iOS 27 beta 3 enables two new Siri voice customization controls — Pace and Expressivity — that were previously marked 'Coming soon' in earlier betas. Users can now use sliders to adjust how quickly Siri speaks and how much human-like emotion its voice conveys, while also choosing from voices with different accents. The feature is part of Apple's broader effort to rebuild Siri around generative AI. The update also compares Siri's options to ChatGPT's more extensive voice customization, which includes warmth, enthusiasm, and tone style controls rolled out in December 2025.
