This paper raised a new way for overlapping speech segregation based on sound localization cues. in this paper, we first divide the speech stream into some time - frequency regions and calculate the itd and iid of each region. then the notion of a " time - frequency " binary mask is given, which selects the target if it is stronger than the interference in a local time - frequency region
然後求取每個小片段上的itd (到達雙耳時間上的差異性)和iid (到達雙耳強度上的差異性)值,經過實驗證明某個片段上的itd值和iid值與該片段上的信噪能量比是單調遞增關系,因此通過和域值的比較,得出掩蔽系數,來判斷每個小片段具體是屬于哪個聲源。Speech enhancement method based on masking properties of the human auditory system is used to reduce the white noise in the front - end
摘要為了提高噪聲環境下說話人識別系統的識別性能,將基於聽覺掩蔽效應的語音增強技術作為預處理器,對語音信號首先進行降噪處理,提高輸入信號的信噪比。
