Abstract
Speech intelligibility is to be improved in hearing devices and in particular in hearing aids. A method for reconstructing a speech signal is therefore proposed, wherein a predefined amplitude spectrum of a speech component is stored. The amplitude spectrum of an input signal containing the speech signal is acquired. At least one matching portion and one non-matching portion of the predefined amplitude spectrum with respect to the amplitude spectrum of the input signal is detected. Finally the gain of the input signal in the non-matching portion of the amplitude spectrum is varied such that a closer match with the predefined amplitude spectrum is achieved compared to the original gain.
