Since the Mixed-Excitation Linear Predictive (MELP) Vocoder was selected as the new 2.4Kbps Federal Standard speech coder in 1996[1], the very low bit rate speech coding method has become new tendency for research. This paper presents a new LPC vocoder model(FBLPC) based on forward-backward waveform prediction[2] for very low bit rate speech coding. Besides, we use the technology to accomplish the application system named phone-to-phone over internet.
