Make sure maximal prompt + generation length <= 16 seconds (due to our limited compute, we had to drop utterances longer than 16s in training data). Even stronger models forthcomming, stay tuned!

+Be sure to first [setup your environment](#environment-setup).
+Without arguments, they will run the standard demo arguments used as an example elsewhere
