Bird sound detection from real-field recordings is essential for identifying bird species in bioacoustic monitoring. Variations in the recording devices, environmental conditions, and the presence of vocalizations from other animals make the bird sound detection very challenging. In order to overcome these challenges, we propose an unsupervised algorithm comprising two main stages. In the first stage,...
The problem of detecting overlapped speech in stereo recordings using close-talk microphones is important for a variety of applications including the identification of back-channels, interruptions etc. in a dyadic or multi-party interactions. For detecting overlapped speech, we propose a feature derived using the spectral similarity of two channels over a range of acoustic frames. During overlapped...
