1. A hearing device comprising:
an input module for provision of a first input signal, the input module comprising a first microphone;
a processor configured to provide an electrical output signal based on the first input signal;
a receiver configured to provide an audio output signal based on the electrical output signal; and
a controller operatively connected to the input module, the controller comprising a speech intelligibility estimator configured to determine a speech intelligibility indicator indicative of speech intelligibility, wherein the controller is configured to control the processor based on the speech intelligibility indicator;
wherein the hearing device is configured to decompose the first input signal into a first representation of the first input signal based on one or more characterization blocks of a speech codebook, and/or based on one or more characterization blocks of a noise codebook, and wherein the hearing device is configured to determine a reference speech signal based on the first representation; and
wherein the speech intelligibility estimator comprises an objective intelligibility estimator, and wherein the objective intelligibility estimator is configured to use the reference speech signal that is determined based on the first representation decomposed from the first input signal.
