The Computer Vision Toolbox vision.VideoFileReader can specifically handle reading video and audio at the same time. It sounds as if you do not need the video; you might be able to read the audio using audioread(), but AVI is not certain to be supported for that.

Once you have the audio extracted from the file, you are dealing with Speech To Text; http://www.mathworks.com/matlabcentral/answers/?term=tag%3A%22speech+to+text%22
