A method for operating a hearing instrument that is worn in or at the ear of a user, comprising the following steps: - capturing a sound signal from an environment of the hearing instrument; - analyzing the captured sound signal to recognize own-voice intervals, in which the user speaks, and foreign-voice intervals, in which at least one different speaker speaks; - determining, from the recognized own-voice intervals and foreign-voice intervals, at least one turn-taking feature (T TU /T TS, h LU /h TU, h OU /h TU); - analyzing, during recognized own-voice intervals, the captured sound signal for at least one of the following acoustic features of the own voice of the user: - the voice level; - the formant frequencies; - the pitch frequency; - the frequency distribution of voice; and - the speed of speech, - analyzing the captured sound signal for at least one of the following environmental acoustic features: - the sound level of the captured sound signal; - the signal-to-noise ratio; - the reverberation time; - the number of different speakers; and - the direction of the at least one different speaker; characterized in - deriving from the at least one turn-taking feature (T TU /T TS, h LU /h TU, h OU /h TU) a measure of the sound perception by the user; - testing the measure of the sound perception with respect to a predefined criterion indicative of a poor sound perception; and - taking a predefined action for improving the sound perception if said criterion is fulfilled, - wherein the measure of the sound perception is derived from a combination of - the at least one turn-taking feature; - the at least one acoustic feature of the own voice of the user; and - the at least one environmental acoustic feature; and - wherein said action for improving the sound perception comprises automatically altering at least one parameter of a signal processing of the hearing instrument such that the noise reduction and/or the directionality are increased. - capturing a sound signal from an environment of the hearing instrument; - analyzing the captured sound signal to recognize own-voice intervals, in which the user speaks, and foreign-voice intervals, in which at least one different speaker speaks; - determining, from the recognized own-voice intervals and foreign-voice intervals, at least one turn-taking feature (T TU /T TS, h LU /h TU, h OU /h TU); - analyzing, during recognized own-voice intervals, the captured sound signal for at least one of the following acoustic features of the own voice of the user: - the voice level; - the formant frequencies; - the pitch frequency; - the frequency distribution of voice; and - the speed of speech, - the voice level; - the formant frequencies; - the pitch frequency; - the frequency distribution of voice; and - the speed of speech, - analyzing the captured sound signal for at least one of the following environmental acoustic features: - the sound level of the captured sound signal; - the signal-to-noise ratio; - the reverberation time; - the number of different speakers; and - the direction of the at least one different speaker; characterized in - the sound level of the captured sound signal; - the signal-to-noise ratio; - the reverberation time; - the number of different speakers; and - the direction of the at least one different speaker; - deriving from the at least one turn-taking feature (T TU /T TS, h LU /h TU, h OU /h TU) a measure of the sound perception by the user; - testing the measure of the sound perception with respect to a predefined criterion indicative of a poor sound perception; and - taking a predefined action for improving the sound perception if said criterion is fulfilled, - wherein the measure of the sound perception is derived from a combination of - the at least one turn-taking feature; - the at least one acoustic feature of the own voice of the user; and - the at least one environmental acoustic feature; and - the at least one turn-taking feature; - the at least one acoustic feature of the own voice of the user; and - the at least one environmental acoustic feature; and - wherein said action for improving the sound perception comprises automatically altering at least one parameter of a signal processing of the hearing instrument such that the noise reduction and/or the directionality are increased.
