A lightweight, simple-to-use, wake word listener, including all the tools to train your own custom wake word using a recurrent neural network.
Mycroft Precise monitors an audio stream (usually a microphone) and when it recognizes a specific phrase it triggers an event. For example, by default users of the Mycroft Voice Assistant are using a Precise model trained to spot the phrase "Hey Mycroft". When Precise recognizes this phrase it puts the Mycroft Voice Assistant into command mode performing speech recognition on whatever is next said by the person using the device.
Mycroft Precise is fully open source and can be trained to recognize any short-phrase or sound, from a name to a cough.
The default "Hey Mycroft" model is included. To try it out, run:
mycroft-precise.listen /snap/mycroft-precise/current/hey-mycroft/hey-mycroft.pb
