Based on all these above, the results of main research are as follows : ( 1 ) a voice activity detection ( vad ) algorithm based on dct band - partitioning spectral entropy is proposed
本文以此為基礎,並取得了如下研究成果: ( 1 )提出了基於dct分帶譜熵的語音檢測演算法。 -
On the basis of analyzing noise property, this thesis emphasizes on two noise estimation methods : classical method based on voice activity detection ( vad ) and the latest method based on optimal smoothing and minimum statistics. some improvements have been proposed to enhance the vad ’ s performance based on lpc cepstrum coefficients
2 .在分析噪聲特性的基礎上,重點研究了基於語音活性檢測和基於連續更新噪聲譜的兩種噪聲參數估計方法,並提出了將能零積的思想應用到基於lpc倒譜系數的語音活性檢測演算法中。
