Voice assistants stopped working since 2024.12 upgrade

Configuration Voice Assistant
1

Ever since I upgrade to 2024.12 my esp32 voice assistants quit working. I rolled back to 2024.11.3 but did not help. I uninstalled all the Wyoming protocols and reinstalled them still no luck. I finally figured out when the esp32s start they get to this point.

If I go to voice assistant and just select update I get to this point.

The strange thing is streaming wake word will work “okay Nabu” but the microwake word will not “Hey Jarvis” Not sure where to go with this next any ideas?
I’m thinking of trying a clean install on a new machine and see if the problem goes away on that.

Same here. Somebody please fix this.

I also have this problem. Not with ESP32, but with PI based assistants. 2 devices, worked fine for 2 months or so and suddenly stopped working completely.

UPDATE - Correction:

I apologize for the version confusion in my original post. Here are the correct versions:

  • Broken version: Home Assistant 2025.12.0 (released December 3, 2025)
  • Last working version: Home Assistant 2025.11.3

The issue: Voice assistants (microWakeWord) stopped working after upgrading from 2025.11.3 to 2025.12.0.

WORKAROUND that worked for me (Docker/Container installation):

bash

# 1. Downgrade
docker compose down
# Change image to: homeassistant/home-assistant:2025.11.3
docker compose up -d

# 2. Wait ~30 seconds

# 3. Upgrade back
docker compose down
# Change image to: homeassistant/home-assistant:2025.12.0
docker compose up -d

Voice assistant works again after this downgrade/upgrade cycle.
