Experiences using a local voice assistant with LLM with HomeAssistant?

Has anyone out there hooked HomeAssistant up to a local LLM? I'm very tempted:

• Alexa integrations fail often. HomeAssistant integrations tend to be rock solid.
• Alexa is rule/pattern matching based. LLMs can understand natural language fairly well. The "magical incantations" required by Alexa are awkward.

Other than the software, the device side seems challenging. There are $50 fully-baked POP devices. I'm less sure on the DIY front.

Also, I desperately want my house to speak to me in the voice of the NCC-1701D computer. I've read enough now to know this should be achievable with a modicum of effort via OSS voice cloning tools or training a new model (same difference except "voice cloning" seems to often refer to doing this without training a whole new model?).

Thoughts? Experiences?

I've seen several pages that have led me to conclude this is tenable:
