The exceptions tend to be talks that are released on a video streaming platform such as YouTube, where there is often the utility to have the service automatically transcribe and show subtitles as the video streams. While an increasing number of conferences are able to release recordings of the presentations, few if any seemed to also release subtitle files to accompany the videos. This didn’t seem cool to us so we set out to see what we could do to make security conference videos more accessible to those who are harder of hearing or who just prefer having subtitles while they watch.Įvery year there are thousands of talks given across the many security conferences that take place around the world. Looking through our multi-terabyte conference video archive from conferences around the world we found the same to be true for all the conference videos we had: not a single. To our surprise even though we had spent quite a lot of money on buying licenses for the professionally produced Blackhat videos, none of them came with subtitle files. Decipher’s Fahmida Rashid asked a great question in the Duo Labs Slack channel, whether there were subtitle files available for some Blackhat US 2019 conference videos that we were watching as part of a broader research project. My intention being that by lowering the barrier to creation of subtitle files we increase the number of them that will be available for security content.īefore we dig into the specifics of the approach that was taken it is worth noting where the inspiration for this work came from. My hope is that by raising the subject for discussion, sharing the approach to the automatic creation of subtitle files, and releasing the tooling built to do all of this as open source software we will better enable the community to easily and cheaply create subtitle files. As part of this broader goal, I wanted to share some work done recently that helps make videos of security conference presentations accessible to more people through the efficient transcription of the words spoken and the creation of subtitle files to accompany the video file. Making high quality security information as widely available as possible has been a primary goal of Duo Labs from its inception and this goes not only for our own research but also the wealth of high quality work shared by other groups and individuals.
