We propose a framework of devices which are tailored for the individual needs of the impaired with severe hearing losses, allowing them to participate in most of today's life communication situations, overcoming many of the drawbacks inherent to conventional hearing aid devices. The communication system proposed in this article consists basically of three units: a set of wireless microphones with advanced noise reduction capabilities; a portable multichannel receiver unit with special speech feature enhancement functions to allow an optimal adaptation to the residual sensory hearing area; and a wireless, highly noise resistant coupling between speech processing unit and behind-the-ear (BTE)-hearing aids. We discuss several techniques of enhancing and transforming significant speech features in order to increase overall speech intelligibility.
