I used following code for speech recognize. but it says Error using wavread (line 167). Not a WAVE file, when I run the speechreco​gnition('o​ne1.wav') code in command window. one1.wav is my audio wav file. what should I do for this.

function speechrecognition(filename)
%Speech Recognition Using Correlation Method
%Write Following Command On Command Window 
%speechrecognition('test.wav')

Please attach your .wav files

Also, which MATLAB version are you using, and which operating system?

Note: wavread() was removed from MATLAB a couple of releases ago; you should be using audioread()

[kamrul hasan]

use audioread instead of wavread
