What is VoiceOver
VoiceOver is the free, built-in screen reader available on all Apple computers running Mac OS X Tiger or later. Unlike traditional screen readers for Windows, VoiceOver is part of the operating system itself and not a “bolt on” software package installed after the fact. VoiceOver provides speech, output and screen magnification for the blind or low vision user, and refreshable Braille displays can be connected and used as well. The user has full keyboard control over their Mac, and can utilize their computer without any assistance . VoiceOver is easily customizable by the user, and one has access to many features and functions that can be turned on or off, such as sound alerts and verbosity settings.
Daily tasks such as email, word processing, web browsing, chatting and listening to music can all be performed on the Mac with applications included on every Macintosh computer; Apple Mail, Text Edit, Safari, iChat and iTunes respectively. All of these programs work with VoiceOver with the same level of accessibility as on a Windows computer. Additionally, there are several third party applications accessible out of the box that a user can purchase or download for free.
