摘要

A method of identifying the user's own voice in a hearing instrument system and a hearing instrument system for performing such method is provided wherein a direct-to-reverberant ratio (DtoR) between the signal energy of a direct sound part (1a; 1b) and that of a reverberant sound part (2a, 3a; 2b, 3b) of at least a part of a recorded sound is used to assess wether the sound originates from the users own voice or not. This allows a very reliable detection of the users own voice in a hearing-instrument system. Further, a hearing-instrument system comprising an own-voice detector configured to perform such method is provided.
