How to compare two audio data?

I will record my own voice and save them as wav files on my computer. Later I will talk, and the computer should match my voice command with existing / pre-recorded wav files.

Question: How to check two audio data are equal or is there 80% match between two audio?

if(audio1 == audio2)
   DO Task A
else if( audio1 is a bit similar to audio 2)
   DO TASK B
else if( audio1 (80% match) audio 2)
   DO TASK C
end if
