When silence is gold
Résumé
Audiovisual source separation is a fascinating approach to source extraction. Several algorithms have already been proposed for extracting speech sources from au- dio mixtures by exploiting audiovisual coherence. One of the main property of speech signals is that they are highly non-stationary: there are periods during which speakers do not produce sounds. In this work, the audio- visual coherence is used to estimate such silent periods which are then useful to extract corresponding speech signals.
