Method for operating a hearing instrument and hearing system containing a hearing instrument

A method for operating a hearing instrument that is worn in or at an ear of a user, which comprises the following steps of:

• capturing a sound signal from an environment of the hearing instrument;
• processing a captured sound signal in dependence of a set of signal processing parameters;
• analyzing the captured sound signal to recognize own-voice intervals, in which the user speaks;
• analyzing the captured sound signal for at least one acoustic feature of an own voice of the user and/or analyzing a signal of at least one bio sensor, the at least one bio sensor measuring at least one non-acoustic vital function of the user;
• testing the at least one acoustic feature of the own voice of the user and/or the at least one non-acoustic vital function of the user, with respect to a predefined criterion;
• adapting a value of at least one of the signal processing parameters, within the own-voice intervals, to change an emotional state if the predefined criterion is fulfilled, wherein the predefined criterion having a desired value of the at least one acoustic feature of the own voice of the user and/or the at least one vital function of the user;
• performing the testing step to include a determination of a deviation of the at least one acoustic feature of the own voice of the user and/or the at least one vital function of the user with respect to the desired value;
• adapting a value of at least one of the signal processing parameters so that the deviation is reduced;
• and
• outputting a processed sound signal to the user.

A hearing system with a hearing instrument to be worn in or at an ear of a user, the hearing instrument comprising:

• an input transducer disposed to capture a sound signal from an environment of the hearing instrument;
• a signal processor disposed to process a captured sound signal in dependence of a set of signal processing parameters;
• an output transducer disposed to emit a processed sound signal into the ear of the user;
• a voice recognition unit configured to analyze the captured sound signal to recognize own-voice intervals, in which the user speaks;
• at least one bio sensor measuring at least one non-acoustic vital function of the user;
• an analysis unit configured to analyze the captured sound signal for at least one acoustic feature of an own voice of the user and/or to analyze a signal of said at least one bio sensor;
• a controller configured to determine, from the at least one acoustic feature of the own voice of the user and/or the at least one non-acoustic vital function of the user, a measure of an emotional state of the user, wherein the controller is configured to:
• test the measure of the emotional state with respect to a predefined criterion;
• and
• adapt a value of at least one of the signal processing parameters, within the own-voice intervals, to change the emotional state if the predefined criterion is fulfilled, wherein the predefined criterion includes a desired value of the measure of the emotional state;
• determine a deviation of the measure of the emotional state with respect to the desired value;
• and
• adapt the value of the at least one signal processing parameter so that the deviation is reduced.
