Note that speech to text and voice assistant functionality happens on device on Android since 2019 for privacy (https://blog.google/products/assistant/next-generation-google-assistant-io/ https://blog.google/products/assistant/next-generation-googl...), while iOS continued to send data to Apple until 2021 (https://www.theverge.com/2021/6/7/22522993/apple-siri-on-device-speech-recognition-no-internet-wwdc https://www.theverge.com/2021/6/7/22522993/apple-siri-on-dev...). Neither privacy nor UI were an issue. Android used the on-device speech to text to transcribe phone calls, so I never have to listen to menu options repeat (though it doesn't yet automatically enter my SSN or account number), automatically caption arbitrary audio playing on the device, etc. These are other features I use frequently that Apple will get to eventually, but it's not because of privacy or UI.
