Live captions in three steps
Launch your game
Start any game or party chat. StreamVox listens to the audio your computer plays — no mods or game files touched.
Turn on Borderless mode
Use Borderless (windowed-fullscreen) so the StreamVox overlay can stay on top of the game while you play.
Read as you play
Dialogue, cutscenes, and teammates are translated live and shown in an overlay you position out of the action.
Why StreamVox for gaming
Play untranslated titles
Enjoy Japanese and other region-locked games before any localization — StreamVox subtitles the dialogue in real time.
Follow voice chat
Understand teammates and opponents in multiplayer — even when the lobby isn't speaking your language.
Overlay that stays out of the way
Move, resize, and fade the overlay so subtitles never block the action on screen.
