Experimental Linux voice assistant for Home Assistant that uses the ESPHome protocol.

Runs on Linux aarch64 and x86_64 platforms. Tested with Python 3.13 and Python 3.11. Supports announcments, start/continue conversation, and timers.

Install system dependencies (apt-get):

• libportaudio2 or portaudio19-dev (for sounddevice)
• build-essential (for pymicro-features)
• libmpv-dev (for python-mpv)

Clone and install project:

git clone https://github.com/OHF-Voice/linux-voice-assistant.git
cd linux-voice-assistant
script/setup

Use script/run or python3 -m linux_voice_assistant

You must specify --name <NAME> with a name that will be available in Home Assistant.

See --help for more options.

Use --audio-input-device to change the microphone device. Use python3 -m sounddevice to see the available PortAudio devices.

The microphone device must support 16Khz mono audio.

Use --audio-output-device to change the speaker device. Use mpv --audio-device=help to see the available MPV devices.

Change the default wake word with --wake-model <id> where <id> is the name of a model in the wakewords directory. For example, --wake-model hey_jarvis will load wakewords/hey_jarvis.tflite by default.
