MENLO PARK, Calif.--(BUSINESS WIRE)--July 30, 2002--Nuance
(Nasdaq:NUAN), the speech software experts, today announced that the
company's speech recognition software has been selected for Adacel's
MaxSim, the leading air traffic control simulator. This new
voice-driven system will be used to train air traffic control
personnel, including those in the U.S. military. Since November 2001,
Adacel has been selected for North American civil and defense air
traffic simulation and management systems worth over $100 million,
including programs for the U.S. Air Force, U.S. Army, and the Federal
Aviation Administration. The MaxSim product was developed in
combination with Nuance partner Newfound Communications, Inc., a
pioneer in VoiceXML-based speech technologies and services.
Adacel MaxSim is a highly realistic training system that mimics
the actual experience of an air traffic controller. Featuring computer
generated radar screen images, MaxSim enables students to verbally
guide aircrafts into and out of assigned radar sectors through the use
of Nuance 8.0 speech recognition software. Newfound Communications
worked with Adacel to achieve the multi-modal solution with
unprecedented accuracy to recognize and instantly respond via visual
changes in the radar images to the standard voice command and control
phrases used by air traffic control operators, such as "sierra two
six, you are number three to land; follow three eight five on
downwind, over."
"There are a number of challenges inherent in developing a
speech-enabled air traffic control application such as Adacel MaxSim,
such as the proper management of large and complex grammars," said
Lionel Leveille, president and CEO of Adacel Inc. "We tested a number
of speech solutions and found Newfound and Nuance to be the only
providers that could deliver the speech recognition accuracy and
system scalability we required."
U.S. air traffic controllers ensure the safety of nearly two
million aviation passengers per day -- or almost 700 million people
per year. Control towers are stressful, high-energy environments where
controllers know they do not have a margin for error. The
Nuance-powered Adacel MaxSim simulator training system helps
prospective air traffic controllers prepare for days full of
fast-paced radio conversations with hundreds of aircraft flying high
in the sky.
