A lot of voice feminization tutorials talk about stuff like "resonance", "vocal weight", "false vocal fold control", but is there software that can take a voice recording and do a numeric breakdown of the voice along those axes?
The reason I'm interested in this is that I think such a tool would be useful for voice training because then you could create a "voice diff" tool: you take a recording of a desired target voice and then a recording of your own voice and the software does a breakdown of the two voices and displays the "diff" between the two voices to suggest what you should focus on fixing.
All of the tools I've found so far can only analyze pitch.
