OpenAI Whisper Deepgram transcription bot for Mumble.

• an account on deepgram and an API key from it
• go (i'm on 1.19.4)
• openssl
• (see go.mod)

Warning: this thing is quite unoptimized and will murder your credits even when you aren't speaking! it starts a new transcription sesion for every speaker!

# (Generate cert)

if you're using nix, you can enable the glorious direnv (perhaps in your home-manager config!) along with lorri, run direnv allow and your direnv-compatible editor should pick up on the env changes and use the gopls binary specified in shell.nix -- it also puts openssl and go in PATH.

i did kinda like it but there's a bunch of post-processing to do and whisper.cpp runs on CPU-only, 4 threads or something.

i saw deepgram on a zack freedman youtube video and the thing just fucking works except for little-endian u16s being a weird choice.

i hope soon enough we'll have something that fits nicely on a raspi and can do all the things with like, 40% resource util.
