I've had reliability problems with my toddler as well, and I suspect it's the treble voices. My primary device (for him) is an LG TV, though, which is push-to-talk. As long as he holds the mic up to his mouth properly it'll usually get what he's saying. (It probably also helps that he's speaking American English).

I don't think my Nest Hub Max or Google Home Mini has ever caught the "Hey Google" when he says it, but it doesn't really matter for our use-cases with him.

I wonder if it's by design? If I was building a home assistant product, one of the cases I'd build defensively against would be kids saying "hey google delete all emails"...

Maybe I'm out of the loop, but when Alexa/Google/Siri started coming out in home-accessible versions, I did think there was a beat missing in terms of recognising a voice-print (if such a thing is possible) or similarly requiring some form of authentication.
