Speech codecs based on this new BSP excitation have the advantages of low complexity and low delay. Experiment results prove that such a new speech codec can provide highly intelligible synthesized speech below 3 kbit/s.

• 实验结果表明 ；BSP编解码器由于求取BSP激励参数的计算量较小 ；因此处理速度快、时延小 ；同时编码速率在低至 2 .；65kbit s时；具有较高的合成语音质量。
