I made a little gui for it.
(Or rather, ported my little voice typing gui to use Whistle/Needle instead of Parakeet. Only had to change like 2 lines!)

Seems to do roughly as well as parakeet (both speed and quality) so far.
I use it on Linux. I think it's cross platform but I haven't tested it. Would love to know! Should be trivial (2 mins of Codex) to get it working on other OS if not.
