[Feature Request] Upgrade Speech-to-Text to Coqui STT

[JRMeyer]

Hi there 👋

I'm not sure if this project is still maintained, but Mozilla's DeepSpeech isn't (mozilla/DeepSpeech#3693).

It would be a pretty small lift to upgrade to 🐸STT for the speech recognition, and the quality has very much improved:)
