The voice processing software uses vo-coders that work with another partner of NXP. Initially, the kit will support G.711 and G.729 codecs with ILBC (Internet Low Bit-Rate Codec) and possibly others added in the future. The kit also includes either accura-speak or line-echo cancellation for good voice quality. The solution is associated with specific ColdFire part numbers, MCF53281 or MCF53721. When these parts are purchased, they include the silicon and any charges associated with the software. So it is important to know that individual pieces don’t have to be licensed separately; everything comes associated with the part number.
