we paid for voicemod 3 , and it's amazing, it's a bit heavy and internet dependant , but gets the job done , and has a large community creating stuff for it we use it almost every day, zero issues More on reddit.com

I used morphvox for quite a while and really liked it. It did sometimes glitch and get robotty but I think this is mostly attributable to my pc at the time having only an i5-3550 and between a game, discord, streaming etc. all going at once there was a fair bit of competition for cpu cycles. Haven't installed it on my new pc yet, but might put it on later today since bow I'm thinking about it. There was also a fair voice delay for me, as well, maybe about 200ms, which made sharing video hard because I seemed out of sync, and occasionally would cause problems in conversations or in games where speedy communication is really important. I'm not sure if the significance of the delay was cpu related or not, but guess I'll find out later when I get home. Keep in mind, if you're planning on using a voice changer you'll still likely need to work on your inflection, foments, etc. to really get the most out of it. More on reddit.com

Cool. I guess, just be aware that your voice seems to be being recorded and saved somewhere that isn't your computer/apartment/house when you use it. More on reddit.com
