Real-time implementation of 4.8/3.6/2.4/1.2 kb/s high quality multi-rate speech coding on TMS320C31
This paper presents a modified multiband excitation (M/sup 2/BE) speech coding algorithm which can achieve high-quality synthesized speech at 4.8, 3.6, 2.4 and 1.2 kb/s. The computer simulation results show that the synthesized speech is quite natural even at rate as low as 2.4 kb/s. This algorithm has been successfully implemented on a single TMS320C31 floating point processor and informal listening test demonstrates that the speech quality is quite good between 1.2-4.8 kb/s.
