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.
