Use Point and Speak to Let Your iPhone Detect Objects
Besides Text Detection, Apple also added a Point and Speak feature to the Magnifier app.
This feature, as you can guess by its name, will let you point to an object and let your iPhone’s camera detect what it is and give you a description. Just like Text Detection, you’ll need an iPhone 12 Pro or a later Pro model to use this feature.
Open the Magnifier app on your iPhone and then tap on the Detection Mode option. Select Point and Speak — the icon with a hand pointing to some lines — and then point at the object or text you want.
