摘要： Disclosed is a method and a hearing device for enhancing speech intelligibility, the hearing device comprising an input transducer for providing an input signal comprising a speech signal and a noise signal; a processing unit configured for processing the input signal; an acoustic output transducer coupled to an output of the processing unit for conversion of an output signal form the processing unit into an audio output signal; wherein the processing unit is configured for performing a codebook based approach processing on the input signal, where the processing unit is configured for determining one or more parameters of the input signal based on the codebook based approach processing, where the processing unit is configured for performing a Kalman filtering of the input signal using the determined one or more parameters, where the processing unit is configured to provide that the output signal is speech intelligibility enhanced due to the Kalman filtering.
