Papercup
PaidEnterprise AI dubbing that faithfully reproduces a speaker's tone, emotion, and pace, now integrated into RWS's language services.
What is Papercup?
Papercup was a pioneering London-based AI dubbing company, founded in 2017 and known for its unique ability to reproduce a speaker's tone, pace, and emotion faithfully across translated audio. It served major media clients including Sky News and Bloomberg, generating over 1 billion dubbed video views. In June 2025, RWS, a global content solutions company, acquired Papercup's technology IP and integrated it into their enterprise language services stack alongside Language Weaver and the Trados platform. The combined solution now offers enterprise-grade AI dubbing with a human-in-the-loop approach: Papercup's AI voice synthesis handles speed and scale, while RWS's 1,800 in-house linguists and 40,000+ global language experts fine-tune tone, pacing, and brand accuracy. This hybrid approach is ideal for enterprise clients localizing corporate communications, training, and media content who need both the speed of AI and the quality assurance of human review.

How to Use Papercup
✅ Best For
- Enterprise brands and media companies that require high-fidelity AI dubbing where the original speaker's emotional tone and pace are critical to the audience experience, not just linguistic accuracy.
- Corporate communications and L&D teams at global organizations who need to localize executive communications, training content, and company-wide videos into multiple languages at scale with quality assurance.
- Broadcasters, streaming platforms, and documentary producers who need AI dubbing quality that is comparable to human voice actors but at a fraction of the traditional cost and turnaround time.
❌ Not For
- Individual creators or small businesses who need self-serve dubbing tools with instant access, as Papercup via RWS operates as an enterprise service with consultation and custom pricing rather than a DIY platform.
- Users who need video generation, avatar creation, or real-time live translation, as Papercup specializes exclusively in pre-recorded video and audio dubbing and localization.
