NCT's porting of its powerful ClearSpeech echo and noise reduction technology to the eXpressDSP standard represents an important stage in the company's efforts to make ClearSpeech readily available to this very competitive market.
The TMS320 DSP algorithm standard, defines a set of algorithm programming rules, coding conventions and application programming interfaces (APIs) for algorithm creators to use.
By following these standards, algorithms can be easily integrated by OEMs across a wide range of products based on the same architecture, speeding the time to market.
"We are confident that by following TI's algorithm standards, our customers will find it easier to implement our technology", said Dr Gillian Davis, Managing Director of NCT.
"Our "ClearSpeech echo and noise reduction for the C55 architecture provides up to 50dB of echo cancellation and 18dB of noise reduction and can handle echo path lengths of 8 and 64ms, offering optimum performance for both headset and hands-free applications".
"TI is excited that NCT has ported its Clearspeech echo and noise reduction technology to the eXpressDSP Algorithm standard".
"This may smooth NCT's algorithm integration into end products and reduce customers' design time and costs", said John Dixon, Texas Instruments DSP Business Development Manager EMEA.
ClearSpeech is a suite of complex, highly refined software algorithms that provide noise cancellation for human listeners, noise cancellation for voice recognition, echo cancellation and signal conditioning.
By removing background noise and voice echo, it is able to vastly improve voice quality in a diverse range of communication systems.
