Upload a video or audio file. Dubline transcribes it, translates the captions into the languages you need, and exports standard subtitle files. Voice cloning and AI dubbing are available as premium add-ons for a truly native-sounding multilingual voiceover.
Each step maps to a point in the processing timeline — pause, download, or continue at any stage.
Drop in a video or audio file. No transcoding needed on your end.
Speech is recognized and turned into time-coded captions automatically.
Generate multiple language versions at once, with timing kept in sync.
Export SRT/VTT, or upgrade to AI dubbing for a full voice track.
Click below to preview a sample result — the live version accepts real file uploads.

Automatic speech recognition from video or audio, with accurate, time-coded original-language captions.
Generate 30+ language versions in one pass, with timing kept in sync, and batch-export SRT/VTT.
Upload a short sample and generate a cloned voice for use in multilingual dubbing, keeping the original speaker's character.
Turn translated captions straight into a voice track, using a cloned or built-in voice, across multiple languages at once.
Process many files at once, or plug directly into your own content pipeline via API — built for teams and MCNs.
Export standard SRT / VTT files that drop straight into CapCut, Premiere, Final Cut and most editors.
Covers the languages that matter most for global content distribution, with more added over time.
Transcription and translation quotas reset daily. Voice cloning and AI dubbing are Pro features, billed by usage or subscription.
Accuracy depends on audio quality — clean, single-speaker audio performs best. Technical jargon or heavy cross-talk may need light manual review.
A cloned voice is only ever used for content you generate. It is never shared with other users. Make sure you have the rights to any voice you clone before uploading it.
Most common video and audio formats on upload; subtitles export as standard SRT / VTT, ready to drop into any editor.
Free quota resets daily. For higher volume, or for voice cloning and dubbing, upgrade to Pro and pay by usage.
