自从电话发明以来,语音通信一直是现代各种通信系统承载的一项重要的、必不可少的业务.随着通信网络用户数量的增加,网络业务综合化、多样化,网络宽带与系统容量、服务质量的矛盾日益突出,传统的语音压缩编码已经不能满足不断通信的要求.因此,如何用基于矢量量化技术的语音编码技术来提高通话质量和增加系统容量是摆在我们面前的一个重要课题.
论文首先从语音压缩编码出发,简单叙述了语音压缩编码的理论基础、分类和发展,再介绍了矢量量化技术的基本原理和它的关键技术,然后进入本论文的主题-基于矢量量化技术的语音压缩编码.在这一部分主要叙述了矢量量化技术在三种语音压缩编码中的应用,最后介绍了这部分的发展及未来展望.
矢量量化技术将在语音编码的应用研究将朝着多领域、系统化、标准化和实用化方向继续发展.

Answer 1

Since telephone invention,pronunciation communicate by letter is always important ,essential one business that modern various communication system bears the weight of.Synthesize-rization ,diversify with communications network consumer quantity increasing by ,network business,the network broadband is outstanding gradually with system capacity ,the service quality contradiction ,the tradition pronunciation compression code already can not satisfy the unceasingly communicative request.Therefore ,how mass and the capacities increasing system are to lay bare a important problem before us with communicating by phone owing to that the vector quantization technology pronunciation code technology comes to improve.
The thesis sets off from pronunciation compression code first ,the rationale having narrated the pronunciation compression code's simplely,classifies and develops,compression code having introduced basal principle and its vector quantization technology key technology,and then the vector quantization technology-based subject- pronunciation entering a thesis again.Pronunciation has compressed application in code in this part of the technology having narrated the vector quantization mainly in the three kinds ,has introduced that development of this part and future look into the distance finally.
The vector quantization technology will will continue developing to much field ,systematization ,normalizing and pragmatic-rization direction in pronunciation code application study.
