This paper documents the acoustic source tracking system developed by TUT for the 2006 CLEAR evaluation campaign. The described system performs 3-D single person tracking based on audio data received from multiple spatially separated microphone arrays. The evaluation focuses on meeting room domain.

The system consists of four distinct stages. First stage is time delay estimation (TDE) between microphone pairs inside each array. Based on the TDE, direction of arrival (DOA) vectors are calculated for each array using a confidence metric. Source localization is done by using a selected combination of DOA estimates. The location estimate is tracked using a particle filter to reduce noise. The system is capable of locating a speaker 72 % of the time with an average accuracy of 25 cm.
