I'm developing software for forensic linguistic research. One of the things that I'll need to do is show if a person is nervous or worried. Or if a sentence is a statement or a question (the intonation pattern and frequency).
As a scientist, I would like to just show the signal itself, with the relevant aspects highlighted, but the user may not be able to make much sense of that.
I know you cannot probably solve this issue -- but maybe you experts know of some good inspiration of speech signal representation.
