Developer Builds Open-Source AI Pipeline to Dub Anime and Movies Using Python

A developer named Sumit884 has released dub_movie, an open-source Python project that automates video dubbing by combining speech recognition, translation, and text-to-speech generation. The pipeline uses tools including Faster-Whisper for speech detection, Edge TTS for voice synthesis, and FFmpeg for final video rendering. It is primarily designed for Japanese anime and movies with SRT subtitle files, translating dialogue into other languages such as Hindi while preserving character-specific pitch and tone. The system breaks dubbing into separate stages — including speaker identification, audio separation, and timeline synchronization — to ensure translated speech aligns with original dialogue timing. The project requires Python 3.10 or later and supports optional GPU acceleration for faster local translation and processing.
