Towards Automatic Subtitling: Assessing the Quality of Old and New Resources

Abstract

Growing needs in localising multimedia content for global audiences have resulted in Neural Machine Translation (NMT) gradually becoming an established practice in the field of subtitling in order to reduce costs and turn-around times. Contrary to text translation, subtitling is subject to spatial and temporal constraints, which greatly increase the post-processing effort required to restore the NMT output to a proper subtitle format. In our previous work (Karakanta, Negri, and Turchi 2019), we identified several missing elements in the corpora available for training NMT systems specifically tailored for subtitling. In this work, we compare the previously studied corpora with MuST-Cinema, a corpus enabling end-to-end speech to subtitles translation, in terms of the conformity to the constraints of: 1) length and reading speed; and 2) proper line breaks. We show that MuST-Cinema conforms to these constraints and discuss the recent progress the corpus has facilitated in end-to-end speech to subtitles translation.

“A Spanish version of EastEnders”: a reception study of a telenovela subtitled using MT

“…With the growing use of MT in subtitle production (Koponen et al 2020b;Karakanta et al 2022), it becomes essential to explore how viewers respond to MT and PE subtitles in contrast with HT subtitles. Ortiz Boix (2016) examined two conditions (HT and PE) for voice-over translation of wildlife documentaries.…”

“…given the appropriate quality conditions (Bywood, Georgakopoulou, and Etchegoyhen 2017;Matusov, Wilken, and Georgakopoulou 2019;Koponen et al 2020a ). Additionally, studies have explored subtitlers' satisfaction with PE (Koponen et al 2020b;Karakanta et al 2022). However, there is currently no research that looks at the impact of MT in the translation workflow on the viewer of audiovisual content.…”
