  We introduce Seshat, a new, simple and open-source software to efficiently
manage annotations of speech corpora. The Seshat software allows users to
easily customise and manage annotations of large audio corpora while ensuring
compliance with the formatting and naming conventions of the annotated output
files. In addition, it includes procedures for checking the content of
annotations following specific rules that can be implemented in personalised
parsers. Finally, we propose a double-annotation mode, for which Seshat
computes automatically an associated inter-annotator agreement with the
$\gamma$ measure taking into account the categorisation and segmentation
discrepancies.
