Can I get true “anonymous privacy” by changing my voice through audacity? And by that I mean making my voice sound as something else (maybe synthetic) with no possible recovery of the original.
and
If yes, which would be the steps to follow for that?
I hope I’m in the right place to ask this, and if I am, thanks in advance.
Please read Koz’s reply. You can reverse your words, but someone else can reverse that to get your words back. You can use voice changing plugins (I don’t know good ones for Linux) but people who know you will still recognise your delivery and cadences.
If this is for a legal experiment, I recommend consulting your lawyer.
It isn’t for legal porpuses, I won’t go to jail if someone could get my voice back, but if you would have to say the hardest change to recover, which would be it?
I’d advice running your text multiple times through Google Translator, then using a speech synthesizer.
Can’t guarantee you that it’ll work, but that shold seriously mess up the way you composed the text, probably partialy distorting it beyond intelligibility.
