Tips
For best results:
•
Use a close-talk microphone that rests near the side of your mouth instead of
a desktop or built-in microphone.
•
Train the speech recognition engine in the same environment in which you
will use it. For example, if you use the engine mostly in the car, perform
training in the car. Perform three training sessions to get the best results.
•
When training, speak the same voice as you will when giving voice commands
to the computer. Speak distinctly and at an average speed, as if giving a
command.
•
Use the Microphone Wizard to ensure your microphone is working correctly
and to view tips on microphone selection and placement. To use the wizard,
click Microphone Setup on the Voice tab of the Options dialog. Or, from the
Start menu on your computer, browse to the Control Panel and double-click
the Speech icon to open the Speech Properties dialog box.
•
To increase the likelihood of correct speech recognition, on the Voice Settings
tab in the Options dialog box, select the Commands start with check box
and then type the appropriate word/phrase in the text box (if using a single
word, use a word with more than one syllable). For example, if you type
computer, you would then say "Computer, zoom in."
Speech Recognition Tips
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
