Alango's Speech Harmonics Enhancement and Restoration Algorithm Now Available on Texas Instruments' most Popular DSP

Israel - March 2, 2003 - Alango, (www.alango.com) a provider of voice and music signal processing and software for data analysis, announced today that its Speech Harmonics Enhancement and Restoration (SHER) algorithm is available to customers using Texas Instruments' (TI) TMS320C54xTM digital signal processor (DSP) generation, one of TI's most popular platforms.

The SHER algorithm has achieved eXpressDSPTM compliance from TI which ensures that the patent-pending algorithm is compatible and will easily integrate into customer applications using TI's C54xTM DSP generation of programmable DSPs and chips sets for voice and music signal processing. SHER digital signal processing technology reconstructs and enhances low frequency speech harmonics below 600 Hz to significantly improve communication in noise-filled environments.

"eXpressDSP compliance allows our customers to be confident that our algorithms are easy to integrate into TI DSP-based applications demanding improved sound quality," said Alexander Goldin, President & CEO, Alango. "We are excited to work with Texas Instruments on new communications reference designs to enable customers a smooth and rapid integration process."

The eXpressDSP compliance program ensures algorithms are written according to the TMS320 DSP Algorithm StandardTM, a set of coding conventions and application programming interfaces (APIs). This allows algorithm creators to "wrap" the code for system-ready use allowing for interoperability between algorithms. Instead of re-engineering algorithms for each different system, algorithms are written once and easily reused by integrators. Customers who use eXpressDSP compliant algorithms gain accelerated time to market, improved ease of use through a wide selection of value added tools in a unified environment, minimal algorithm configuration time and an additional level of comfort knowing that the product has passed compliance testing for interoperability.

"We are eager to welcome Alango to our extensive network of Third Party technology partners. The SHER software provides customers with improved sound quality for voice and music applications as well as reduced development costs and increased time-to-market," said Richard Faust, C54x product marketing manager, TI.

The Speech Harmonics Enhancement and Restoration (SHER) technology utilizes harmonic structure of speech so that if and when low frequency speech harmonics is lost due to communication channel or high-level noise, this information is accurately restored using higher harmonics. The restoration algorithm utilizes Alango patent pending principal allowing exact reconstruction of speech harmonic structure in the low frequency region (below 600Hz).

The SHER technology is also available on STMicroelectronics Euterpe voice processor as a standalone module and as part of the Alango hands-free car kit reference design. SHER technology is also designed to for use with other Alango technologies - the Signal Enhancement & Noise Suppression (SENS) package, the Autodirective Dual Microphone (ADM) and Echo Cancellation (EC).
