How to adjust general iPhone and iPad settings Scroll down to the Allow Access When Locked section and Tap Siri to turn off the ability to use Siri when your iPhone is locked. Tap on Touch ID & Passcode or Face ID & Passcode, depending on your iPhone or iPad model. If you are security conscious and have activated a Passcode Lock for your iPhone or iPad, you may want to make sure Siri isn't allowed to bypass that lock - it's less convenient, but that's always the cost of security. Since Siri is usually activated by just holding down the Home button, it can pose a security risk to the data on your iPhone or iPad. If you want to do things like have Siri call your mother or significant other, you'll have to make sure that you create relationships for your contacts first. If you want it to use you, you'll need to create a contact for yourself. Tap the contact whose information you'd like Siri to use. Siri securely looks at information from your contact card to perform specific actions, like "Give me directions to home," or "call my mother." If you've switched cards or want Siri to pay attention to other data, you can change that from Siri's settings. Siri will now answer your revised question or command. Tap on the text of your question or command at the bottom of the screen.
If you turn on the Always Show Speech option from the Siri responses, then you'll be able to get complete transcriptions of your question or command for Siri, allowing you to edit them. Tap the toggle if you want to Always Show Speech transcriptions.
The voice will then download if you don't have it on your iPhone or iPad already.
