Summary
The update is part of Apple’s broader effort to make Siri feel more natural and personal, as it rebuilds the assistant around generative AI. However, ChatGPT’s voice-customization options allow users to go even further, as the ability to adjust the AI’s warmth and enthusiasm was rolled out in December 2025, alongside options to configure the base style and tone. First introduced at Apple’s Worldwide Developers Conference (WWDC 26) in June, Siri’s voice controls let users personalize their Siri experience beyond choosing a male- or female-sounding assistant. As you make the adjustments, Siri will practice saying some common things, like “You have one new message,” so you can get a sense of how the different voices sound.
