Add ChromeOS speech-to-text as local STT engine

[vital wyvern]

Recently I managed to get the ChromeOS local STT engine (SODA (Speech On-Device API)) to work on an RPi4 with very impressive results. The RPi4 has plenty of power to do this, the transcription is real-time with very low WER and it has support for dozens of languages. I'd like to make an integration with HA and looked how it is done in https://github.com/rhasspy/wyoming-faster-whisper, but I could definitely use some input form people who have experience with this. A command-line client PoC is here: https://github.com/biemster/gasr.

Anyone interested in helping out?

Apparently @wise mulch already did this! In https://github.com/biemster/gasr/issues/26 you can find a wrapper:

and also for the TTS found in ChromeOS:

It would be much more useful to have that as add-on. 🙂

[vital wyvern]

You mean it can be selected here right @toxic isle ?

yeah that's the plan (although I thought that that was provided by goddade's repositories)

What languages are supported?

Thank you, no Czech language support 😞

[vital wyvern]

seems not unfortunately

[pallid bane]

So only offline STT engine is faster whisper which is slow and high WER for Czech

[toxic isle]

It's not... It's service, that works with Wyoming. It should be put into Docker container, and wrapped into add-on.

[vital wyvern]

so the wyoming server should be kept, but there is a home-assistant way of packing stuff in a docker container which makes it an add-on? (sorry I'm new to HA)

Exactly
