The linear predictive coding synthesis (LPC) parameters are extracted by using 23.05 k bit/s mode of adaptive multi-Rate wideband speech coding technology (AMR-WB). The synthesis results show that the speech synthesized are similar to the sample speech in time and frequency domain, in addition, the synthesized speech sound like sample speech well. The speech synthesized can well retrieve the characteristics of the sample, and gain good synthesis results. The algorithm meets the requirements of speech synthesis system which needs lower decoder complexity. So it is feasible that the AMR-WB algorithm were applied to linear predictive coding speech synthesis to synthesize the speech.
