With a cochlear implant deaf people are able to understand speech under good listening conditions. Problems occur in adverse conditions, e.g. in reverberant and/or noisy environments. The speech intelligibility was examined in noisy situations for some persons using their implant system with and without the internal noise suppression. Experiments were carried out to improve the intelligibility of noisy speech using a single-channel noise suppression technique. This was realized by preprocessing i.e. by applying the resynthesized speech signal to the cochlear implant system.
