  1. On the basis of the study on the speech coder algorithms, paper describe an advanced method of developing dsp system software, and as the guidlines, we developed the programme of whole decoder unit. paper stress on analysis of the ecu in decoder unit. aiming at amr algorithms disadvantage of angularity of synthetical speech, paper study on the specutral extrapolation which apply to extrapolate reflect coefficient of track model to make error conceal processing of amr. at last paper analyze existing echo cancellation algorithms using on mobile communication system

    在此基礎上，描述了一種較為先進的大型dsp系統程序開發策略，並以此為指導思想，以美國ti公司c6000dsp開發平臺開發出了整個amr解碼器單元的系統程序。論文對amr解碼器的誤碼隱藏處理單元進行了重點分析，針對原有演算法合成語音自然度不好的缺點，論文研究了將譜外推法應用到amr演算法中外推出聲道模型反射系數參數進行誤碼消除處理。
  2. Then this spectral subtraction method is applied to noise speech recognition system as the front - end processing. noise speech signal are processed to improve its snr before recognition. so the recognition rate can be improved in noise environments

    並將改進譜減演算法作為噪聲下語音識別系統的前端處理過程，即通過對含噪的語音進行語音增強以提高信號的信噪比，從而提高語音識別系統的抗噪聲性能。
  3. The implementation of such a system is extremely complicated due to three factors : the impulse response of a lrm system have a duration of several hundred milliseconds, the system has to be adaptive, and the adaptation has to be performed with a speech input the traditional adaptive algorithms such as lms and nlms can not obtain the satisfied result in the real - time acoustic echo cancellation processing

    但由於聲回授通道的特殊性和復雜性，普通的自適應演算法無法滿足要求，必須採用一些十分復雜的演算法，這樣一來，實時性的問題變得十分突出。快速lms newton演算法的提出，給自適應聲回波對消問題的解決開辟了新的途徑。該演算法集lms演算法的簡單易行性和newton演算法的快收斂性為一體，是一種非常有應用前景的自適應演算法。
  4. The informal subjective test in real - time processing indicates that the synthetic speech quality of amr vocoder is better than it of rpe - ltp in gsm system, achieving toll quality, that can apply to devices employing the amr vocoder within the 3gpp system in terms of software and hardware

    實時處理的非正式主觀測試表明，合成語音質量優于gsm的rpe - ltp的語音質量，達到長途語音質量，完全可以實際應用，為第三代移動通信中聲碼器設備的研製奠定了良好的軟體和硬體基礎。
  5. European digital cellular telecommunications system - half rate speech - part 1 : half rate speech processing functions ; english version ets 300581 - 1 : 1995

    歐洲數字移動電話遠程通信系統.半價話務.第1部分:半
  6. Design of a speech processing system based on dsp

    的語音處理系統設計
  7. A new speech processing system

    一種新型語音處理系統
  8. It is essential for speech processing system to have robust speech detection. a pca ( principal component analysis ) - based speech detection was proposed. we get a very good result form the examination of using this method

    本文提出了將pca應用於語音檢測，實現了語音和非語音的正確檢測，並通過實驗證明了這種方法是可行的，而且檢測效果比較好。
  9. Secondly, the design of the wideband speech processing system based on dsp is described. finally, the haredware and software of the system is expatiated, which includes the design of system architecture and its intefaces ; the programming and debugging of software in dsp, the driver of the speech gathering card and the interrupt service of tms320vc5416

    接著講述了基於dsp的寬帶語音處理系統的總體設計，包括系統架構設計、演算法與晶元選型等。然後是寬帶語音處理系統的硬體組成與介面設計。最後是寬帶語音處理系統的軟體實現，包括dsp的數據接收與發送的實現， dsp主程序與採集卡驅動程序的設計、編程與調試， dsp中斷處理的實現等。
