plugin-wake-word-precise-lite's Introduction

plugin-wake-word-precise

Use Mycroft Precise tflite models as your wake word.

This module provides a Mycroft plugin module for the hotword_factory which supports the hey_mycroft.tflite model. It adds a dependency for the tensorflow lite runtime, but other than that its requirements should be satisfied by the default Mycroft environment.

Installation

This module must be pip installed into the Mycroft virtual environment before use.

mycroft-pip install https://github.com/MycroftAI/plugin-wake-word-precise-lite

Then change your Mycroft Configuration to use the installed module:

        "module": "hotword_precise_lite",
        "local_model_file": "/path/to/your/model/hey_mycroft.tflite",

The Voice Service will automatically reload when you save the configuration. Check the output at /var/log/mycroft/voice.log to ensure the plugin and model were both loaded correctly.
