So in this paper a recognition algorithm of heart sound based on probabilistic neural networks ( PNN) is proposed to improve the accuracy of heart sound recognition.

在综合分析以前各种心音识别算法的基础上，本文提出了一种基于概率神经网络PNN的心音信号识别算法，将概率神经网络作为心音信号分类器，取得了较好的识别效果。

The extraction of features of Voiceprint Recognition System. The paper describes the sound channel model, Linear Predictive Coding ( LPC), Linear Predictive Cepstral Coefficients and Mel-Frequency Cepstral Coefficients. 2.

详细阐述了声道模型、线性预测编码（LPC）分析、LPC倒谱系数、Mel倒谱系数的求解；2、声纹识别的识别方法和模型。

This finding indicates that our brains process sound based not only on the audio input they receive, but also on our listening goals. And it could lead to speech recognition systems that are accurate in crowds-even at a cocktail party.

这一发现表明，我们的大脑在处理声音的时候不仅基于它们接收到的音频输入，还基于说话人的不同。这一研究成果有助于开发出适用于嘈杂人群甚至鸡尾酒会的语音识别系统。
