Abstract: A system and method to perform an estimation of a location of an active speaker in real time includes designating a microphone of an array of microphones as a reference microphone. The method includes storing a relative transfer function (RTF) for each microphone of the array of microphones other than the reference microphone associated with each potential location among potential locations as a set of stored RTFs, and obtaining a voice sample of the active speaker and obtaining a speaker RTF for each microphone of the array of microphones other than the reference microphone. The method also includes performing an RTF projection of the speaker RTF for each microphone on the set of stored RTFs, and determining one of the potential locations as the location of the active speaker based on the performing the RTF projection.

Abstract: Provided are an electronic device and a reverberation removal method therefor. The reverberation removal method for an electronic device comprises: a plurality of microphone units for receiving a user's voice; a reverberation removal unit removing a reverberation component of the user's voice received from the plurality of microphone units so as to acquire an original component of the user's voice; a reverberation information acquisition unit for acquiring information on the intensity of the reverberation component of the user's voice; and a post-processing unit for additionally removing a reverberation component from the original component acquired from the reverberation removal unit on the basis of the information on the intensity of the reverberation component.
