Many research topics had focused on how human can input information into a computer as quickly as possible with high accuracy rate in an easy way. the recognition of handwritten word is one possible solution. but the recognition of nature word writings encountered lots of problems, such as, low writing speed and low recognition rate
手寫體識別的研究為解決這個問題提供了一個必要的條件，但是由於傳統文字的特點，使得識別的正確率很難取得突破性的進展，而且傳統文字記錄的緩慢速度也制約了它作為高速錄入的解決方案的可能。 -
One is using the autocorrelation function to detect the speech terminal, the other is using the coefficients based on the one - sided autocorrelation sequence to replace the original speech signal and then extract the speech feature to recognize. isolated word recognition experiment based on dtw shows : it can reduce the disturbance of noise effectively and get the high recognition rate. it is of great advantage to apply when snr signal to noise rate is low
對含噪語音在自相關域上進行處理，以其自相關函數值為參數進行端點檢測，以基於單邊自相關序列的lpc倒譜系數作為語音的特徵參數進行語音識別，實驗表明：這種方法較好地消除了噪聲對語音信號的干擾，並獲得了較高的識別率。
