Texas Instruments Inc. (TI) has announced the availability of a robust set of voice and fax processing modules used to create voice transcoding and VoIP media gateway solutions.

Based on TI�s Telogy Software, Voice Library Version 1.0 (VoLIB) and Fax Library Version 1.0 (FAXLIB) are available for the first time in object code for TI�s TMS320C55x ultra-low power (ULP) and TMS320C64x+ digital signal processors (DSPs). Merged with TI�s DSP technology, these voice processing modules reduce product development time and offer an open environment for OEMs to differentiate their products with specific modules from TI�s voice and fax libraries.

�Our customers not only have the flexibility to select from a range of TI devices in the C55x and C64x+ DSP platforms, but they also have a path to migration with our newly announced TMS320C66x multicore DSPs as these libraries become available on C66x devices next year,? comments Ramesh Kumar, multicore & media infrastructure business manager, TI.

The voice processing modules augment the family of codecs available to developers on TI�s website. VoLIB modules consists of: Telogy Software Line Echo Canceller (ECU); Tone Detection Unit (TDU); Caller ID Detection/Generation (CID); Tone Generation Unit (TGU); Voice Activity Detection Unit (VAU); Noise Matching Functions; Packet Loss Concealment (PLC); Voice Enhancement Unit (VEU).
