I listened to the nabucasa and the special tweakers podcast and very interested in AI.
I currently use a vraag {queue} to my llm (cpu powered)
AI would be great in understanding you and your home in speech commands hass can probably not maintain for all speech variations.
Make this system work if the already programmed speech system does not understand it.
And if many llm Actions are used make the creation of proposing homeassistant speech automations.
That follow up speech commands nolonger require the llm. This will save power and wil work if the system is offline and a cloud llm is used. (Nabu casa hosting llm is an option i heared in the tweakers podcast)
