>If you're adding an artificial delay after "Hey Siri", waiting for her to respond before continuing, then you're just making it harder. Just speak conversationally.

I actually find this frustrating and I'm surprised Apple went this way given their usual commitment to humanistic interaction design. When I'm addressing someone in real life, I call out their names and wait for acknowledgement that they're listening before rattling off questions at them.

The fact that Siri doesn't acknowledge it's listening or even give you a visual indicator that it's attention has been caught (like a person does by making eye contact) makes interaction with it feel strange and unnatural.

It's especially weird when you're in a room with multiple "Hey Siri" capable devices. If I call out "Hey Siri" I'd like to know whether I should be speaking at my iPhone, my iPad, my girlfriends iPhone, or a hypothetical HomePod. Which ones should I direct my voice at and expect a response from? All? None? Some? Can I tell my girlfriend's iPhone to go away because I'm talking to my phone right now? I'd like to. . .

Yes it does. It makes a very distinct sound when it starts listening, and the screen itself transitions to the Siri screen and shows the animating waveform.

It's weird. It takes several seconds after saying "Hey Siri" before it starts doing that. It works fine if you say "Hey Siri blah blah blah." But if you wait for the indication, then it actually messes up. It's listening before it's brought up, but it doesn't seem to listen to what you say immediately after it's brought up, it takes a second. It's very strange.

And it doesn't start listening until about a second later.

Which is a big problem.
