This program utilizes the built-in speech synthesis capabilities of your computer, if available. To change the voice used for the speech synthesis, use the Speech Control Panel. (The Control Panels, including Speech, can usually be found in the Apple Menu.) Hang2000 can utilize the speech synthesizer to spell the guessed word (or phrase), to speak the guessed word (or phrase), and to speak words of encouragement (or discouragement!) at the end of each game. You can customize how the speech synthesizer is utilized in the Preferences Dialog.
