Confidence based acoustic event detection

Xia, X., Togneri, R., Sohel, F. and Huang, D. (2018) Confidence based acoustic event detection. In: 2018 IEEE International Conference on Acoustics, Speech and Signal Processing, 15 - 20 April 2018, Calgary, Alberta, Canada



Acoustic event detection, the determination of the acoustic event type and the localisation of the event, has been widely applied in many real-world applications. Many works adopt the multi-label classification technique to perform the polyphonic acoustic event detection with a global threshold to detect the active acoustic events. However, the manually labeled boundaries are error-prone and cannot always be accurate, especially when the frame length is too short to be accurately labeled by human annotators. To deal with this, a confidence is assigned to each frame and acoustic event detection is performed using a multi-variable regression approach in this paper. Experimental results on the latest TUT sound event 2017 database of polyphonic events demonstrate the superior performance of the proposed approach compared to the multi-label classification based AED method.
