  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

    其中對編解碼的設計採用優化g . 729a代碼達到設計要求,並在此基礎上加入g . 729b的靜測模塊,以進一步降低網路傳輸帶寬;對回聲消除的設計採用nlms演算法,通過設計自適應fir濾達到回聲消除目的;對雙多頻設計,信號發生端採用構造靜態參數表並通過二階正弦振蕩產生信號,信號測端提取頻率信息以測信號;對呼叫進程設計,除了類似雙多頻的信號發生及頻率測設計外,還需要測信號持續時間,作者設計了一種基於匹配狀態表的方法以測信號持續時間。
