Sony Interactive Entertainment used machine learning-based voice recognition software to automatically synchronize multilingual subtitles to dialogue in Marvel's Spider-Man 2, significantly reducing the time required for the localization subtitling process.

Disclosed in Sony's 2024 Corporate Report, the company applied voice recognition software to certain languages during the production of Marvel's Spider-Man 2 (released October 2023). The system matched subtitle text to each character's spoken lines automatically, which Sony described as 'significantly shortening the subtitling process.' Spider-Man 2 launched with text support for 27 languages, with 12 fully dubbed. Sony framed the practice as part of its strategy to deliver IP 'rapidly and at low cost to a broader range of fans.' Sony's 2025 corporate report additionally referenced machine-learning tools applied to dialogue subtitling as part of its broader AI deployment across PlayStation studios.
