# Intro

The Callmark web interface offers an interactive user interface to simplify the annotation process for both human speech and animal vocalizations. It is the frontend part of a full-stack application which was created as part of a [NCCR](https://www.liri.uzh.ch/en/services/collab/nccr.html) research project. It was contributed by Alon Cohen, Nianlong Gu and Maris Basha.
