Pitch Based Sound Classification [PDF]
2006 IEEE International Conference on Acoustics Speed and Signal Processing Proceedings, 2006 A sound classification model is presented that can classify signals into music, noise and speech. The model extracts the pitch of the signal using the harmonic product spectrum. Based on the pitch estimate and a pitch error measure, fea tures are created and used in a probabilistic model with soft max output function.

Automatic fish sounds classification [PDF]
Journal of the Acoustical Society of America, 2016 The context of this work is environmental monitoring. Specifically, we focus on acoustic systems for monitoring fish populations. By investigating the recorded sounds of fishes, it is possible to monitor the spatial and temporal evolution of fish populations. The aim of this work is to present an automatic fish sounds classification system.
