Is it good? are the sounds realistic?

You'd think that for a program like this for the video about the software that there would be some demonstrations of how good it is, but instead there's synth music with one scream (and only using one setting)??? I guess the software can't be good if they aren't willing to demonstrate the features of how it changes the sound!...

whenever i go to games like gta 5 or lost arc. I have distortions in my morphed voice. sometimes there are distortions even without morp. more robots. but when I'm not in games, my voice is heard and understood very well. I've been looking for the cause and solution for a long time, but I couldn't find it, does anyone have the same problem?...

when i run voice doctor after voice check. it says appdata/learning/b11eac... encountered an error how can i fix this?

Why is my preference only generic，and you？
