This is the system description corresponding to the systems developed by the BUT team for The Third DIHARD Speech Diarization Challenge. The systems for both tracks consist of a DOVERlap fusion of an end-to-end NN system with xvector based clustering systems in the form of spectral clustering and VBx. Given that the x-vector clustering systems do not provide overlapping speakers, overlapped speech is detected by a TasNet-based detector before the final fusion with the end-to-end approach.
