  1. Section ii describes the design approach and implementation of speech module on mcf5249 coldfire core. the speech codec optimizes g. 729a codes and added voice activity detection of g. 729b to save bandwidth ; the implementation of acoustic echo cancellation uses nlms algorithm and it can reduce echo though designing adaptive fir filter and speech detector ; the dtmf and cpt generate signal using two second order digital sinusoidal oscillators and detect signal by picking up the frequency information. but only get the frequency information is not enough in cpt detector, this thesis introduces a method

    其中對語編解碼器的設計採用優化g . 729a代碼達到設計要求,並在此基礎上加入g . 729b的檢測模塊,以進一步降低網路傳輸帶寬;對回聲除器的設計採用nlms演算法,通過設計自適應fir濾波器和語檢測器達到回聲除目的;對雙多頻設計,信號發生端採用構造態參數表並通過二階正弦振蕩器產生信號,信號檢測端提頻率信息以檢測信號;對呼叫進程設計,除了類似雙多頻的信號發生及頻率檢測設計外,還需要檢測信號持續時間,作者設計了一種基於匹配狀態表的方法以檢測信號持續時間。
  2. To improve the speech quality, it is necessary to adopt such speech processing techniques like speech compression, voice activity detection, echo cancellation, jitter buffer and so on

    為了提高語質量,需要採一系列的語處理技術,主要包括語壓縮技術、處理技術、回聲除技術、抖動緩沖技術等。
