An efficient spectral subtraction-based strategy for suppressing reverberation in cochlear implant devices
ISIC(2014)
Abstract
In this work, we develop a spectral subtraction strategy capable of suppressing late reflections. Late reflections are the most detrimental to speech intelligibility by cochlear implant listeners as reverberation increases. By tackling only the late part of reflections, it is shown that users of cochlear implant devices can recognize words at a level near that attained in quiet listening conditions even in extremely reverberant rooms.
