We propose a method for audio event detection in video streams from news Apart from detecting speech, which is obviously the major class in such content, the proposed method detects five non-speech audio classes The major difficulty of the particular task lies in the fact that most of the non-speech audio events are actually background sounds, with speech as the primary sound We have adopted a set of 21 statistics computed on a mid-term basis over 7 audio features A variation of the One Vs All classification architecture has been adopted and each binary classification problem is modeled using a separate probabilistic Support Vector Machine Experiments have shown that the proposed method can achieve high precision rates for most of the audio events of interest.
