BUT2012 Approaches for Spoken Web Search - MediaEval 2012

We submitted two approaches as the required runs: Acoustic Keyword Spotting as the primary one (AKWS) and Dynamic Time Wrapping as the secondary one (DTW) for the Spoken Web Search task. We aimed at building a simple phone based language-dependent system. We experimented with universal context bottle-neck neural network classifier with 3-state phone posterior features or bottle-neck features.
