|Hardware Overiew / Integrated Noise Cancellation for B3000n badge|
The Speech Zone Fallback feature allows optimal speech recognition even if the badge is not within the speech zone.
A B3000n badge implements a speech zone during normal operations just like a B3000 badge. However, when a B3000n badge is placed at an angle or a position that renders the speech zone ineffective, the Speech Zone Fallback feature interprets the orientation of the badge and changes the operation of the microphone array.
When the orientation of the badge shifts out of the speech zone, Speech Zone Fallback moves the microphone array from a multi-microphone directional array to a single omnidirectional microphone. This change results in a wider speech zone where speech recognition is still successful.
The following figure shows the speech zones for B3000 followed by the speech zone available when Speech Zone Fallback is activated in B3000n badge.
