This paper proposes a technique for determining the distance between a sound source and the microphones in an array. The proposed “Range-Finder” algorithm is robust in the presence of reverberation and, in contrast with previously published sourcelocalization techniques, does not require knowledge of the relative positions of the microphones. We discuss the factors affecting the accuracy of our...

In this paper, we propose a method for detecting the location of the speaker that is a target of automatic video filming in distance learning and lecture archive. It is required that a face of a speaking student is filmed in a lecture video. For this purpose, it is necessary to detect the location of a speaker. An acoustic sensor such as a microphone array is used widely to detect the location ...
