Siri says Uhuh

Speak your question directly; without pause. “Hey Siri please play the playlist chill, shuffled.” Or whatever.

With recent devices, the Siri processing is local; on device. You’re not waiting for a network connection to some remote Apple server to be established and receive and process your request: https://www.theverge.com/2021/6/7/22523438/apple-iphone-siri-on-device-processing-ios-15-wwdc-privacy

Or as I prefer to think about all of this, best being polite to Siri (Please and thanks) and not wasting Siri’s time before providing the requested task; of getting right to the request. This directness completely bypasses Siri telling me to get going with my request; with “uh-huh”, too.

I too find the dictionary-defined word “uh-huh” (dating from 1858) a fine response, too. I envision tapping fingers.

I personally find "Uhuh" very fascinating. rather I love the way Siri says that.
