Apple’s iOS 27 beta 3 introduces new customization options for Siri’s voice. Multiple outlets report that the update enables separate controls labeled “Pace” and “Expressivity,” allowing users to adjust how Siri delivers spoken answers. The “Pace” control changes how quickly Siri narrates responses, while the “Expressivity” control lets users modify the tone or expressiveness of Siri’s speech. Reports also indicate that these settings can influence how Siri sounds across more than one Apple app experience, including within Maps and Safari. Several sources note that the availability of these options was previously expected or described as “coming soon,” and the rollout is tied to the iOS 27 beta 3 release. Tech outlets describe the changes as part of a broader effort to let users fine-tune the assistant’s conversational delivery rather than only using standard voice and language selections. While the reports vary slightly in wording, all agree that iOS 27 beta 3 adds the new Siri voice sliders and that they affect Siri’s speaking rate and expressiveness.
