A front - end process also an ant script runs the stylesheet to transform the input documents into the ant build file 我們設計了一個前端過程(也是一個ant腳本) ,它運行樣式表,將輸入文檔轉換成ant的build文件。
Speech enhancement as the front - end processing module is used to improve the signal - to - noise ratio ( snr ) of the input signal for recognition in the latter stages 為了讓語音識別系統(tǒng)在安靜的環(huán)境和有噪聲的環(huán)境中都獲得令人滿意的工作性能,研究了一個將語音增強器和語音識別器級連起來的系統(tǒng)。
Then this spectral subtraction method is applied to noise speech recognition system as the front - end processing . noise speech signal are processed to improve its snr before recognition . so the recognition rate can be improved in noise environments 并將改進譜減算法作為噪聲下語音識別系統(tǒng)的前端處理過程,即通過對含噪的語音進行語音增強以提高信號的信噪比,從而提高語音識別系統(tǒng)的抗噪聲性能。
