An investigation of temporal feature integration for a low-latency classification with application to speech/music/mix classification

In this study, we propose several methodologies for the use of feature integration and evaluate them in a low-latency classification framework. These general methodologies are based on three key aspects that will be assessed in this study: the selection of the features which have to be temporally integrated, the choice of the integration techniques, i.e. how the temporal information is extracted, and the size of the integration window. The experiments carried out for the speech/music/mix classification task show that the different methodologies have a significant impact on the global performance. Compared to the state of the art procedures, the methodologies we proposed achieved good performance, even with the low-latency constraints.
