You could start by reading the help for MATLAB's conv function:

What exactly are you trying to do? "Extract" could mean many things. If you are trying to classify words using convolution of speech recordings, then you should probably understand that this is likely to perform very poorly. If you are trying to "extract" the words from a noisy background, then this would be a very different task. If you mean something else, then it will be different again.
