Papercup
Papercup translates and dubs video and audio with AI voices that aim to match a speaker's tone, pace, and emotion. The papercup.com site now routes to RWS AI dubbing services after RWS acquired Papercup's technology in June 2025, folding the stack into enterprise localization alongside Language Weaver and Trados.
Most AI dubbing tools sound flat or miss lip-sync timing. Papercup built synthetic voices plus editor tools for linguists to adjust pacing, and RWS keeps humans in the loop with 1,800 in-house linguists and 40,000 external language experts. Media customers such as Sky News and Bloomberg previously used Papercup dubbing for large-scale multilingual video reach.
Papercup fits enterprise teams localizing training libraries, corporate communications, and marketing video at volume. It helps broadcasters expanding news clips into multiple languages and regulated industries that need human review on dubbed safety or compliance content.
The product is sold as an enterprise RWS service rather than a self-serve app. Teams contact RWS through the papercup.com migration page for project pricing and hybrid AI plus human dubbing workflows.
