Changing Voice Output

calculated.
Your application offers text-to-speech technology so you can receive spoken updates about
your route directions, next turn, next stop, current location, time to finish, or current
coordinates when navigating with a GPS receiver. Text-to-speech allows hands-free
navigation of the program on your computer.
Use your text-to-speech engine to change and preview the tone and quality of the
computer's voice.
