Any free software to make speech sound different without making it "robotic"?
I am looking for a software that can alter your voice in a way, that the output sounds more or less normal. But the result should not have any information about my voice. I would prefer a free software like audacity for that. When I looked for audacity I mostly found sites that suggested changing the pitch. But i want something that really is irreversible. On the top of that I want a free software that can do this (if possible). What are the main-points that are used for voice-recognition? What are audio-effects that make voice-recognition difficult or impossible? Are there free programs that can do this?
I thought of something like this:
In the end you should not be able to differentiate beetween a man, a boy, a woman, a girl, a high voice, a deep voice etc.
