AI Dubbing Studio

Beta commercial application for automated video and audio localization.

AI Dubbing Studio converts source media into a dubbed version in another language while preserving the original speaker identity and timing as closely as possible. The workflow covers transcription, translation, voice generation, and final media rendering in a single process.

Product overview

• Input: audio or video files
• Process: transcription, translation, voice synthesis, and media reassembly
• Output: dubbed audio, translated transcript, and final video when applicable
• Use case: localization for content teams, media publishers, and multilingual distribution

Technical stack

• WhisperX: transcription and alignment
• Groq: translation
• Zonos-2: voice cloning and speech generation
• FFmpeg: audio and video processing
• FastAPI: backend orchestration
• Cloud storage + worker pipeline: job handling and delivery

Commercial beta status

This project is a beta commercial application. It is intended for controlled production evaluation, deployment, and operational use, with outputs suitable for teams that require a practical dubbing workflow without a manual editing pipeline.

Delivered output

• Dubbed audio file
• Translated transcript
• Final dubbed video (when the source is video)
• Download links provided through the application workflow

Notes

This repository is structured for a managed product workflow rather than as a local-run developer guide. The platform is intended to support repeatable, production-oriented localization work in a controlled deployment environment.
