Abstract: A method operates a hearing device system which has a hearing aid and a peripheral device which provides a voice-controlled digital assistant. A microphone signal from the hearing aid is examined for own voice components of the wearer of the hearing aid. If own voice components are detected by the hearing aid the microphone signal is examined for a pre-defined activation command for the digital assistant. If the activation command is recognized, a portion of the microphone signal representing the activation command and a subsequent speech sequence is processed by the hearing aid for a speech recognizer of the digital assistant using an algorithm. The processed portion of the microphone signal is transmitted to the peripheral device.

Abstract: A method operates a hearing aid system having a hearing instrument. An electro-acoustic input transducer of the hearing instrument generates an input signal from an acoustic signal from the environment, and an output signal is generated from the input signal by a signal processor. An output acoustic signal is generated from the output signal by an electro-acoustic output transducer of the hearing instrument. For at least one sub-process of the signal processing an artificial neural network is used which is implemented in the hearing instrument. A topology of the artificial neural network is defined and/or weights between individual neurons of the artificial neural network are selected according to an operation to be performed in the sub-process and/or according to an ambient situation and/or according to a user input by a user of the hearing aid system.

Abstract: A hearing apparatus has a microphone for converting ambient sounds into a microphone signal, a signal processor for processing the microphone signal and an output transducer for outputting an output signal. A characteristic voice measure is ascertained for a voice component in the ambient sounds, and a supplementary measure characteristic of an activity of the wearer of the hearing apparatus is ascertained. Subsequently, an evaluated correlation between the voice measure and the supplementary measure is used to increase a probability value for the presence of a communication situation between the user and a third party if the voice measure and the supplementary measure, under at least one prescribed criterion, assume a value representative of the presence of the voice component and of the activity of the wearer. The probability value forms the basis for altering a signal processing algorithm that is executed to process the microphone signal.

Abstract: A hearing aid has at least two input transducers and at least one output transducer. The input transducers generate an input signal from a sound signal from the surroundings. At least two directional signals with different directional characteristics are formed from the input signals and the directional signals are examined for the presence of a useful signal. A first weighting factor is assigned to the directional signal with the largest signal component of the useful signal and a second weighting factor is assigned to the other directional signals. The directional signals are multiplied by the respectively assigned weighting factor, and an output signal is then formed from the multiplication result. The output signal is converted into a sound signal by the output transducer.

Abstract: A hearing system includes first and second hearing devices. A first reference signal and a first auxiliary signal are generated for the first hearing device from an ambient sound by a first reference microphone and a first auxiliary microphone, respectively. A first pre-processed signal is generated by direction-sensitive pre-processing the reference and auxiliary signals. The first pre-processed signal shows a maximal attenuation for a generic sound signal originating from an angular range of [+90°, +270°] with respect to a first frontal direction, and a first head-related transfer function for the first hearing device is provided. A second pre-processed signal is generated for the second hearing device by its microphones which is representative of the ambient sound, and a second position-related transfer function is provided for the second hearing device. The pre-processed signals are subjected to a direction-sensitive signal processing task using the first and second head-related transfer functions.

Abstract: A method for directional signal processing for a hearing aid. First and second input transducers generate first and second input signals from an ambient acoustic signal. A forward signal and a backward signal are generated from the first and second input signals and a first directional parameter is determined as a linear factor of a linear combination of the forward and backward signals. The first directional signal has a maximum attenuation in a first direction. A correction parameter is ascertained such that a second directional signal has a defined relative attenuation in the first direction. The second directional signal is generated from the forward signal and the backward signal with the first directional parameter and the correction parameter or with the first directional signal and the omnidirectional signal based on the correction parameter. An output signal of the hearing aid is generated based on the second directional signal.

Abstract: A method operates a hearing device. A first input signal is generated by a first input transducer of the hearing device from an ambient sound signal. An external input transducer outside of the hearing device generates an external input signal from the ambient sound signal. A relative transfer function from the external input transducer to the hearing device with respect to a target signal source is ascertained based on the first input signal and/or external input signal. The external input signal is filtered by the relative transfer function, thereby generating an estimated target signal. Noise suppression takes place in the hearing device based on the estimated target signal.

Abstract: A method improves a picked-up signal in a hearing system. The hearing system has at least one hearing device, particularly a hearing aid. The hearing aid device has an associated first directional microphone that has an adjustable first directional characteristic with a preferential direction. The first directional microphone converts sound into a first signal that is adopted in the picked-up signal. A speech activity of a user of the hearing system is monitored, and recognition of a speech activity of the user prompts the preferential direction of the first directional characteristic to be adjusted in comparison with a frontal direction of the user such that the sound sensitivity of the first directional microphone undergoes attenuation in the frontal direction.

Abstract: A method for operating a hearing device having an input transducer, a signal processing device and an output transducer includes using the input transducer to generate an input signal. The signal processing device has a quality checking unit used to take the input signal as a basis for determining a measure of a signal quality. The quality checking unit is configured for two operating modes, specifically a first operating mode and a second operating mode. The signal processing device has an own voice checking unit used to take the input signal as a basis for determining an activity of an own voice. The quality checking unit is operated in the first operating mode if no activity of an own voice is determined and in the second operating mode if an activity of the own voice is determined. A hearing device and a computer program product perform the method.
