NCT's Echo Cancellation Technology Gets Approval From Texas Instruments (January 4, 2006)

NCT, has today announced that its ClearSpeech Acoustic Echo Cancellation products for both hands-free and hand-held devices have passed the Texas Instruments (TI) TMS320 DSP Algorithm Compliance Tests for the C55 architecture and have been accepted into TI's eXpressDSP program.

This brings the total number of NCT's eXpressDSP compliant products to eight. As eXpressDSP compliant products, NCT's technology is easier for customers to integrate into their systems, accelerating their time to market and helping them meet consumer expectations for high quality voice-based communications devices. For customers wishing to evaluate these products, executables for the TMS320C5510 DSP STARTER KIT are available.

With the increasing expectations for high quality mobile communications systems, the demand for advanced signal processing algorithms that can be rapidly integrated into existing and new product lines to improve communication quality has increased dramatically. NCT's porting of its powerful ClearSpeech echo and noise reduction technology to the eXpressDSP standard represents an important stage in their 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. 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 NCT has ported their 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, ClearSpeech is able to vastly improve voice quality in a diverse range of communication systems.
