Motion Speak Anywhere Technology
The Motion Speak Anywhere
TM
audio system combines the Knowles
®
Acoustics IntelliSonic
TM
software application with integrated microphones to
let you record audio, dictate notes, and use voice commands without the
need for a microphone headset. These capabilities make the Motion Tablet
PC with Speak Anywhere technology a valuable tool for mobile users in a
variety of work settings, including small or large groups, or for individual
dictation or voice commands.
• Two integrated microphones are used at one time.The integrated micro-
phones help optimize the sound capturing capabilities of the Tablet PC
for speech recognition and voice recording. The locations of the micro-
phones have been carefully designed to let the system detect sound
input from a specific angle, rejecting sounds from outside that angle.
There are three microphones on the LE1600; the software and the orien-
tation of the Tablet PC determine which two of the three provide the best
results. The LS800 has two microphones which are used at the same
time.
• Knowles Acoustics IntelliSonic software — This software lets you direct
sounds coming from a specific direction to the microphones, while can-
celing interfering noise from other directions, thus minimizing the effects
of environmental noise and eliminating acoustic echo feedback. It is
based on the following audio technologies:
• Array Processing or “beam forming” software — Removes all sound
outside a software-defined “angle of acceptance”
• Noise Suppression — Removes background and ambient noise
• Acoustic Echo Cancellation (AEC) — Removes echo caused by the
microphone picking up the system’s speaker output, thus preventing
feedback
Speech Recognition
Speech recognition lets you convert spoken words into typed text or into
voice commands, you can use speech to correct errors, format text, or
control programs. This is sometimes quicker than typing or writing text.
Before you can use speech recognition, you must first train the system for
your voice, pronunciation, speaking pace, and inflection. These adjustments
are made through the Speech utility on the TIP window. Speech recognition,
including dictation and voice commands is available through the TIP
window. Tap the Tools and Options icon in the TIP. If this is the first time
you have activated Speech, you will be asked to complete the Voice Training
application. The more training you do, the better the speech recognition will
be.
