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.
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.

Follow the on-screen instructions.
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 voice 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. Performing
three training sessions provides 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.
•

word/phrase in the available text box. For example, if you type
computer
, you would then
