Can you manage your house with a local, no-cloud voice assistant? Mostly, yes.

The leaders of Home Assistant declared 2023 the Year of the Voice." The goal was to let users of the DIY home automation platform control Home Assistant in their own language." It was a bold shot to call, given people's expectations from using Alexa and the like. Further, the Home Assistant team wasn't even sure where to start.
Did they succeed, looking in from early 2024? In a very strict sense, yes. Right now, with some off-the-shelf gear and the patience to flash and fiddle, you can ask Nabu" or Jarvis" or any name you want to turn off some lights, set the thermostat, or run automations. And you can ask about the weather. Narrowly defined mission: Accomplished.
In a broader, more accurate sense, Home Assistant voice control has a ways to go. Your verb set is limited to toggling, setting, and other smart home interactions. The easiest devices to use for this don't have the best noise cancellation or pick-up range. Errors aren't handled gracefully, and you get the best results by fine-tuning the names you call everything you control.
