FAQ: Translating Podcasts with AI
Which provider is best for podcast translation?
Dubly.AI is the only provider with multi-speaker support, unlimited length, and realistic lip sync.
Can I translate video podcasts too?
Yes. Dubly.AI supports video podcast translation with natural lip sync and voice cloning.
Is podcast translation with Dubly GDPR-compliant?
Yes. Dubly is 100% GDPR-compliant, with EU-based servers and enterprise-level contracts.
Why do other providers fail with long podcasts?
Most AI tools are built for short clips (10–30 min). Dubly.AI can handle multi-hour podcasts and interviews without issue.
Conclusion: Podcast Translation – Only Professional with Dubly
Many providers deliver functional but generic results. But podcast translation requires enterprise-level quality: multi-hour runtimes, multiple speakers, brand voice, and GDPR compliance.
👉 Dubly.AI is the only solution that combines all these capabilities in one platform.
What is the difference between Dubbing and Lip Sync?
Dubbing refers to the process of translating a video's speech and re-recording it. Lip Sync (Lip Synchronization) is the visual sub-process where mouth movements are adapted to the new audio to make it appear authentic.
Does AI Lip Sync work with multiple speakers?
Yes, advanced platforms like Dubly.AI feature Multi-Speaker Support. The AI automatically detects different voices in the video and applies Lip Sync and Voice Cloning individually to each speaker.
Is AI Lip Sync safe for corporate data?
That depends on the provider. Many tools use uploaded videos to train their AI models. Dubly.AI, however, is a German company and explicitly does not use client data for training public models.
Can I process long videos with AI Lip Sync?
Unlike many web apps that cut off after a few minutes, Dubly.AI is designed for enterprise requirements and processes even long keynotes, webinars, or e-learning courses exceeding 60 minutes in length.
Does AI Lip Sync alter the speaker's face?
With Visual Dubbing, only the mouth area (and parts of the jawline) is subtly adjusted to form the new sounds. The speaker's identity, facial expressions, and eye area remain completely preserved.
Does the Dubly.AI free trial include the Lipsync feature?
Yes. We believe you need to experience the full technology to understand its value. The free trial includes Generative Lipsync and Voice Cloning, not just simple audio translation.
Is there a difference between a standard "Video translater" and Dubly.AI?
Yes. A standard "Video translater" often only translates text or audio. Dubly.AI is a comprehensive AI solution that adapts the visuals (mouth movements) to the audio, creating a seamless experience.
Can I use Dubly.AI for long-form content?
Yes. While many free tools limit you to 60 seconds, Dubly’s engine is built for scale – from TikTok Shorts to hour-long corporate training modules.
Can I use translate video free tools to internationalize my content?
Yes, absolutely. Using free tools is a great starting point to test new markets without a budget. However, keep in mind that methods like subtitles or basic video translator apps usually only transfer information, not emotion. To truly internationalize your brand's personality and retain viewers, you will eventually need lipsync technology to ensure the audience feels connected to you, not just the text.
Does a free ai video translator work for all types of videos?
It works well for content where the speaker is not visible, such as screen recordings or faceless tutorials. However, for any video featuring a person speaking on camera, a standard tool often falls short. Because it lacks lipsync, the visual mismatch distracts the viewer. For content meant to build trust or emotion, you need a solution that adapts both the voice and the visuals.
Is there a free version of Dubly.AI?
You can translate your first video for free so you can validate the quality with your own files. We believe in letting you prove the value first.
Does this work for any language?
Our AI supports over 30 languages, covering the majority of global markets (English, Spanish, German, French, Japanese, Mandarin, etc.). The Lip Sync works universally across these languages.
How accurate is the translation?
AI translation is very good (95%+), but for critical content, context matters. That is why we offer Native Speaker Control (NSC) as an add-on, where humans review the AI's work. This combines the speed of software with the precision of a native speaker.
Can I automate this process?
Yes. For agencies, media houses, or companies with high volume, we offer an API. This allows you to integrate video translation directly into your content management workflow, removing manual upload steps entirely.
