In many situations you're already "latent" due to interacting via voice: "Hey Siri, turn on the lights" is ~3-4 seconds to say casually, allow another 0.5-1.0 s

In many situations you're already "latent" due to interacting via voice: "Hey Siri, turn on the lights" is ~3-4 seconds to say casually, allow another 0.5-1.0 seconds due to voice processing, network, etc, and the missing 200ms is basically par for the course. Where it starts to get annoying is "door open" and "motion detected" triggers. Motion detected can be played off as a sloppiness in the sensor cone, but going from "instant" to "laggy video game" when you have a physical trigger can be relatively annoying.
