Image Recognition
For example, a video was dropped on Wednesday called "How to hear image descriptions in Camera with Voice Over." Select Image /Descriptions and your iPhone will speak images in apps and on the web. Make sure that you have Image Descriptions turned on. When you have the camera app on, your iPhone will describe exactly what is in the viewfinder as a photo is being composed. Apple warns that voice-over recognition should not relied on in situations where you can be harmed or injured.
