Robust Speaker Identification for Meetings: UPC CLEAR'07 Meeting Room Evaluation System

In this paper, the authors describe the UPC speaker identification system submitted to the CLEAR'07 (Classification of Events, Activities and Relationships) evaluation. Firstly, the UPC single distant microphone identification system is described. Then the use of combined microphone inputs in two different approaches is also considered. The first approach combines signals from several microphones to obtain a single enhanced signal by means a delay and sum algorithm. The second one fuses the decision of several single distant microphone systems. In our experiments, the latter approach has provided the best results for this task.
