# 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.

- **240+** Languages  
- **90%** Faster time-to-market  
- **60%** Lower localization cost  
- **99.9%** Uptime SLA

### Media ingestion

Connect existing media repositories, DAMs, or upload directly. Supports all major video formats (MP4, MOV, MKV, ProRes) and audio formats (MP3, WAV, AAC). Batch-process hundreds of files simultaneously without manual handling or format conversion overhead.

## 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.
