A little while ago, while watching a foreign and not-so-known (in my country) TV show, for a moment I lost focus and started thinking if it would be possible for only two people, a man and a woman, to record their voices for ALL characters (respecting the gender, of course) and modify them somehow (preferably with a reusable preset) to create a fully functional voice cast and actually dub the whole show.
I have absolutely zero knowledge on the matter but I had this curiosity with for afewdays already but I couldn't find much about it (probably because I'm using the wrong terms...)
In a positive case, could it be done by software only? If so, which one?
