Using Voice Navigation

Voice Overview

To use voice navigation, you must have a

2-D or 3-D GPS fix

and a route

calculated.


Using the speech recognition and text-to-speech technology included in your application,

you can issue a series of voice commands to a laptop computer. The voice commands

activate basic navigation, map control, and GPS features, providing you with hands-free

program navigation so you can concentrate on your driving. When tracking with a GPS

receiver, you can receive spoken updates about your route directions, next turn, next stop,

current location, etc.

Notes

• The Voice label on the Voice tab displays red when the microphone is activated.
• Your application comes equipped with Microsoft® English Recognizer Version 5.1.

You can also use other speech recognition engines that you may have purchased

separately from other software companies. Such speech recognition engines must

support SAPI 5.1 to be available to you in your application. See the Speech

settings in the Windows Control Panel for more information about your engine.

• If you have purchased other voices (text-to-speech engines) that are SAPI 5.1-

compatible, they are available in your application.

• You must have a microphone attached to your computer to use speech

recognition (for input).

• For tips on using the speech recognition feature and setting up your microphone,

see

Speech Recognition Tips

.

• If you are having difficulty hearing the voice output, adjust the volume on your

external speakers or adjust your computer's volume using the settings in the

Windows® Control Panel.

• If you chose the custom installation option when you installed your application,

you were asked whether or not to install a speech recognition engine for voice

input. If you want to use voice input and selected not to install a speech

recognition engine when you installed the program, you must uninstall and then

reinstall the application, making sure to select to install the speech recognition

engine.

• The speech recognition engine is automatically installed on Windows Vista

and Windows 7 operating systems.

• If you have another DeLorme product installed and already opted to install

the speech recognition engine, you may not see the option to install it

again.
