The proposed noise reduction method is an improvement of the well-known spectral subtraction method which uses one SNR-depen-dent gain function to suppress ...
This paper describes a noise suppression algorithm based on spectral subtraction. The method employs a noise and speech-dependent gain function for each ...
In contrast, the gain function in Figure 5.9 is observed to be relatively smooth. The adaptive mean parameter calculated using (5.59) is shown in Figure 5.10.
In this paper we suggest a method which uses multiple spectral subtraction functions and two microphones, introducing only a short signal delay.
