With the development of digital information technology, speech coding enhances its development rapidly and plays an important role. Especially the speech coding algorithm, which has low bit rate and high quality, provides qualified multimedia services based on limited channel width. The paper studies the application of DSP technology of TMS320VC5509 in data speech coding algorithm, the overall plan of coding design, AIC23 interface design and coding algorithm. Based on these studies, it explores the optimization of coding algorithm and analyzes algorithm according to optimization results.
