As a basis of multimedia communication , speech coding becomes the focus of discussion 語(yǔ)音編碼作為多媒體通信的一個(gè)重要環(huán)節(jié)正受到人們的廣泛關(guān)注。
In this paper , we realize the algorithms . chapter 1 presents the development of speech code 在本論文中我們實(shí)現(xiàn)了其軟件編解碼,合成的語(yǔ)音有較高的編碼質(zhì)量。
G . 728 was the only 16kbit / s itu recommendation in the low delay speech coding algorithms at present G . 728是目前低延遲碼激勵(lì)話音編碼算法中唯一的一個(gè)16kbit s的國(guó)際標(biāo)準(zhǔn)。
With the development of the telecommunication network , high quality speech coding at low bit rates has become research focus 隨著通信網(wǎng)的不斷發(fā)展,高質(zhì)量的低速率語(yǔ)音編碼成為目前研究的熱點(diǎn)。
Robust speaker verification in low bit rate channels the influence of speech coding on text - independent speaker verification was studied 研究了多種低速率信道環(huán)境下,語(yǔ)音編碼對(duì)與文本無(wú)關(guān)說(shuō)話人確認(rèn)的影響。
The aim of research on speech coding is to obtain high quality speech coding at medium and low rate , namely at rate of 16kb / s or below 如何在中低速率( 16kb s以下)上獲得高質(zhì)量的語(yǔ)音編碼,一直是語(yǔ)音編碼研究的主要目標(biāo)。
Currently , research focuses of industry include speech coding with low bit rate , low delay , low complexity and good perceptual quality 比特率低、時(shí)延小、復(fù)雜度低、音質(zhì)又好的編碼方法是目前國(guó)內(nèi)外民用工業(yè)研究的熱點(diǎn)。
The result of simulating examination makes this system obtain good rebuilding speech coding quality which comply with g . 729 模擬試驗(yàn)結(jié)果表明,此編碼系統(tǒng)獲得了較好的重建語(yǔ)音質(zhì)量,能夠達(dá)到g . 729語(yǔ)音編碼標(biāo)準(zhǔn)所要求的語(yǔ)音質(zhì)量。
The paper consists of the following parts : firstly , the overview of basic theory of wideband speech coding and g . 722 . 1 coding algorithm is introduced 本文首先介紹了寬帶語(yǔ)音壓縮的基礎(chǔ)理論知識(shí)以及寬帶語(yǔ)音壓縮標(biāo)準(zhǔn)g . 722 . 1的算法原理。
Speech coding is an application of data compression of digital audio signals containing speech. Speech coding uses speech-specific parameter estimation using audio signal processing techniques to model the speech signal, combined with generic data compression algorithms to represent the resulting modeled parameters in a compact bitstream.
