Podcasts and video podcasts have become essential in modern corporate communication – whether as thought leadership formats, internal knowledge sharing, or marketing tools. But reach is often limited to a single language market.
👉 The solution: AI-powered video translation. It enables companies to make podcasts accessible across multiple languages – while keeping the authenticity of the original speakers.
Podcasts are far more complex than short-form videos:
Long runtime: Many providers limit translations to 10–30 minutes. Podcasts often run 60–120 minutes or more.
Multiple speakers: Distinguishing and synchronizing several voices is crucial.
Authenticity: Voice tone, emotions, and emphasis must remain intact.
Data privacy: Content often contains internal strategies, sensitive interviews, or corporate insights.
Most standard AI dubbing providers struggle here, delivering generic and unnatural results.
Dubly.AI is a German AI company specialized in high-quality, realistic, and GDPR-compliant video translation. For podcasts and interviews, Dubly offers unique capabilities that other providers simply lack.
