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
其中對語音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的靜音檢測模塊,以進一步降低網路傳輸帶寬;對回聲消除器的設計採用nlms演算法,通過設計自適應fir濾波器和語音檢測器達到回聲消除目的;對雙音多頻設計,信號發生端採用構造靜態參數表並通過二階正弦振蕩器產生信號,信號檢測端提取頻率信息以檢測信號;對呼叫進程音設計,除了類似雙音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。This kind of alarming device makes use of heat - releasing infrared transducer, which can discern the special infrared rays of the human body and transform them to electrical signals, then send the signals to single chip
利用熱釋電紅外傳感器作為探頭,進行非接觸式遠距離檢測,將感測到的紅外信息轉換成電壓信號,經過單片機處理,完成數碼顯示和語音報警功能,從而實現了防盜報警功能,達到了安全防護的目的。Pitch detection is one of the most important tasks in low - rate speech coding field. the accuracy of pitch detection will affect the performance of the whole codec
基音檢測是低速率語音編碼領域的一個非常重要的問題,準確檢測語音信號的基音周期非常關鍵,它直接影響到整個聲碼器的性能。
