OS X Mountain Lion: Hear your computer speak text
If you have trouble reading text on your computer screen, you can have your computer speak text that’s on the screen when you press a key or set of keys.
You can also use VoiceOver, the spoken interface for OS X, to hear descriptions of every item on the screen and to control your computer using the keyboard.
For more information about the options in Text to Speech preferences, click the Help button in the bottom-right corner of the Text to Speech preferences pane.
- Choose Apple menu > System Preferences, click Dictation & Speech, and then click “Text to Speech.”
- Select the “Speak selected text when the key is pressed” checkbox.
By default, speaking is enabled when you press Option-Esc. To choose a different key, click Change Key, press one or more modifier keys (Command, Shift, Option, or Control) together with another key, and then click OK.
Use the key
To have the computer start speaking, press the specified key. To stop the speaking, press the key again.
If text is selected when you press the key, the selected text is spoken. Otherwise, available text items in the current window are spoken; for example, if Mail is the current window, a message is read. If no text items are available, you hear a beep sound effect.
