Abstract: A hearing aid includes an input providing an input signal representing sound in an environment, the input signal including no speech signal, or one or more speech signals from one or more speech sound sources and additional signal components, termed noise signal, from one or more other sound sources, an own voice detector, a voice activity detector, and a talker extraction unit to determine and/or receive one or more speech signals as separated one or more speech signals from speech sound sources other than the hearing aid user and to detect the speech signal originating from the voice of the user. The talker extraction unit provides separate signals, each including, or indicating presence of, one of the one or more speech signals. A noise reduction system determines speech overlap and/or gap between the speech signal originating from the user's voice and each of the separated one or more speech signals.

Abstract: Disclosed herein are embodiments of a method performed by a hearing aid and a hearing aid. An acoustical model can be used to generate first values (hk) for the multiple frequency channels based on first parameters (G, A, l); and a statistical model can be configured to generate second values (rk) for the multiple frequency channels based on values of second parameters (s1, s2, . . . , sn) and a set of basis vectors (u1, u2, . . . , un). An optimizer can be configured to obtain an optimized set of parameter values, wherein the optimized set of parameter values can be obtained by minimizing a difference between the first sound pressure levels (robs) and a combination of the first values (rk) and the second values (hk).

Abstract: A hearing aid microphone system includes M microphones providing corresponding electric input signals. Environmental sound at a given microphone includes a target sound signal propagated via an acoustic propagation channel from a direction to or a location of a target sound source to the microphone, and possible additive noise signals. The acoustic propagation channel is modeled. The hearing aid system includes: a processor connected to the microphones, and a database Θ having a multitude of dictionaries Δp, p=1, . . . , P, where p is a person index, of vectors, termed ATF-vectors, whose elements ATFm, m=1, . . . , M, are frequency dependent acoustic transfer functions representing direction- or location-dependent, and frequency dependent propagation of sound. The processor is configured to, at least in a learning mode of operation, determine personalized ATF-vectors based on the multitude of dictionaries Δp, the electric input signals, and the model of the acoustic propagation channels.
