The demand for AI-powered video translation is rising fast. Many businesses are evaluating tools like ElevenLabs and Dubly.AI. But while ElevenLabs impresses with its audio generation, it falls short when it comes to professional dubbing. Dubly, on the other hand, offers a complete solution designed specifically for companies of all sizes – from SMBs to enterprises.
ElevenLabs is a U.S.-based provider focused on speech synthesis and voice cloning. It is widely known in the creator community for its natural-sounding voices.
High-quality text-to-speech audio generation
Flexible for podcasts, audiobooks, and creator projects
Innovative in voice cloning technology
❌ No Lip Sync – audio runs independently of video
❌ Inaccurate translations, often lacking context awareness
❌ Unnatural pacing and timing, voices don’t match visuals
❌ No glossary management for brand or technical terms
❌ Data processed on U.S. servers, not GDPR-compliant
For audio-only applications, ElevenLabs is a strong tool. For video dubbing, however, it lacks essential capabilities.
Dubly.AI is a German AI company headquartered in Leverkusen with an office in Frankfurt. Its clear focus: precise, secure, and highly realistic video translations.

For audio-only content, ElevenLabs is a solid choice.
For video dubbing, however, it lacks essential features – from translation quality and timing realism to Lip Sync and GDPR compliance.
👉 Dubly.AI is the only complete solution that provides businesses with professional, secure, and highly realistic video translation.
