With the ever-growing quantity of multimedia documents uploaded on the Web, automatic description of the audio content of videos can provide very useful information, to index, archive and search multimedia documents. Audio Event Detection (AED), aims to substantially enhance the access to audio in multimedia content. Preliminary experiments with a sound eects corpus showed good results for training models. However, the performance on the real data test set, where there are overlapping audio events and continuous background noise is lower. This work describes the AED framework and methodologies used to build 6 Audio Event detectors, based on statistical machine learning tools (Support Vector Machines). The detectors showed some improvements achieved by adding background noises to the training data, comprised of clean sound eects that are quite dier
