LangSwap

LangSwap provides an AI dubbing workflow that takes a user’s talking-head video and produces a version in a different language while preserving the original speaker’s voice and tone. It targets creators who want to maintain a personal voice in multilingual videos, without using studio voice actors. The service emphasizes that the voice remains recognizably the same speaker after translation and keeps the original cadence and expression.

From upload to dubbed video, LangSwap explains a three-step process: upload your video, pick a language, then download your dub. The system is designed for single-speaker videos, and it includes subtitles in the final product. The hosted workflow aims to be automated and centralized, handling translation and voice cloning in one sequence.

LangSwap highlights that voice cloning carries your voice and tone into the new language, ensuring you stay recognizable as the speaker. It presents a choice of supported languages and notes that processing time depends on video length and queue.

LangSwap outlines plans and availability: first video is free, then a per-video price up to a 30-minute limit, with the code available under an open-source license. It emphasizes that the pipeline can run locally on users’ GPUs, avoiding cloud per-minute fees, and mentions the AGPL-3.0 license and self-hosting options. It also points to hosted dubbing as a separate path with pricing in place.
