ThioJoe/Auto-Synced-Translated-Dubs
Automatically translates the text of a video based on a subtitle file, and then uses AI voice services to create a new dubbed & translated audio track where the speech is synced using the subtitle's timings.
Supports multiple translation engines (Google Translate, DeepL) and TTS providers (Google Cloud, Azure, Eleven Labs) with configurable voice selection per language. Uses subtitle timings to calculate required speech duration, then either time-stretches synthesized audio or performs two-pass synthesis to match original pacing—Azure TTS can specify duration natively, eliminating stretching. Includes companion tools for batch YouTube operations: adding audio tracks to video files, translating titles/descriptions, and syncing auto-generated transcripts via the YouTube API.
