In their own words
DubDuck
DubDuck is a web service for translating and dubbing video dialogue. It transcribes and translates speech, clones speakers’ voices, and lip-syncs dubbed video into 40+ languages. Its editor provides dialogue and translation workspaces, speaker controls, a frame-accurate timeline, and segment-level re-dubbing. The documented workflow covers upload, source and target language selection, transcription and editing, calibration, dubbing, preview, and export. New accounts start with $10 in free credits, while videos dubbed before payment show a visible DubDuck.com watermark. Beta documentation limits uploads to 3.5 minutes and 50 MB, although the homepage describes uploads as any format and length. Dubbing costs $1.95 / min per minute of dubbed dialogue, billed by the second; only dialogue is charged, and calibration is billed the same way during the first dub. Top-ups cost $5.00 per once, $10.00 per once, or $25.00 per once. Credits do not expire while the account remains active. Voice characteristics are used for the project and discarded shortly after rendering.
pyVideoTrans
pyVideoTrans is free, open-source software for translating videos that contain clear human speech. It automates speech recognition, subtitle translation, AI dubbing, and video assembly to produce translated audio and subtitles. It also supports batch transcription into timed SRT files, subtitle dubbing, and batch SRT translation while preserving timestamps and formatting. The project offers a desktop GUI, WebUI, and command-line interface, with documentation for remote access, server deployment, and Docker use. It lists more than 30 channels, including Faster-Whisper, F5-TTS, Qwen3-ASR, and Edge-TTS, with local offline and online API options. Source deployment instructions cover macOS, Linux, and Windows, and a Windows 10/11 package is provided. The software is described as having no feature limits or login requirement under GPL-V3. Third-party API use may incur separate charges, and users provide their own accounts and keys.
