plain X is a 4-in-1 solution for language adaptation. The software is an outcome of European HLT research and is by now in use as the major artificial-intelligence-powered human language pro-cessing platform at Deutsche Welle. plain X is a one-stop-shop for automated transcription, translation, subtitling and voice-over, with human correction options at all stages. We demonstrate how the platform works and show new features and developments of the platform in the framework of the SELMA project.
