The Problem
In a globalized world, video content is king—but language remains a major barrier.
- Most translation tools are either manual, time-consuming, or poorly synchronized.
- Voiceovers sound robotic or out of sync, failing to preserve original emotion or pacing.
- Companies and content creators waste hours syncing, trimming, and editing audio to match speakers.
The Solution:
AI Video Translator & Voiceover Engine
An end-to-end, automated platform that:
- Transcribes audio from any video (in English, Japanese, etc.)
- Translates it using advanced NLLB (No Language Left Behind) models
- Naturalizes the dialogue using a custom LLM rewrite pass
- Performs Speaker Diarization with gender detection (via Pyannote)
- Assigns Voices dynamically via TTS (Edge-TTS or Coqui) based on gender + language
- Mixes Voiceover with original background music using AI source separation (Demucs)
- Syncs Output perfectly with the video, preserving timing and pacing
