Apple will soon allow European iPhone customers to choose third-party voice assistants like Google Assistant, Gemini, ChatGPT, and others instead of Siri.
The change is in response to the EU's Digital Markets Act, mandating fair competition and the ability to override built-in defaults.
A new 'Default Assistant' setting will be included in iOS 18.5 and iOS 19 for EU devices, enabling users to select system-level assistants.
While third-party assistants will handle core intents, Siri's infrastructure will still be deeply integrated into iOS, impacting user-initiated voice-app launches more than behind-the-scenes integrations.
