1 Narrow Angle; 2 Medium Angle; 3 Wide Angle; 4 Microphones (only two of
the three microphones are shown in this illustration of the LE1600 Tablet
PC).
Skew angle. The pre-set sound detection area is straight in front of
the system display. If you want the system to receive sound from
elsewhere, you can skew the receiving direction towards one or the
other microphone (keeping the same relative angle of acceptance.
Setting up the skew angle for calibration:
1. Open the Motion Dashboard.
2. Under Microphone, tap Narrow Angle or Medium Angle. (You can-
not calibrate wide angle.)
3. Move to where you want the microphone to detect your voice.
4. Tap Calibrate. A block of text appears.
5. Read the text aloud, speaking normally towards the Tablet PC micro-
phones. This should take 20-40 seconds.
NOTE: In many cases, you will not need to calibrate the
microphone because the audio system filters out many
unwanted sounds. If you are dictating in an office or recording
during a meeting, the audio system may work well with no
additional calibration.
IMPORTANT: The audio system does not store calibrations. If
you change to another angle/position and then return to the
previous one, you must re-calibrate the audio system.
Enabling Speech Recognition Enrollment. It is necessary to train the
system to your voice before you can use the Speech Dictation and Voice
Command capabilities of the Tablet PC. The procedure is used to adjust the
microphones and train the Tablet PC for the characteristics of your voice.
The entire process takes about 10 minutes. It is advisable to move to a quiet
environment before starting this procedure.
