A free, simple software that lets you sing into your microphone while hearing your voice in your speakers? - free simple dune buggy blueprints

Hello,
I am looking for a karaoke software, but had no luck finding what I want. Now I think I'll just play the songs on my computer, but with software that makes itself heard in real time into the microphone (to sing when adding some reverb / echo)
Is there a simple and free way?
Thanks
