Is it likely that the new AI HAT+ 2 will be able to run the AI and speech-to-text for use with things like the Home Assistant Voice Preview? https://www.raspberrypi.com/products/ai-hat-plus-2/
I bought one of these AI HAT+ 2 chips for my Raspberry Pi 5 but I'm fairly certain it's not actually used by HASS yet. It seems like the perfect kind of chip for this use case, all on board the same device as HomeAssistant itself.
