Papercup

Papercup is RWS's AI dubbing orchestration service for TV, film and digital video. It combines automated transcription, post-edited machine translation, licensed AI voices, voice cloning and prosody transfer with human linguists and audio engineers, aimed at studios, streamers and broadcasters localizing large catalogs.

Papercup is RWS's AI dubbing orchestration layer for film, television and digital video. It sits inside an existing media supply chain rather than acting as a standalone self-serve desktop tool, giving studios, streamers, broadcasters and media organizations a centralized place to manage multilingual video content across complex distribution environments. The pitch is catalog scale: localize far more titles per year, shorten the gap between release and international launch, and test new markets with AI-enabled workflows before committing to full production budgets. The workflow is deliberately hybrid. Context-aware transcription with automatic speaker detection builds a structured script, with expert review catching ASR errors. Machine translation is then post-edited by linguists who protect tone and cultural nuance. Voice selection draws on ethically sourced AI voices, and voice cloning can replicate the original speaker across languages and accents under licensing and compliance controls. The platform supports transcript and translation editing so teams can adjust timing, synchronization and lip sync. Its cross-lingual prosody transfer aims to carry pacing and emotional nuance between languages. Audio engineering and mixing close the loop, and finished audio exports into the client's preferred distribution platforms. Buyers are usually content operations leads rather than individual creators. RWS positions tiered strategies: premium titles can move through full production workflows with human dubbing and voice direction, while large back catalogs move through lower-cost AI paths. RWS backs the service with a network of more than 43,000 linguists, decades of localization experience and additional services such as subtitling and SDH, captioning and audio description. Compared with DIY dubbing apps, Papercup is a managed, governance-heavy option with a higher entry point; compared with traditional dubbing houses, its appeal is speed and per-title cost at catalog volume. Prices, SLAs and onboarding requirements are quoted per project, so the listing cannot publish rates. It is a poor fit for creators who want to upload a clip and pay by the minute. It is a reasonable fit for organizations that already run localization programs and want AI to absorb volume while humans guard the final mix.
