智能化多媒体教室中语音传输系统的设计与实现

Design and implementation of voice transmission system of intelligent multimedia classroom

语音信号在智能化多媒体教室中起着非常重要的作用。本文从语音模拟信号和数字信号的传输两个方面,分别阐述了语音传输系统的构成和实现:模拟信号在教室内传输、数字信号在网络中传输。不同的传输方式,使用的设备和技术手段不同,最终都以获得优质语音信号,促使多媒体教室正常运行,为教育教学服务为目的。

Speech signal in intelligent multimedia classroom plays a very important role.This article interprets the constitution and implementation of voice transmission system respectively from two aspect,transmission of analog and digital signals,which can be explained as that analog signal transmits in classroom but digital signal in network.When we choose different transmission methods,the technological means and appliances we use are different also.However,whatever we use is for the sake of optimizing of voice signal,guaranteeing the operation of multimedia classroom and providing better teaching service.
