NCT Licenses Voice Technologies to Trilogy

NCT (Europe) LtdNCT (Europe) Ltd—July 20, 20060

Cambridge technology company NCT has licensed its voice technology products to Trilogy Communications Ltd, a world class supplier of Audio Communications and infrastructure equipment. Trilogy has licensed NCT’s Noise Reduction (ASF), Speech in Noise Detector (SND) and Intelligent Squelch Filter (ISF) algorithms to provide DSP-based voice conditioning on a system that interfaces to UHF and VHF radio base stations.

NCT are recognized as a world leader in the provision of voice technology. Their noise reduction, echo cancellation and signal conditioning software is used in millions of 3G phones and hands-free car kits around the world. Either integrated into audio chips or into customer software applications, NCT’s ‘ClearSpeech’ technologies remove background noise and acoustic echo, to enable human listeners and voice recognition systems to hear the talker with optimum clarity.

“We need algorithms such as noise reduction, to improve the quality of the received speech in the presence of radio artifacts and background noise,” said Tim Hardisty, CTO at Trilogy. “We also need the reduction of noise from sources such as appliance sirens and fire alarms, and improved voice detection to reliably provide a binary indication to our control software when voice is present. NCT’s offerings fit the bill very well.”

Trilogy’s engineers are using a hardware platform based on the BlackFin BF533 DSP, serving 8 radio channels. During the recent devastating Hurricane and subsequent flooding in New Orleans, Trilogy equipment has been a key part of the relief effort. With all fixed communications infrastructure out of action, the National Guard flew in four of their IC4U tactical communications units from California. These mobile trucks use Trilogy’s Mercury IP communications to provide interoperability between disparate radio systems being used by the many relief agencies brought in to help. In addition, the IP satellite reachback capability allows communication with the Central Command headquarters set up to manage the emergency.

“We are very pleased that Trilogy has chosen our voice technologies,” said Dr Gillian Davis, Managing Director of NCT. “Trilogy develop impressive communication systems that work in demanding environments, for them to have chosen our voice technology to enhance system performance is great feedback for the NCT development team and confirmation that we remain very much a world leader in this field.”
