線性預測誤差單邊自相關(guān)線性預測語音前端聲學處理正則相關(guān)分析的譜變換補償特征綜合 - There are difficulties in noisy speech recognition , especially low signal - to - noise rations are more difficult . this paper describes briefly six methods for speaker - dependent noisy speech recognition isolated words . they are lpc prediction error method , one - side auto - correlation sequence lpc , acoustic front end processing , canonical correlation based on compensation method , combination of features method and increase of poles method . the experimental results show that all the six techniques can improve effectively noisy speech recognition , and the best noisy speech recognition rate is above 80 % when snr 0db
它們是：線性預測誤差法，單邊自相關(guān)線性預測法，語音前端聲學處理法，正則相關(guān)分析的譜變換補償方法，特征綜合法和同模極點增加法。實驗結(jié)果表明，這6種方法都有效地提高了噪聲環(huán)境中語音識別率，其中較好的方法在強噪聲環(huán)境中信噪比為0db的語音識別率達到80 %以上，為信噪比較低的噪聲環(huán)境中自動語音識別展現(xiàn)了美好前景。 - It's difficult to find front end processing in a sentence. 用front end processing造句挺難的
