NCT specializes in providing software components that provide noise and echo reduction and speech enhancement for communication system developers. Their ClearSpeech product exists in millions of 3G mobile phones and hands-free systems around the world and is even used in the extremely noisy environment of motor racing, to enable clear communication between the drivers and the pit crews.

"We live in a noisy world, so technology such as ClearSpeech has become an essential component to enable communication system manufacturers to meet consumer expectations," said Nathan Blundy, DSP Audio Applications Engineer.

"To develop this technology, the very best of the disciplines of advanced mathematics and software programming have to be brought together, along with a wealth of experience and understanding of the environments in which these systems are used. This presentation will provide an overview of how we overcome noise and echo in a range of applications that include in-car voice recognition, hands-free systems, wireless Bluetooth headsets, emergency services radio systems and even a 'Drive Thru' restaurant intercom system.”
