SINZ

So I am trying to make my LSPDFR game as realistic as possible and I got into playing around with vocal dispatch. I was then wondering about using a mod like vocal dispatch but to use it to ask for license and registration,preform frisks,ask questions etc. I did some looking and saw that people tried doing this in GTA IV in 2014 and 2015 using VAC but not much was posted about it and I coudnt find anything recent on the topic. If anyone knows how to use VAC to do this or a different mod that can preform the actions I described then please comment. Thanks.
The VAC I am talking about is from http://www.dwvac.com/

I would love to have all ai driving real cars!!! It would make the game feel that much more realistic. Please let me know when you finish it will be an amazing project to play with!
