Last night while driving, I used "hey Siri" to send a message to my wife describing my burrito order. I said "I'd like a chile verde carnitas super burrito". Siri got the entire message correct the first time (and the dictation was nearly instant). Never before was I able to mix Spanish and English in a sentence like that. I was impressed! In general, Siri in iOS 10 (and Watch OS 3) is much improved. I'm noticing faster performance, more accurate dictation, and more flexible understanding of my phrases. It's not perfect - my wife reports it gets tripped up when she asks Siri to text me, but I think that is a specific quirk that needs an update to sort out. Has anyone else noticed improvements like this?
