To use voice navigation, you must have a 2-D or 3-D GPS fix and a route 
calculated. 

 
The following tips provide information on using the speech recognition feature and 
setting up your microphone. 

•  Speech recognition is only active when your application is the active window. 
•  Commands become enabled based on your current GPS status, your data 

zoom level, and other factors. Enabled commands do not have a red "x" on 
the icon. 

•  Disabled commands have a red "x" on the icon. 

Note  Some commands are disabled if a route is not calculated or if the GPS 
has not been initialized. 

•  Avoid noisy environments when using voice command navigation. 
•  Use a close-talk microphone for best speech recognition results. 
•  Properly position your microphone to achieve the best speech recognition 

results. For a close-talk microphone, the recommended position is a thumb-

width from the corner of your mouth and slightly to the side. For more 
information, see the note at the end of this topic. 

•  When issuing commands to the computer, use the same tone that was used 

when during the speech recognition engine training. 

•  Keep the microphone as far as possible from the car radio or console, 

computer speakers, or other speakers. 

•  If your microphone is near your speakers, and you are using the microphone 

together with voice reminders (GPS VoiceNav), the program may recognize 
some of the words that it is speaking and react to them. Here are ways to 

eliminate this problem: 

•  Make sure that you have chosen the Voice Output device (speakers, 

headset) and the Input device (on-board microphone, headset 

microphone) that you intend to use with DeLorme GPS voice 
navigation. Use the selections that are available in the Voice settings 

tab in the Options dialog box. 

•  If more than one speech recognizer is available in the drop-down list, 

choose the most recent (highest version number).
