Type to Siri is a function designed for those who are unable to speak, but it can be enabled by anyone who would like to try typing to Siri instead of speaking to Siri.
Enabling Type to Siri
- Open the Settings app.
- Choose "General."
- Select the "Accessibility" section.
- Scroll down and "Siri."
- Toggle on "Type to Siri."
When you have Type to Siri turned on, it's an all or nothing setting. All commands must be typed if you access Siri through the Home button or Side button. If you say "Hey Siri," though, Siri will respond to spoken questions as normal, so you can use spoken commands alongside typed commands in this way. Siri will also respond to voice commands when the AirPods are connected and the personal assistant is activated, either via a tap on the AirPods or by saying "Hey Siri" handsfree on AirPods 2.
