Multichannel Speech Enhancement in the Frequency Domain
Abstract
In this chapter, we study the multichannel speech enhancement problem in the frequency domain. By exploiting the structure of the speech subspace, we can easily estimate all convolved speech signals at the microphones with a simple complex filter. As a result, binaural noise reduction with this approach is straightforward since we can choose any two signals from the estimated convolved speech signals, which contain all the necessary spatial information for the localization of the desired source signal.
