Abstract: A hearing aid includes a) at least one input unit for providing a time-frequency representation Y(k,n) of an electric input signal representing sound consisting of target speech and noise signal components, where k and n are frequency band and time frame indices, respectively, b) a noise reduction system configured to b1) determine an a posteriori signal to noise ratio estimate γ(k,n) of the electric input signal, and to b2) determine an a priori signal to noise signal ratio estimate ζ(k,n) of the electric input signal from the a posteriori signal to noise ratio estimate γ(k,n) based on a recursive algorithm providing non-linear smoothing. The a posteriori signal to noise ratio estimate of said electric input signal is provided as a mixture of first and second different a posteriori signal to noise ratio estimates. The invention may be used in audio processing devices, such as hearing aids, headsets, etc.

Abstract: A hearing system comprises a hearing device, e.g. a hearing aid, configured to be worn by a particular user at or in an ear, or to be fully or partially implanted in the head at an ear of the user. The hearing device comprises at least one microphone for converting a sound in the environment of the hearing device to an electric input signal. The hearing system, e.g. the hearing device, comprises a processor comprising an own voice analyzer configured to characterize the voice of a person presently wearing the hearing device based at least partly on said electric input signal, and to provide characteristics of said person's voice, and an own voice acoustic channel analyzer for estimating characteristics of an acoustic channel from the mouth of the person presently wearing the hearing device to the at least one microphone based at least partly on said electric input signal, and to provide characteristics of said acoustic channel of said person. The hearing system further comprises a user identification unit configured to provide a user identification signal indicating whether or not, or with what probability, the person currently wearing the hearing device is said particular user in dependence of said characteristics of said person's voice and said characteristics of said acoustic channel of said person.
