Can someone help me with my video/computer problem?

I am an actor and I put on DVDs in my computer and act the scene out by studying the actors. I don’t know if this can happen. But, is there any way, that I can shut the woman’s voice but hear the man’s. So it’s like he is talking to me and I am responding. It’s like a karaoke. Something you hear the rapper in the background sing but you don’t hear the woman. Is that possible? Any programs that I can use? THANKS:)
