What’s new in VoiceOver
VoiceOver in macOS High Sierra offers new features to give you greater control while using a Mac.
Note: VO represents the VoiceOver modifier.
Enhanced multilingual support. If VoiceOver detects that a language has been associated with text that it’s reading, it automatically switches to another voice and reads the text in that language. You can choose and customize the voice that VoiceOver uses for a specific language in VoiceOver Utility. For example, if you add the French language and customize a voice for it, VoiceOver will use that French voice to read any text that has been tagged as French for screen readers.
Image descriptions. Press VO-Shift-L to have VoiceOver describe text that appears in an image, even if the image isn’t annotated. VoiceOver can also tell you whether a photo contains a tree, a dog, or four faces with smile
