%X In order to meet the applications of wireless communication, a new speech algorithm based on sub-frame joint coding is proposed in this paper. This new algorithm improves several aspects such as model structure, LSP quantization and coding. This algorithm has been implemented on TMS320VC5416 DSP processor. Informal listening testing results show that the intelligibility and naturalness performances of the 600b/s speech coding algorithm are close to those of the 2.4kb/s LPC algorithm, while the rate is oidy 1/4 of LPC algorithm.
