摘要
Adaptive multi-rate wideband (AMR-WB) speech codec is the first standard for both wired and wireless universal broadband speech codec. Real-time implementation of AMR-WB algorithm in DSP has important practical significance and will accelerate its course of practice. The paper first designed the hardware platform and system software structure for real-time implementation of the AMR-WB algorithm, then introduced the transplantation of AMR-WB algorithm to the designed hardware system. The paper next discussed the real-time implementation of optimized algorithm on the hardware platform. Objective test results indicated the decoded speeches of real-time platform were bit exactly the same as test sequences. Synthetic speeches of real-time platform were very good in restoring the speaker's voice characteristics by good intelligibility and naturalness.
