Why not use an easier to detect wake “word”, like two claps in quick succession? Or a couple of notes of a melody?

[hamdingers]

Can't clap if your hands are full and I would not subject my family to my attempts at delivering a melody.

I haven't tried training my own wake word though, I'm tempted to see if it improves things.

Personally I'd pick "Cthulhu"

What about whistling?
