DupDub Core Functionality
DupDub structures workflows into discrete modules that accept text, audio, or image inputs and output voiceovers, dubbed videos, or talking avatars. Text input routes to AI Writing or Text-to-Speech modules. Audio input routes to Voice Cloning and Voice Store modules to produce cloned voices or sound effects. Video input routes to Video Editing, Subtitle Alignment, and Video Translation modules for automated transcription, translation, and dubbing. The system exposes APIs for programmatic access to TTS, cloning, and downloader features. DupDub lists support for multi-voice mixing inside a single file and voice editing controls for pitch, speed, and emotion parameters. The architecture references GPT for AI writing and proprietary models for audio synthesis and avatar motion.
