Abstract

This work addresses the problem of automatic speaker localization and tracking in a real lecture scenario.Evaluation criteria recently adopted under CHIL and NIST benchmarking are outlined.Two speaker localization systems are described, which are based on the use of Cross-power Spectrum Phase analysis and of Global Coherence Field. Benchmarking results were obtained on a set of 13 lectures and showed an average RMS error of about 30 cm in the speaker localization.
