Patent number: 11676621Abstract: A hearing device includes: an input module for provision of a first input signal; a processor configured to provide an electrical output signal based on the first input signal; a receiver configured to provide an audio output signal; and a controller comprising a speech intelligibility estimator configured to determine a speech intelligibility indicator indicative of speech intelligibility based on the first input signal, wherein the controller is configured to control the processor based on the speech intelligibility indicator; wherein the speech intelligibility estimator comprises a decomposition module configured to decompose the first input signal into a first representation of the first input signal in a frequency domain, wherein the first representation comprises one or more elements representative of the first input signal; and wherein the decomposition module comprises one or more characterization blocks for characterizing the one or more elements of the first representation in the frequency domain.Type: GrantFiled: June 3, 2021Date of Patent: June 13, 2023Assignee: GN HEARING A/SInventors: Charlotte Sørensen, Jesper B. Boldt, Angeliki Xenaki, Mathew Shaji Kavalekalam, Mads G Christensen
