NCT's ClearSpeech Noise Reduction Technology Available for Enea's OSEck Real-Time OS; Enhances Mobile Communications Voice Quality by Removing Background Noise.SAN JOSE San Jose, city, United States San Jose (sănəzā`, săn hōzā`), city (1990 pop. 782,248), seat of Santa Clara co., W central Calif.; founded 1777, inc. 1850. , Calif. -- Enea, the world leader in advanced device software, today announced the availability of NCT's ClearSpeech noise reduction technology for the OSEck real-time operating system (operating system) Real-Time Operating System - (RTOS) Any operating system where interrupts are guaranteed to be handled within a certain specified maximum time, thereby making it suitable for control of hardware in embedded systems and other time-critical applications. . ClearSpeech gives designers of OSEck-based mobile communications systems an easy way to enhance voice quality by removing background noise. NCT NCT National Childbirth Trust NCT National Car Test NCT North Carolina Theatre NCT National Coordination Team NCT Northern California TRACON NCT Noise Cancellation Technology NCT Network Control and Timing NCT Nicotine Replacement Therapy will be presenting their technology at "Building the Perfect Beast," an event focused on automotive electronics to be held near Cambridge on November 15, 2005. http://www.embedded-automotive.co.uk. "NCT's integration of its ClearSpeech noise reduction technology with the OSEck RTOS (1) (RealTime Operating System) An operating system designed for use in a real time computer system. See real time system, embedded system, process control and OS-9. 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 The elimination of an echo in a two-way voice transmission. Echo is created in the telephone company's central office switch when two-wire lines from the customer are converted to four-wire lines for backbone trunks. and signal conditioning Imagine feeding the output of a temperature sensor, which is in millivolts, to an Analog-to-digital converter to be processed. Is it possible for the Analog-to-Digital converter to process such a minute voltage amplitude? The answer is probably no. 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 Joel White, the son of author E. B. White and New Yorker Magazine editor Katharine Sergeant Angell White was a renowned U.S. naval architect known for his classic and beautiful designs including the W-Class of boats. , 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 OSE - Open Systems Environment 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 pre·emp·tive or pre-emp·tive adj. 1. Of, relating to, or characteristic of preemption. 2. Having or granted by the right of preemption. 3. a. , event-driven real-time response, and features built-in error detection and handling In television technology, Error Detection and Handling (EDH) protocol is an optional but commonly used addition to the Standard Definition-Serial Digital Interface (SDI) standard. . 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 (1) (Digital Signal Processor) A special-purpose CPU used for digital signal processing applications (see definition #2 below). It provides ultra-fast instruction sequences, such as shift and add, and multiply and add, which are commonly used in math-intensive 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.
