SPEECH Motion Speak Anywhere Technology
The Motion Speak AnywhereTM audio system combines the Knowles®
Acoustics IntelliSonicTM 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
•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
•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.
