I'd be (pleasantly) surprised; look at how long it takes them to allow system apps to get replaced with downloadable 3rd party.

And even then, the activation keyword is likely to be whatever Apple says. Similar logic as 3rd party keyboards, don't want user input to get stuck on even merely potentially untrustworthy or buggy code.

Correct me if I’m wrong but isn’t the activation word “special” in that it has to work in very low power states? I always assumed that is why the wake words are fixed, because said words need to “fit” within a very small power budget.

Could be — I've heard rumours along those lines, but none came with evidence.

The rumors were true.

Thanks :)

That's not due to incompetence; that's due to not seeing any reason to do it.

I was not intending to imply otherwise.

It's been in an 'AI' rewrite for a while now. Pretty sure we'll see something next year.

It's been rewritten several times, people largely don't notice because they don't try using it in different languages. And of course because they want to seem savvy so they repeat impressions from other people's posts, not realizing those posts are years old.
