Best open-source Voice assistants

The best self-hosted voice split in the c17.io catalog is Home Assistant Assist (Apache-2.0 — the published Alexa/Google Home path on a dashboard you already run), Open Voice OS as the maintained Mycroft-shaped runtime (ovos-core; Mycroft core is archived), openWakeWord for wake-word detection, and wyoming-openwakeword as the Wyoming protocol server Home Assistant documents. Cameras stay on /best/nvr-cameras. Signal-server is not a self-host product for users.

FAQ

Alexa or Google Home?
Same published stack — /replace/alexa and /replace/google-home. Home Assistant Assist if the house already runs HA. Open Voice OS if you want the Mycroft-shaped runtime.
Is this Ring or Nest?
No. Cameras are /best/nvr-cameras. This page is voice.
Will it speak every Alexa skill?
No. You get local intents you wire. Vendor skill stores stay behind.
Are these free?
Home Assistant core, Open Voice OS, openWakeWord, and wyoming-openwakeword are Apache-2.0. You pay hardware and electricity. Template users never pay c17.
How do I deploy it?
A LAN box with a mic. Open /stacks/home-assistant-voice. USB mics and mDNS do not belong on a random container.
