In this paper, we present a new approach to enhance noisy speech based on an environmental model incorporating the phase between noise and clean speech (often called phase-sensitive model) in log power spectral domain. Some previous phase-sensitive methods normally assume the phase factor to be a random variable or set it heuristically. In this work, we assume phase to be an unknown parameter that...
Many cochlear implant (CI) users are able to understand speech in quiet listening conditions, however, CI users' speech recognition deteriorates rapidly as the level of background noise increases. To make CI more applicable in reallife environments, noise reduction is needed in CI processor. Recently, we presented a psychoacoustically-motivated adaptive beta-order generalized spectral subtraction...
