Sound recording anonymization I want to study stress based on sound recordings. However, there are many concerns about keeping the identity of the recorded persons anonymous.
I want to keep intensity and spectral contents intact but I am not interested in the message or the identity of speakers.
I thought about time reversing the recordings, but this could be easily undone by someone.
Do you have any suggestions for this purpose?
I don't really think there's one:
You seem to be in the process of figuring out what about a piece of audio signifies stress.
As long as you don't know that, you can't erase any identifying information from it without standing a high probability of also erasing your &quot;stress&quot; information.
