In this paper, we describe the " Query by Example Search on Speech Task " (QUESST), held as part of the MediaEval 2015 evaluation campaign. As in previous years, the proposed task requires performing language-independent audio search in a low resource scenario. This year, the task has been designed to get as close as possible to a practical use case(More)
This study presents an approach to the task of automatically classifying and detecting speaking styles. The detection of speaking styles is useful for the segmentation of multimedia data into consistent parts and has important applications , such as identifying speech segments to train acoustic models for speech recognition. In this work the database(More)
