The open source, privacy-focused voice assistant, built to work with Home Assistant

Home Assistant Voice Preview Edition is the open source, privacy-focused voice assistant built to seamlessly connect with Home Assistant, and preview the future of voice today. Its advanced audio processor and dual microphones allow it to hear your commands and control devices. Tactile controls, the injection-molded case and LED ring lend to its premium feel, allowing it to blend into the home. 

Note: Voice Preview Edition requires Home Assistant to operate. Lower-performance Home Assistant hardware may result in slower speech processing. For optimal performance, we recommend offloading speech processing to Home Assistant Cloud if your hardware is less powerful. If you are experiencing issues please try to upgrade to the latest firmware by connecting your HA Voice PE to a computer via USB-C and using this tool "https://esphome.github.io/home-assistant-voice-pe/".

Requirements

Home Assistant already configured on another device. 

For fully local speech processing, we recommend a 
Home Assistant system based on an Intel N100 or higher
for the best experience. Lower-performance hardwaremay
work but could lead to slower processing.
If you experience delays, you have options:

  • Consider using external hardware for voice
    processing, such as a
    more powerful server or a dedicated system.
  • Offload speech processing to Home Assistant Cloud,
    which ensures smooth performance regardless of
    your hardware.

This flexibility allows you to choose the setup
that works best for your needs.

Language support

for an
up-to-date list.

Excellent service and friendly

I paid for the device and within 12 hours received the shipping information. I received the product and then there was a physical receipt with a handwritten note that said "Thank you". These small touches and little details make a difference in showing the humanity of those who are involved with the creation and distribution of innovative technology. Thank you for providing excellent service

Could be improved

I was excited to move away from Alexa and Google, even though I knew I’d miss the smart assistant functionality. When I saw the Home Assistant Voice Preview Edition (V PE), I decided to give it a try.

Installation was straightforward, but keep in mind that you’ll need either a powerful local machine to run the LLM (Large Language Model), a separate LLM server, or a subscription to Home Assistant Cloud. It’s not as plug-and-play as Alexa or Google—but I was okay with that.

That said, the V PE has a few drawbacks. The microphone isn’t very sensitive. For example, if I’m in the kitchen and ask for a timer, I have to walk back to the living room where the V PE is located—it won’t pick up my voice from another room. The built-in speaker also leaves something to be desired; some responses are mumbled or get cut off mid-sentence.

You'll also need to spend some time tweaking settings. By default, it reads web responses out loud—including entire pages with buttons, URLs, and other irrelevant content. When I asked for the hours of the local USPS, it read the entire website aloud.

Bottom line: the V PE is promising but definitely not plug-and-play. It takes work and has a learning curve—especially for anyone used to the simplicity of mainstream assistants.

I ended up installing LLM onto a separate computer and paid for openAI API. I might switch over to HA Cloud for the monthly fee. I feel the fee is worth it as I will be supporting the Devs.

Once I can get it to play music, it'll replace my Google speakers

It works pretty well, but I can't replace my Google speakers with these until they can be used to play music via Music Assistant.

But otherwise, these are great when an LLM is used as failover.
