1. A method for using a single integrated hearing aid by a hearing aid user wearing the single integrated hearing aid, comprising: a processor in the single integrated hearing aid to generate a first signal representing sound received by the single integrated hearing aid; the processor processing the first signal to provide a noise reduced signal representative of speech by the single integrated hearing aid user and a noise signal; the processor processing the noise signal to determine at least a first and a second noise feature; the processor processing the noise reduced signal to determine a speech feature; the processor estimating an equal error rate classification threshold size based on the at least first and second noise feature; the processor processing information from a database of the single integrated hearing aid user's speech, the speech feature and the classification threshold to recognize the noise reduced signal as the single integrated hearing aid user's own voice; and the processor changing a processing setting when the processor recognizes the noise reduced signal as the hearing aid user's own voice to modify a beamforming setting in the single integrated hearing aid to reduce a distortion of the hearing aid user's voice in the single integrated hearing aid.
