Hearing device comprising speech intelligibility estimator

The present application discloses a hearing device comprising a speech intelligibility estimator, the hearing device comprising: an input unit configured to provide at least one time-varying electrical input signal representative of sound, the at least one electrical input signal comprising a target signal component, the target signal component originating from a target sound source; a signal processing unit for processing at least one electrical input signal and providing a processed signal; an output unit for generating an output stimulus configured to be perceivable as a sound by a user based on the processed signal from the signal processing unit; a speech presence probability prediction unit for repeatedly providing a measure of a predicted speech presence probability of at least one electrical input signal or a signal derived therefrom; a speech intelligibility prediction unit for repeatedly providing a predicted current measure of speech intelligibility of the at least one electrical input signal or a
