You mean the voices processed through a VOCODER device. Back in the 70s, Vocoders were expensive machines. Nowaday, you can use a software called ORANGE VOCODER, distributed by Steinberg I think... It works as a simple VST software device which you can open and save within your CUBASE VST project.
I think it works quite well for a software device, and will transform audio tracks just as you described. Good luck have fun!
