Topo USA User Guide
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).
Your best speech recognition responses will always be to use a close-talk
•
microphone with voice output using the laptop speakers rather than a
headphone speaker so that the computer will not "hear itself."
If you are speaking with someone else in the room, have a radio or television
•
on, and so on, the computer may think those sounds are commands to follow.
