

I'm guessing that getInfo is not a MATHWORKS function. Is there a getInfo.m file in the code you downloaded?

Then, you get the length of that data and obtain a random shuffling (permutation) of the integers from 1 to the number of samples in the data.

      len=length(Speaker_data);
      Speaker_mix=randperm(len);

Then, you reshuffle the data based on that permutation. And create a training set of the first three hundred samples of the shuffled data and a test set of samples 301 to the end of the speaker's sample.

    Speaker_data=Speaker_data(Speaker_mix);
    Speaker_train=Speaker_data(1:300);
    Speaker_intest=Speaker_data(301:len);

Then it looks like it reads all the wav files in. I'm guessing to see if it can identify the correct speaker.

      All_data=getInfo(data_path, 'wav');
      all_len=length(All_data);

Does the getInfo() contains the functions related to speaker recognition?

Thanks Wayne for your answer! But there is no getInfo.m file in the code i downloaded.

can u please write the whole code....i urgently needs a project on speech recognition
