Siri Customization: Pace & Expressivity in iOS 27 Beta 3

Apple has enabled new voice customization features for Siri in the latest developer beta of iOS 27. With beta 3, testers can now adjust how quickly Siri speaks and how much human-like emotion it conveys. These controls were previously labeled "Coming soon." Now, users can find two sliders in the Siri settings panel: one for "Pace" and another for "Expressivity." You can slow down or speed up Siri's speech rate and adjust its emotional inflection. As you make changes, Siri plays a sample phrase so you can hear the effect in real time. What's interesting is that these controls build on a broader voice selection overhaul Apple first previewed in June. Users can now pick from a range of regional accents and fine-tune delivery. Apple says the goal is to make Siri feel more natural and personal as the company rebuilds the assistant around generative AI. The bottom line is that this move follows a trend among AI voice assistants toward greater personalization, making the interaction more natural for you.
