Why TranSpeaker

Well-timed cues

Captions are segmented by natural pauses and sentence ends — readable lines, never one giant block.

Translated subtitles

Generate subtitles in the original language and translate them into multiple languages in the same job.

Standard SRT & VTT

Export formats that work everywhere — YouTube, video editors, media players and the web.

Preview before you export

Once uploaded, check every cue on your actual video in the player before you export a single file.
