What changed for Siri

  • The iOS 27 developer beta adds a setting for Siri's speaking rate
  • Users can also adjust the expressiveness (intonation) of the assistant's voice
  • The change was spotted in a test build that is currently available only to developers

Why it matters for voice assistants

For several years, Apple has been gradually moving Siri onto generative AI technology, promising more natural, personalized speech and a better grasp of conversational context. Rivals are betting on the same idea: Google with its Gemini-based voice assistant and Amazon with Alexa+ both want voice interfaces to sound livelier and more flexible, not like a set of prerecorded phrases. Fine-grained control over speaking rate and expressiveness is a small but telling step in that direction, giving users more say over how the assistant sounds instead of a single default voice.

What it means

At first glance, Siri's speech rate and expressiveness settings look like a routine update. But they fit Apple's broader trajectory: steadily making its voice assistant more natural and customizable as more advanced AI models are built into it.
