Google assistant with offline wake word

Hi everyone!

Hope you are having a great day!

My challenge is the following:
I would like to have google assistant control all my smart devices, and have a physical speaker in my home I can talk to, ask to turn off the lights etc.

The catch is that I would like this to have an offline wake word detection. My goal is to have google assistant but without it listening to every single coversation and sending those conversationts to the cloud to analyze my speech in search for a wakeword.

Has anyone done this? Or is this even feasible?

Thanks for your help in advance!


Google Assistant is not sending data all over the time to find the hotword. Hotword detection is made offline.
