In this paper, we propose a multi-modal voice activity detection system
(VAD) that uses audio and visual information. In multi-modal (speech)
signal processing, there are two methods for fusing the audio and the
visual information: concatenating the audio and visual features, and
employing audio-only and visual-only classifiers, then fusing the
unimodal decisions. We investigate the effectiveness of decision fusion
given by the results from AdaBoost. AdaBoost is one of the machine
learning method. By using AdaBoost, the effective classifier is
constructed by combining weak classifiers. It classifies input data
into two classes based on the weighted results from weak classifiers.
In proposed method, this fusion scheme is applied to decision fusion of
multi-modal VAD. Experimental results show proposed method to
generally be more effective. |
