Acoustic Magic's Voice Tracker Microphone Certified by GeckoSystems for Voice Control of Mobil Robot

GeckoSystems has certified the Voice Tracker™ Array Microphone for voice control application on board its CareBot™ Mobile Service Robots because the Voice Tracker™ has an effective range of 15+ feet and scans a full 180 degree field of view.

CONYERS, GA -March 5, 2004; GeckoSystems Inc., a leading developer of mobile robot solutions has Certified the Voice Tracker™ Array Microphone for use with its CareBot™ Mobile Service Robots (MSRs).

According to Martin Spencer, CEO of GeckoSystems, the combination of the Voice Tracker™ Array's long effective range and the robustness of the GeckoChat™ verbal interaction package enables not only verbal command and control but also surrogate short -term memory assistance such as a verbal reminder for timely medication regimens and other appointments. As part of the Certification process, GeckoSystems tested the Voice Tracker™ Array at ranges of up to fifteen feet in environments with low noise and up to six feet in environments with high noise, while the MSR automatically self -navigated. GeckoSystems is completing the final stages for delivering an MSR platform to home healthcare (telemedicine) markets.

"We believe that our Voice Tracker™ intelligent array microphone is useful for robotics command and control because it scans a full 180 degree field of view in front of the robot, and can even pickup speech from behind," said Bob Feingold, CEO of Acoustic Magic.

The Voice Tracker locates a talker and electronically steers a "listening beam," like an acoustic searchlight, in that direction. This creates spatial filtering; sounds from other parts of the room are not picked up. In addition, constant background noise is removed by digital noise reduction algorithms. This two -stage noise reduction, coupled with increased sensitivity since the Voice Tracker's eight microphone elements are used continuously and constructively, give the Voice Tracker outstanding range and sound quality. Mr. Spencer stated, "We are very pleased with this contemporary solution to our verbal interaction system's need for clarity for robust voice recognition."
