In this paper, we demonstrate a method for training speaker em-
bedding extractors using weak annotation. More specifically,
we are using the full VoxCeleb recordings and the name of the
celebrities appearing on each video without knowledge of the
time intervals the celebrities appear in the video. We show that
by combining a baseline speaker diarization algorithm that re-
quires no training or parameter tuning, a modified loss with aggregation over segments, and a two-stage training approach, we
are able to train a competitive ResNet-based embedding extractor. Finally, we experiment with two different aggregation functions and analyze their behaviour in terms of their gradients.
