Overlapping speech is responsible for a certain amount of errors produced by tandard speaker diarization systems in meeting environment. We are investigating a set of prosody-based long-term features as a potential complement to our overlap detection system relying on short-term spectral parameters. The most relevant features are selected in a two-step process. They are firstly evaluated and sorted according to mRMR criterion and then the optimal number is determined by iterative wrapper approa...
