Cannes, France, April 26, 2007 – Nuance Communications, Inc. (NASDAQ: NUAN), a leading supplier of speech and imaging solutions, today announced the results of two amazing match-ups of “man vs. machine” held at Conversations Europe, its annual European speech conference. In the Amazing Race Part Two, Nuance challenged one of the winners of a recent national texting competition and then expanded the competition to include competitive driving, demonstrating a broad range of speech applications. The event was a continuation of the October 2006 Amazing Race that pit Nuance® Mobile Messaging against the Guinness Book of World Records’ fastest text messager (see www.youtube.com/watch?v=-L4Jk6GDud0).

Eli Tirosh, the recently crowned West Coast Champion of a national texting championship, raced against a Nuance employee demonstrating Nuance® Mobile Messaging, the speech recognition technology that allows mobile phone users to create and send text messages using speech. Contestants were scored based on the time required to complete the entry of the exact text message, including appropriate spelling, punctuation and capitalization. Nuance Mobile crushed the texting champion in each of the two rounds of messaging:

Message 1: “Just last week, there was a text messaging competition in New York City. Today, the west coast champion is racing against speech technology. Who will win? :-)” – Eli Tirosh 50.17 seconds; Nuance Mobile Messaging: 21.83 seconds

Message 2: “Supercalifragilisticexpialidocious – How many of you out in the audience even know how to spell that word?” – Eli Tirosh 24.00 seconds; Nuance Mobile Messaging: 13.49 seconds

In the second match-up of man vs. machine, one of Britain’s top racing drivers, Perry McCarthy, also known as “the Stig” from BBC’s Top Gear (the secret racing driver in black), took his chances against a contestant who was able to use speech recognition to conduct a number of device-related tasks in a simulated driving environment. Speed was not the critical measurement in this competition, but rather minimizing distraction and ensuring safety by allowing the “driver” to keep his hands on the wheel and eyes on the road.

Each driver received a text message with instructions to access and play a specific song. Drivers received their assignments using a Nokia 5500, one with, and one without, speech applications installed. While McCarthy needed to take his eyes off the road to read the incoming text message, the driver with Nuance® speech solutions on his phone continued to drive safely on the course while the incoming message was read aloud to him. McCarthy was then forced to navigate his iPod manually to find and play the requested song, while the Nuance driver was able to simply say the name of the song he needed to play. Due to the number of times he was forced to take his eyes and hands away from the simulated driving environment, McCarthy crashed 27 times, while the Nuance driver finished the course without any mishaps.
