When I speak on my Apple watch - the text to speech is quite fast. (To me this seems like the harder Computer Science problem, and my understanding is that it is going over the wire - back to Apple - converted, and then sent back as text).
Then the subsequent action "Tell John Smith I'm on the bus" - launching an SMS with this content, seems quite slow.
This seems like the wrong way around - since I would have thought that the speech-to-text and running it over the wire was much harder to engineer.
My question is: Why is my Apple Watch Siri voice-to-text fast, but taking subsequent action is slow?
