Letting Mac Do the Talking
Your Macintosh can speak to you as well as listen. OS X can read aloud what appears on your screen, such as typed text, alert messages, window items, menus, and other interface items. It speaks using a synthesized voice, such as Pipe Organ, Cellos, or Junior. Some voices, such as Pipe Organ, are based on a song and sing the voice. Alex is a new synthesized English voice that uses advanced Apple synthesis to deliver a more natural speaking voice at a faster rate. You can use the Dictation & Speech pane in System Preferences to select a default voice, set talking alert options for when alerts appear on the screen, and other spoken options for the user interface. Instead of just showing you, the Mac can tell you when an application needs your attention, such as when your printer is out of paper, or read buttons, icons, tabs, dialog options, and selected text in e-mails and documents when you point to it as well as read select text when you press a keyboard shortcut.
