3 December, 2019 – Cambridge audio technology specialist AudioTelligence will be among a Department for International Trade delegation of British companies showcasing UK innovation at the Consumer Electronics Show in Las Vegas in January.
AudioTelligence will be staging demonstrations of its technology breakthrough that it describes as autofocus for sound – an ‘acoustic lens’ that enables your home assistant, smart speaker or in-car voice control system to focus on what you are saying when there is a lot of background noise.
It is set to end the frustration of shouting at your digital assistant device when it can’t hear you over your favourite music track. It can even enable you to hear the conversation when a friend rings you from a noisy coffee shop or when you're in the car on a busy road.
"They say seeing is believing – but, in this case, hearing is believing," said Ken Roberts, CEO of AudioTelligence. "Visitors to our stand at CES will be able to try out the technology for themselves and hear the difference with and without our technology. Our team will be on hand to discuss potential use cases – or any specific requirements from companies interested in incorporating our technology in their new generation of smart products."
What’s unique about the AudioTelligence solution is that it uses a statistical approach to solve the problem of background noise. Its data-driven blind audio signal separation technology is able to ‘listen’ to a real-world acoustic scene and identify the prominent sources of sound, including echoes and reflections. Sophisticated algorithms enable it to cancel out the unwanted interference that often makes effective speech recognition impossible. The system is also adaptive – so any new background noises that appear are also eliminated in real time.
The solution works with as few as four microphones and doesn’t need calibrating or training – so existing devices can be easily reconfigured with a software update. The algorithm has a latency of just five milliseconds – making it ideal for real-time applications – and it’s designed to obtain the best possible performance from the available processing power.
AudioTelligence is a spin-out from CEDAR Audio – a world leader in audio restoration, speech enhancement and audio forensic investigation. The start-up raised £3.1m last year from Cambridge Innovation Capital and Cambridge Enterprise to fund its ambitious growth plans and meet the demand for its technology.
The UK pavilion at CES 2020 (7-10 January) is at the start-up arena Eureka Park at Sands Expo, Hall G. AudioTelligence is on stand 51902/E.
