Sir, I'm Patty Kotta, I want to develop a MATLAB program for reading a .wav file randomly from a group of .wav files. If anyone know the program , please send me & i'll be very thankful to you.
Your's Faithfully

No full code, but the hint to use the commands DIR, RAND and WAVREAD.
With DIR, you can receive all WAV files in a certain diretory. If you design a randon number so that it spans over the number of all files, then you just have to import them.

List = dir(fullfile(PathName, '*.wav'));
Index = randi(length(List), 1);
File = fullfile(PathName, List(Index).name);
S = wavread(File);

I thought you were in favor of coaching vs. providing code ;-)

Hello, I was searching for the same problem as above and I saw your answer. I already wrote a program to discriminate an audio (10 words speech) and used audiowrite to save each of the words individually as .wav files. Now I am trying to create random sentences with that 10 words but when I use the code that you suppied, It returns only a word, not a sentence. Do you have any idea to fix this?
If you provide your code, fixing it is much easier. A bold guess:
List = dir(fullfile(PathName, '*.wav'));
Index = randperm(numel(List));
for k = 1:numel(List)
File = fullfile(PathName, List(Index(k)).name);
S = wavread(File);
... So what do you want with the loaded data?
end
Note that wavread is not available anymore in modern Matlab versions. Use audioread instead.

Thank you. When I use that code as
List = dir(fullfile('C:\Users\hp\Desktop\Words', '*.wav'));
Index = randperm(numel(List));
for k = 1:numel(List)
File = fullfile('C:\Users\hp\Desktop\Words', List(Index(k)).name);
S =audioread(File);
sound(S,fs)
end
It sounds 3 words out of 10 at the same time, not in the order, unfortunatelly..
