See [the tutorial](docs/linux-voice-assistant-2mic-install.md) to build a satellite using a [Raspberry Pi Zero 2 W](https://www.raspberrypi.com/products/raspberry-pi-zero-2-w/) and a [ReSpeaker 2Mic HAT](https://wiki.keyestudio.com/Ks0314_keyestudio_ReSpeaker_2-Mic_Pi_HAT_V1.0).
This fork introduces the ability to use Wyoming OpenWakeWord instead of MicroWakeWord.
### 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)

You shouldn't have to change anything if you are using the driver provided in this repo. If you are using something else, find your sound device names and update the linux-voice-assistant/service/linux-voice-assistant.service file to match sound card details:

## 9. Verification
- Expect logs like `Connected to Home Assistant`
- Look for `[OWW] Detection: name=...` followed by re-arming/cycling
- Ask: *“What time is it?”* and confirm TTS reply
- Use journalctl -fu linux-voice-assistant.service to check for errors. Debugging is enabled.

## 10. Change OWW detection model (Depricated-Wake word can be selected in HA now)
## 10. Change OWW detection model
After the LVA is registered with HA, you can change the Wake Word model used in the ESPHome Voice Assistant entity.
Edit the linux-voice-assistant.service file and change the OWW configuration argument for --wake-word-name.
Project OWW models include:
```text
alexa_v0.1.tflite
hey_jarvis_v0.1.tflite
hey_mycroft_v0.1.tflite
hey_rhasspy_v0.1.tflite
ok_nabu_v0.1.tflite
alexa_v0.1.tflite -> Alexa
hey_jarvis_v0.1.tflite -> Hey Jarvis
hey_mycroft_v0.1.tflite -> Hey Mycroft
hey_rhasspy_v0.1.tflite -> Hey Rhasspy
ok_nabu_v0.1.tflite -> OK Nabo **(not working for me right now)**
```
Additional community provided OWW models available from this repository:
https://github.com/fwartner/home-assistant-wakewords-collection
You just copy the ones you want into the ~/wyoming-openwakeword/wyoming-openwakeword/models directory. If a model is currupted, the wyoming-openwakeword.service will fail to start.
**Word of warning. I have had problems with some of the community provided wake words. YMMV**
Edit linux-voice-assistant.service file:
```bash
sudo systemctl edit --force --full linux-voice-assistant.service
```
