Home Assistant add-on that uses openWakeWord (demo on huggingface) for wake word detection over the wyoming protocol on NVIDIA Jetson devices. Thank you to @ms1design for contributing these Home Assistant & Wyoming containers!

Features

• Works well with home-assistant-core container on Jetson devices as well as Home Assistant hosted on different hosts
• Use custom wake word's, pass model name as OPENWAKEWORD_PRELOAD_MODEL to preload custom model. For example you can find jetson (jets_un) wake word model included in /share/openwakeword models directory.
• Supports *.tflite CPU wake word models
• Supports *.onnx CUDA wake word models [WIP]

Requires Home Assistant 2023.9 or later.

docker-compose example

If you want to use docker compose to run Home Assistant Core Voice Assistant Pipeline on a Jetson device with cuda enabled, you can find a full example docker-compose.yaml here.

Environment variables

Variable	Type	Default	Description
OPENWAKEWORD_PORT	str	10400	Port number to use on host
OPENWAKEWORD_THRESHOLD	float	0.5	Wake word model threshold (0.0-1.0), where higher means fewer activations.
OPENWAKEWORD_TRIGGER_LEVEL	int	1	Number of activations before a detection is registered. A higher trigger level means fewer detections.
OPENWAKEWORD_PRELOAD_MODEL	str	ok_nabu	Name or path of wake word model to pre-load. The name of the model should match with name used during custom wake word model training. When changing this, it's also recommended to set WAKEWORD_NAME variable with same value for wyoming-assist-microphone container
OPENWAKEWORD_CUSTOM_MODEL_DIR	str	/share/openwakeword	Path to directory containing custom wake word models. Skip the trailing slash (/)
OPENWAKEWORD_DEBUG	bool	true	Log DEBUG messages

Configuration

Read more how to configure wyoming-openwakeword in the official documentation:

Training custom wake word's

Note

You can find a custom trained, example jetson (jets_un) wake word model in the custom models directory (/share/openwakeword). To use it, set WAKEWORD_NAME to jets_un in appropriate containers.

The Home Assistant Community has trained numerous wake word models, as detailed in this GitHub repository. However, these models are specifically designed for use with CPU.

To train a new wake word model for CPU (*.tflite) or cuda (*.onnx), you can follow @dscripka documentation or just jump to the point and use wake word training environment.

TODO's

• Build openWakeWord from source based on onnxruntime gpu enabled container (currently openWakeWord is still using tflite models instead onnx)
• Custom Wake Word Models training container using automatic synthetic data creation
