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 microphones
help optimize the sound capturing capabilities of the Tablet PC for speech
recognition and voice recording. The locations of the microphones have been
carefully designed to detect sound input from a specific angle, rejecting sounds
from outside that angle. There are three microphones on the LE-Series; the
software and the orientation of the Tablet PC determine which two of the three
provide the best results. The LS-Series 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 canceling 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.
