A feature offered by Google Assistant is the ability to train it to recognize and respond only to your voice saying “Hey Google”. I’ve been using it for years and it works very well to prevent my wife and kids, and the general public, from doing anything funky by accident (or on purpose).
From reading through the documentation, it doesn’t seem like HA has this feature for its wake words. Is that correct? If so, are there plans to add it in the future?
