| Abstract | This paper proposes an approach to frame-level speech ac-tivity detection based on the extended metaphor of an eco-nomics marketplace. As in a real marketplace, the simulatedmarketplace encourages features to specialize. Features thatmight not have impressive average performance across the en-tire data set might nonetheless perform very well on a subsetof the data, and the marketplace capitalizes on this special-ization by consulting the features only when their expertiseis relevant. On an experimental data set, we show that theframework is able to effectively utilize the expertise of a set |
