根据语音信号的特点，提出了适应协同工作环境需求的一种语音编码器，并且完成了该语音编码器的仿真。仿真测试结果表明，编码器延时小、质量高、复杂度低，且可自适应语音流的时变特性，是一种有意义和有价值的编码器。
According to the characteristics of speech signal, a speech encoder adapting to the requirements of collaborative work environment is proposed, and the simulation of the speech encoder is completed. Simulation results show that the proposed encoder is a meaningful and valuable encoder with small delay, high quality, low complexity and adaptive time-varying characteristics.
