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。 -
But it is not the same with surd or the alternation of sonant and surd. on the base of the acoustics, a whole linear time - varying discrete speech produce model is established through anatomising the factors including track, driving source and lip eradiation the mechanism of speech in this paper, and we draw a conclusion that the time between glottal closure is pitch period
本文從聲學理論出發，剖析了語音產生的機理，綜合考慮聲道、激勵源和嘴唇輻射三方面的因素，建立了一個完整的、線性的和時變的語音產生的離散系統模型，得出兩次聲門閉合事件之間的時間間隔就是基音周期的結論。 -
In this paper, we use full pole model to obtain speech signal lpc, then deduce it ' s lpcc, and we use the lpcc difference to describe speaker ' s track dynamic movement
本文應用全極點模型，提取語音信號的線性預測系數，並推導出其倒譜系數，獲得線性預測倒譜差分，用以描述說話人聲道的動態變化。 -
In this scheme, the speech residual signal is synthesized directly using magnitude spectrum and phase track where there are continuous changes for pitch between frames, while the speech residual signal is synthesized using phase intergradations with a burst of the pitch
在該方案中，當幀間的基音周期連續變化時，語音殘差信號由幅度譜和相位軌跡直接合成，而當基音周期發生跳變時，則利用相位過渡過程合成語音殘差信號。
