Implementation of a Low Bit Vocoder Based on the Improved MELP Algorithm

Ma Jinquan,Gao Shihai,Zhang Lianhai(Information Engineering University of PLA,Zhengzhou 450002,China)  
A MELP vocoder algorithm at 0.6 kb·s-1 is proposed.This algorithm organizes four subframes into a superframe and classifies the superframe into multi-modes on the basis of the clarity/turbidity property with different modes adopting different quantified united coding scheme.It is implemented with DSP TMS320C5416 in real-time,and it can be performed with articulate voice and good naturalness.
