*Important* Speech Jammer or Speech Delay

I was wondering if there was a way to do this on Mixcity 6 because I'm doing this for a project and it is important that I know how to do this. I've tried looking around almost everywhere but I have failed to find a tutorial on how to achieve the desired effect. I am serious about this so please reply with serious answers. You can e-mail me at dmtan95@gmail.com because this is my first time on the forums so I don't think I'll be visiting here too often. If you can help me achieve the effect that I'm looking for, I'm willing to pay money. Don't ask how much until you've actually written a tutorial or made a video for me.

Thank you.
