Voice Preferences
To use voice navigation, you must have a 2-D or 3-D GPS fix and a route
calculated.
The Voice tab in the Options dialog displays a series of Engine Option buttons. These
option buttons allow you to view information or change preference settings in your
speech recognition or text-to-speech engines. Some speech recognition or text-to-
speech engines do not support some of the preference options.
To View and Update Speech Recognition Preferences
To change speech input preferences, click the Options button on the
toolbar (or click the arrow next to the Options toolbar button to open the menu;
then, click Options to open the dialog box), and then click the Voice Settings tab.
The following options are available under the Speech Recognition area of the dialog
box.
• Microphone Setup–Opens the Microphone Wizard to adjust speech
recognition whenever you change microphone or noise environments.
• Speech Profile Training–Opens Voice Training Wizard to train the engine to
recognize your speech patterns. This process may take 10–15 minutes to
complete.
• DeLorme Training–Opens an abbreviated version of the Voice Training
Wizard. This dialog trains the system on DeLorme voice commands.
• Add/Delete Words–Opens the Add/Delete Words Wizard with the
pronunciation wizard specific to your speech recognition engine. You can
enter, edit, or view the words in your pronunciation vocabulary. Use this
wizard when the speech recognition has trouble understanding a specific word
that you are saying.
