掩蔽系数 meaning in Chinese

masking factor

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
然后求取每个小片段上的itd (到达双耳时间上的差异性)和iid (到达双耳强度上的差异性)值，经过实验证明某个片段上的itd值和iid值与该片段上的信噪能量比是单调递增关系，因此通过和域值的比较，得出掩蔽系数，来判断每个小片段具体是属于哪个声源。
