Hi!

As personal data protection legislation grows I'm in need of making part of my lecture records depersonalized. There are several students in the recording and their voices should be scrambled to make it more-or-less impossible to identify, yet to be understandable. Are there any tools to do this on a PC? Any 'scramble' plugins for Wavalab?

I hope my post is understandable

As far as I know, in the US, a lecture hall is considered an open forum and therefore, there is no privacy expectation.

Maybe I should have put more details: the lectures are closed forum held in Europe, and there were strict policies to students input (it is a psychological school, so some questions concern the students themselves or the patients). So the considered solution is to combine data censorship and voice depersonalization to make the recordings available to other students.

I would seek legal advice to determine if you need do this first. If you do, I am sure there is a way to do it. But first, is there the need?

You could toy with some of the vocoders that are out there.

It is very understandable. I apologize that the replies up to know have been very unhelpful. I know how frustrating it can be asking a question and not getting a straight answer. To answer your question yes you can use your pc to do it.

The easiest way you can achieve changing voices is with a wave editor program. Some programs Like the one provided with NERO actually have an option for voice modification. It does a very good job. I have done this to my own voice and people couldn't tell it was me.

I hope that helps. Let us know how it turns out.

Thank you, I will search for a vocoder plugin...
