Greets, @ajvest!
I do the audio editing for the #gridcoin community hangouts, and heard about this initiative. We were trying to brainstorm a method for you to pay people per speaking time on track, etc... obviously we would use it too. lol
I have been scouring for some code related to finding JUST voice on an audio track... but it just doesn't really... exist yet. It would apparently be quite lucrative as well, seeing as phone companies could use it to lower bandwidth usage.
I have found a couple of almost promising examples of some code to put together. Hit me up if you're interested! :D
