1. A method for operating a hearing aid, the method comprising:
providing an auditory canal microphone configured for capturing sound in the auditory canal of a wearer;
providing an own voice recognition unit configured for carrying out an adaptive own voice recognition;
capturing sound in the auditory canal by the auditory canal microphone;
outputting, by the auditory canal microphone, an auditory canal signal that corresponds to the sound in the auditory canal; and
controlling, by starting a training of the adaptive own voice recognition only based on the signal output by the auditory canal microphone, wherein the training is started automatically during a normal operation, and determining a convergence value which represents a measure or quality for recognizing the own voice by the own voice recognition, and admitting or omitting a further training depending on the convergence value and deducing the presence of the own voice based on the convergence value; and
processing, during the normal operation, the auditory canal signal and/or the surround signal by a control unit and outputting the processed signal to a receiver for compensating a hearing deficit of the wearer, wherein speech sequences and/or noise sequences defined in advance for the purposes of training the own voice recognition are not used during normal operation.
