Abstract
It is possible to identify a hearing apparatus wearer's own voice for signal processing in a hearing apparatus. In a method for estimating one's own voice component, a first microphone is positioned outside the auditory canal and a second microphone is positioned within the auditory canal. The microphone signals are segmented into a number of regions in a time-frequency plane. A region phase difference and a region level difference are then determined respectively for each of the regions from one of the two t-f signals compared with the other of the two t-f signals. All the number of regions of the time-frequency plane, the region phase difference of which corresponds generally to the estimated phase difference and the region level difference of which corresponds generally to the estimated level difference, are then grouped, the signal components of the group serving as an estimation of the voice component.
