Based on the pdf of speech parameters, a new neural network, Classification Neural Network-CNN, is presentedin the paper, and the quality for apeech coder makes improvement significantly.

• 本文建立在MPE-LPC语音编码器中对数面积比参数(G参数)和间接激励参数(R_(Lx)参数)的概率分布特性上；提出了一种新的综合神经网络结构-分类神经元网络(Classification NeuralNetwork-CNN)；使编码器质量有了明显的提高.
