Same with android phones - a super-specific hardcoded phrase is much easier to work in the power budgets required for an "always on" part of the device.

It's why a manufacturer (like Samsung) can change that sort of thing on their devices, but it's not realistically something an end user (or even an app) can customize in software. It's not some "arbitrary" limitation.

Back in 1992 or so the NeXT could distinguish (was it 16 or) 64 fixed, trained, phrases. Point being, it doesn’t take too much compute with a finite vocabulary.

But wouldn't adding your own phrases require a reflash of parts of firmware in this context?
