WWDC 2026 delivered genuine back-and-forth conversation, a new expressive customizable voice, and far better system-wide dictation.
How natural, fast, and trustworthy is the back-and-forth? Voice quality, latency, interruption handling, multimodality, and the sense that the assistant understood you the first time.

Siri, rebuilt: conversational and “profoundly more capable”
“Siri is now a profoundly more capable assistant, more conversational, so you can go back and forth like never before and get detailed, engaging answers.”
The personal-context Siri Apple promised back in 2024 finally ships in iOS 27, with a new, customizable expressive voice and a major jump in system-wide dictation accuracy. It is the most consequential Siri change in a decade, though the real-world quality only proves out as iOS 27 reaches devices this fall, so we move the grades with a verification caveat rather than to the top of the field.
