- European digital cellular telecommunications system - half rate speech - part 4 : comfort noise aspects for the half rate speech traffic channel ; english version ets 300581 - 4 : 1995
欧洲数字移动电话远程通信系统.半价话务.第4部分:半 - Two elderly neighbors warmed the house from the sides and soon she would hear the comforting noises of the boiler rousing itself into life
两个年老的邻居在墙的那边起火烧开水暖和了屋子，不久她就听到锅炉欢快地热腾起来，发出令人欣慰的声音。 - The basic characteristics of the current data network are point - to - point , connectless , doing one ' s endeavor , no quality of service , etc . these characteristics do not meet the requirement of real - time services , therefore , the realization of voip need support of the some key technology . these technologies includes : speech sound coding and data compression , real - time transmission and control , mute compression and multicast , acoustic - echo cancellation and comfort noise generator , dynamic monitor and guarantee of quality of network service , as well as , the compatible of different network and different protocol with each other
但现有的数据网络的基本特性：点对点的、无连接的、尽力而为的、没有服务质量保证等特性并不适合与实时的业务要求，因此voip的实现需要一些关键技术的支持，这些技术包括：语音编码和压缩技术、实时传输和控制技术、组播技术、静音压缩和舒适噪声生成技术、回声消除技术、网络服务质量的动态监测和保证技术、以及不同的网络、不同的协议之间的互连互通等等。 - According to the project of adaptive multi - rate speech coding ( amr ) being put forward by the third generation group of the mobile communication , this paper takes the principle of the speech arithmetic as the base , studies the technologies including the source controlled rate , voice activity detector , comfort noise and the error concealment unit in amr , discusses its the characteristic of adaptation and analyses its performances particularly . amr c codes are researched carefully through the modules being divided into and debugged under the tms320c54x provided by the ti corporation , and optimized in selecting the method of c code embedded assembler codes and simplified in the search codebook combining with the theory of speech coding , which are based on the realization about theory and practice of the optimization of amr speech coding
从自适应多码率语音编码算法的c代码出发，对它进行模块划分后作了系统分析，将其在vc下调试通过，进一步在ti公司提供的tms320c54x环境中进行调试，结合语音编码理论，对算法进行优化，采用了在c代码中嵌入汇编和简化自适应码本和固定码本搜索的方法，部分地提高了c代码效率，为实现自适应多码率语音编码的优化奠定了理论和实践基础。
