AI Dubbing

Any voice. Any language. Video or audio.

Any team with content to localize can use Ollang. Whether you run a global marketing function, manage a learning library, distribute a podcast, or ship a product with an international audience, Ollang handles the dubbing so you can focus on the work.

Upload a film, episode, podcast, training recording, or raw audio file and choose exactly how your dubbed content sounds: use a pre-trained library voice, clone the original speaker's voice to preserve their identity across languages, or create a completely new voice using Ollang's patented Unique Voice Creation technology. Then go further — use natural-language prompts to direct the AI's delivery: add warmth, urgency, or emphasis, just like directing a voice actor in the booth.

Key differentiator

Ollang is a multimodal multi-agent platform. For dubbing, that means every stage of the pipeline runs as a coordinated set of AI agents: transcription, translation, voice synthesis, lip sync, and quality review all operate together inside a single project, for both video and audio formats. The result is dubbed content that sounds intentional, not automated.

Key features

Seven capabilities. One unified pipeline.

Every feature works together inside a single project. No stitching tools, no handoffs.

  1. Video and audio file support: Dub MP4, MOV, MKV, MP3, WAV, AAC, and more. Ideal for films, series, podcasts, audiobooks, e-learning narration, and corporate training, whether or not a video track exists.
  2. Pre-trained, cloned and unique voices: Choose a library voice, clone the original speaker to carry their identity into every language, or build a brand-new proprietary voice using Ollang's patented Unique Voice Creation.
  3. Multi-provider AI engine selection: Select the AI voice engine that best fits your content, or let Ollang recommend the optimal engine per language and content type automatically.

  4. Emotion and delivery prompting: Write a plain-language prompt to shape the voice's performance: "deliver the opening with calm authority" or "add tension in the final act." The AI adjusts without re-recording.
  5. Frame-accurate lip sync: Mouth movements are synchronized at the frame level in every language, so dubbed video looks natively produced, not adapted.
  6. Speaker diarization and glossary: Automatically separates multiple speakers and assigns each a consistent voice. Brand names, technical terms, and proper nouns are preserved via custom glossary.
  7. Multi-agent QA and optional HITL: Multiple AI agents cross-check translation accuracy, timing, and audio quality before delivery. Add a human reviewer for broadcast-grade sign-off.
