After way too many months, I finally have a USB speakerphone working as a voice control device on Home Assistant. I think this is a far better implementation than the ESP32 based approaches which are the standard. While those are probably great for satellites, they usually have very poor audio and microphones. This one has much better audio properties, and it's plug and play (in theory).

Set up on this one is dirt simple (if it works). Plug in the device. Set up openwakeword and Assist Microphone in your addons, get them into Wyoming, add the wake word in your Voice Assist pipeline, and that's it.

I'm using a Kaysuda USB Speakerphone (SP300U)
