The raise-and-speak feature is extremely unreliable. It seems to refuse to trigger if you’ve interacted with the watch in the last few seconds, so if you try to speak to it and it doesn’t trigger, it certainly won’t trigger when you immediately try again.

It also triggers all the time accidentally when my watch was nowhere near my mouth. I frequently look at the watch and see a message like “I don’t understand that” with a transcription of something it thinks I said.

“Hey Siri” is also unreliable, mostly because if you hesitate for a few too many milliseconds it thinks you’ve finished your query. I almost exclusively use Siri by holding the power button on my iPhone or Apple Watch.

Very interesting. Personally, I don't have any of the issues you've mentioned.

I wonder if we're somehow using it differently? Different model? Not sure what could explain the delta in our experiences.

I never use "Hey Siri" because I've always found my phone just easier to unlock and manually operate. The watch however seems to be a really great application of voice control.
