Using Voice Navigation and Speech Recognition

Training the Speech Recognition Engine
To use voice navigation, you must have a
2-D or 3-D GPS fix
and a route
calculated.
You should train the speech recognition engine to provide good speech recognition results.
Before training, ensure your microphone is active and the speech recognition feature is on.
For more information, see
Activating and Monitoring Speech Recognition
.
To Train the Engine to Recognize Your Speech Patterns
You should train the speech recognition engine to recognize your specific speech patterns.
This is often done by reading a predetermined piece of text supplied by the creator of the
speech recognition engine. If the engine supports multiple user models, you can train the
engine to recognize more than one speech pattern.
Use the following steps to train the speech recognition engine to recognize your speech
patterns.
1.
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.
2.
Click the Voice Settings tab.
3.
Select the microphone you intend to use from the Microphone drop-down list.
4.
Select your preferred user voice model from the User Profile drop-down list.
Note To create a new speech recognition profile for each of your working
environments (noisy, quiet) and users (your spouse, your child), click Speech in the
Windows Control Panel.
5.
Select your preferred speech recognition engine from the Recognizer drop-down
list.
Note Select the most recent version available in the drop-down list.
6.
Click Speech Profile Training to display the speech training wizard specific to your
speech recognition engine.
Note This feature is available only if it is supported by your speech recognition
engine.

Follow the on-screen instructions.
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
