Abstract
The application relates to a hearing device, e.g. a hearing aid, adapted for being worn by a user and for receiving sound from the environment of the user to process the sound with a view to the user's intelligibility of speech in said sound, wherein an estimate of the user's intelligibility of speech in said sound being defined by a speech intelligibility measure I of said sound at a current point in time t, the hearing device comprising a) an input unit for providing a number of electric input signals y, each representing said sound in the environment of the user, b) a signal processor for processing said number of electric input signals y according to a configurable parameter setting Θ of one or more processing algorithms, which when applied to said number of electric input signals y provides a processed signal y(Θ) in dependence thereof, the signal processor being configured to provide a resulting signal y, c) a controller configured to control the processor to provide said resulting signal yat a current point in time t in dependence of c1) a parameter set Φ defining a hearing profile of the user, c2) said electric input signal(s) y or characteristics extracted from said electric input signal(s), e.g. a noise covariance matrix Cand/or covariance matrix Cof noisy signals, c3) a current value I(y) of said speech intelligibility measure I for at least one of said electric input signals y, c4) a desired value Ides of said speech intelligibility measure, c5) a first parameter setting Θ1 of said one or more processing algorithms, c6) a current value I(y(Θ1)) of said speech intelligibility measure I for a first processed signal y(Θ1) based on said first parameter setting Θ1, and c7) a second parameter setting Θ' of said one or more processing algorithms, which, when applied to said number of electric input signals y, provides a second processed signal y(Θ′) exhibiting said desired value Iof said speech intelligibility measure. The application further relates to a method of operating a hearing device. The invention may e.g. be used in hearing aid systems, or other portable audio processing systems.
