SPEECH 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
Client 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.
• Integrated microphones, two of the three are used at one time — The
integrated microphones help optimize the sound capturing capabilities of
the Tablet Client for speech recognition and voice recording. The loca-
tions of the microphones 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; the software determines which
two of the three provide the best results.
• 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
Using Motion Dashboard Directional Controls
The Microphone settings in the Motion Dashboard include three radio
buttons that define the directional angle that is to be used for speech
recording. The selected setting determines the angle of acceptance. The
following information is intended to help you understand the differences
between the narrow, medium, and wide angles. However, the best reference
will be your actual experience in using the technology. There are three
microphones, but only two are used at one time. If you are in landscape
mode, the microphones along the bottom edge (as viewed in primary
landscape mode) of the Tablet Client are used. If you are in portrait mode,
the two microphones along the right side are used.
• Angle of acceptance. Three pre-defined “angles of acceptance” are
part of the Motion Speak Anywhere audio technology:
• Narrow Angle (1) — Best setting for dictation, Voice over IP, “voice
noisy” environments; the microphones detect sound on a narrow
angle near the bottom center (landscape orientation) or top center
(portrait orientation) of the display. If you do not speak within the
angle of acceptance, e.g., if you turn your head while dictating or
change the angle of the Tablet Client, the sound will not be recorded.
