Abstract: A method operates a hearing system which has a hearing instrument worn in an ear. The method includes capturing a sound signal from an environment, processing the captured sound signal in dependence of a set of signal processing parameters, and outputting a processed sound signal to the user. The method further includes analyzing the captured sound signal to recognize own-voice intervals, in which the user speaks, analyzing the captured sound signal for an acoustic feature of the own voice of the user and/or analyzing a signal of a bio sensor. The bio sensor measures at least one non-acoustic vital function of the user and determines, from the acoustic feature and/or the non-acoustic vital function of the user, a measure of an emotional state of the user. A value of a signal processing parameter is adapted, within the own-voice intervals, to change the emotional state if a criterion is fulfilled.

Abstract: A method operates a hearing aid where a sound is recorded by a microphone. The sound is analyzed with respect to the correspondence thereof with the own voice of the hearing aid wearer and a characteristic value is produced, which indicates how strongly the sound corresponds with the own voice. The own voice is a sound type. The characteristic value is compared with a threshold value and, depending on whether the characteristic value lies above or below the threshold value, the sound is identified as the own voice. Depending on whether the sound has been identified as the own voice, the hearing aid is switched among a plurality operating modes. The method is characterized in that the threshold value is set in accordance with the user. Thus, an improved own-voice identification recognizer is formed, which distinguishes the own voice of the hearing aid wearer from another sound type.

Abstract: A hearing system has a hearing instrument that may be worn in or on a user's ear, and a peripheral device or a control program that may run on a data processing device. A microphone signal detected by the hearing instrument is examined for the user's own-voice components and is processed by a signal processor of the hearing instrument as a function of predetermined signal processing parameters. When own-voice components are detected, a first parameter set of the signal processing parameters is applied; when own-voice components are not detected, a second parameter set of the signal processing parameters is applied. The first parameter set may be modified by the user via the peripheral device or the control program in order to adapt the own-voice components contained in the microphone signal to a user-desired perception of the user's own voice.

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 for enhancing a signal directionality in a hearing instrument wherein first and second signals are generated by first and second input transducers that are spaced apart from one another. A first directional signal is derived from the first input signal and the second input signal by applying a second-to-first relative transfer function with respect to a first target angle to the second input signal. The second-to-first relative transfer function is a relative transfer function from the second input transducer to the first input transducer with respect to the first target angle. Similarly, a second directional signal is derived from the second input signal and the first input signal by applying a first-to-second relative transfer function with respect to a second target angle to the first input signal. An angle-enhanced signal is derived from the first directional signal and the second directional signal.

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.
