AI dubbing and localization editor that transcribes, translates, subtitles and dubs video/audio in 50+ languages with segment-level editing.

What it does

Speechlab is a localization platform for video and audio that combines transcription, translation, captioning, subtitling and AI dubbing in a single editor. Unlike black-box dubbing tools, it gives users a waveform-level editor to review and fix transcripts, translations and voice output before export, including re-dubbing individual segments.

How to use: Users upload an audio or video file to the SpeechLab platform. The service then generates an editable transcript, translation, and dub using AI. Users can download captions, subtitles, and dubbed audio/video with or without the original background audio.
