How do I add my own wake word?

The display runs microWakeWord and openWakeWord models in TensorFlow Lite format: a .tflite file. Other formats, such as .onnx, don’t work; download the .tflite version.

Find or make one

Two community libraries have hundreds of ready-made wake words, and both let you train your own:

• microWakeWord library
• openWakeWord library

Add it to Home Assistant

With the EchoLocal integration: open the EchoLocal dashboard in the sidebar, go to Wake words, and drop the .tflite file onto it. It’s offered to every display immediately, with no restart.

To add a model manually:

1. In your Home Assistant config directory, create a folder named custom_wake_words.

2. Copy the .tflite file into it.

3. Next to it, add a .json file with the same name. If the model came with one, use that. Otherwise write one like this, with the phrase you’ll say and the model’s file name:

   {
     "type": "micro",
     "wake_word": "Hey Computer",
     "model": "hey_computer.tflite"
   }

4. Restart Home Assistant. It only looks in custom_wake_words when it starts.

Use it

Pick it as an assistant’s Wake word in Home Assistant. You can also pick it on the display. See Voice assistants.
