I have it set up, just not for voice. I thought the system was a bit of a server/system to host some compute but appears to be just a speaker and mic.
You need some sort of hardware that HA can connect to and use as a pipeline. The rudimentary one was an Atom M5stack Echo and it had a wakeword process on it that used openwakeword service on HA, and then shipped TTS and STT over the network from Piper and Whisper over Wyoming protocol.
That's a complicated explanation, but essentially you installed an ESPHome config on the Atom and it would find those services and then use it for spk/mic as a voice assistant pipeline.

Nabu Casa was putting out a voice satellite hardware, I'm not sure where that's sitting these days, they might have sold out of the production run. But there are a few others being built, you might find something that works for you. I think FutureProofHome youtube channel was coming out with one too.
