Linux Voice Assistant

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.

See the tutorial to build a satellite using a Raspberry Pi Zero 2 W and a ReSpeaker 2Mic HAT.

What's working:

• This fork introduces the ability to use Wyoming OpenWakeWord (OWW) instead of MicroWakeWord (MWW).
• Now supports both ALSA and PulseAudio playback backends using the updated linux_voice_assistant/mpv_player.py.
• You can choose between ALSA and PulseAudio with either MWW or OWW simply by enabling the matching systemd service file.
• You can change the OWW wake word within HA after the VLA is registered. (defaults to the wake word defind in the systemd config file)

Installation

Install system dependencies (apt-get):

• libportaudio2 (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
