Subtitling the Trial of the Century: The People v. O.J. Simpson

This dissertation compares the performance of Neural Machine Translation (NMT) and Artificial Intelligence (AI) tools in the context of Audiovisual Translation (AVT), specifically focusing on a Post-Editing (PE) analysis. The study is based on the documentary series "OJ25" produced by CourtTV, which covers the 1995 trial against O.J. Simpson. The project involved post-editing the NMT and AI-translated subtitles of selected interrogations and the full final episode, using OOONA for the spotting phase and Trados Studio for the PE process. The analysis is divided into qualitative and quantitative sections. The Translation Quality Assessment (TQA) employs the FAR methodology to categorize errors produced by the two tools. The quantitative analysis calculates the Translation Error Rate plus (TERp) to measure the post-editing effort for both NMT and AI. The findings highlight the distinct error patterns generated by the different systems, providing a measurable assessment of the required PE effort for each tool, contributing to the understanding of MT efficacy in specialized legal AVT.
