"NCT's integration of its ClearSpeech noise reduction technology with the OSEck RTOS and development environment is an important initial step for ensuring that complex DSP-based communications devices can take full advantage of our noise reduction, echo cancellation and signal conditioning technology," said Dr. Gillian Davis, managing director of NCT.
ClearSpeech is a suite of complex, highly refined software algorithms that provide echo cancellation, signal conditioning and up to 18 dB of noise reduction for human listeners and speech recognition systems. ClearSpeech noise reduction technology is used to enhance voice quality in millions of products around the world, including 3G mobile phones, hands-free voice recognition systems, and Formula 1 team communication systems.
"We are very pleased to see NCT port their best-of-breed ClearSpeech technology to our OSEck real-time operating system," said Joel White, UK manager at Enea Embedded Technology. "OSEck and ClearSpeech provide an excellent platform for developing and deploying a wide range of high-quality, DSP-based voice processing systems."
OSEck (OSE Compact Kernel) is a DSP-optimized version of the full-featured OSE RTOS. Occupying less than 4 kbytes of memory (in a minimal configuration), OSEck delivers fully pre-emptive, event-driven real-time response, and features built-in error detection and handling. OSEck and OSE utilize the same LINK-based message-passing technology, which simplifies interprocess communications and makes it easy to combine general-purpose CPUs and DSPs in the same system. OSE and OSEck also use the same API, enabling designers to leverage the memory protection facilities of OSE on the host processor and the hard real-time attributes of OSEck on the DSP without having to learn multiple programming environments.
ClearSpeech noise reduction technology is available immediately from NCT for evaluation on the OSEck RTOS. Royalties start at $1 per unit/channel for volumes greater than 100k units/channels. Contact firstname.lastname@example.org for further information.
Trading since 1990, Noise Cancellation Technologies (Europe) Ltd, (NCT), is a world leader in the development of technologies for the removal of noise and echo from communication systems such as mobile phones, radio systems, intercoms, hands-free kits and voice recognition systems. By developing advanced software algorithms that run on DSPs (digital signal processors) and CPUs, NCT has enabled some of the world's top manufacturers to deliver high quality voice-based communication systems.
