I know there are two things.
- Raise to Listen
- Raise to Wake.
But I am unaware of "Raise to Speak
"Raise to Listen" and "Raise to Wake" are features on iPhones that use motion sensors to detect certain movements and perform specific actions.
"Raise to Listen" is a feature primarily associated with the Messages app. When enabled, it allows you to bring your iPhone close to your ear while receiving an audio message in the Messages app to listen to it without having to tap anything. The motion sensors detect the movement of the phone towards your ear and automatically play the audio message.
"Raise to Wake" is a feature that wakes up the iPhone's screen when you lift or raise the device. With this feature enabled, you don't have to press any buttons to check the time or see notifications. The iPhone's sensors detect the lifting motion and turn on the screen, displaying notifications, the lock screen, or the clock, depending on your settings.
Both of these features use the iPhone's accelerometer and gyroscope to detect the specific movements and trigger the associated actions without requiring manual interaction with the device.
