Frequently asked questions
Can StreamVox subtitle untranslated Japanese anime?
Yes. StreamVox recognizes Japanese speech and translates it into your language in real time, so you can watch raw episodes without official subtitles.
Does it work over Netflix or YouTube?
Yes. The overlay floats on top of any player, so it adds live subtitles to Netflix, YouTube, Twitch, and local video files alike.
Will the subtitles cover the video?
You decide. The overlay is fully adjustable — move it, resize it, and set transparency so it never blocks the scene.
How many languages are supported?
StreamVox supports 49+ languages, including Japanese, Korean, and Chinese, with a film profile tuned for on-screen dialogue.
Does it save any of the video or audio?
No. Audio is processed live and never stored, so nothing you watch is recorded or uploaded.
