Language learning FAQ
Clear answers about what UVE can and cannot do.
Can I slow videos below normal speed?
Yes. UVE supports playback from 0.1x, which helps with listening practice, pronunciation, and dense dialogue.
How do captions work?
On YouTube, Free can work with available captions. Pro adds OpenSubtitles search and the ability to load local .vtt or .srt files for compatible video.
Can I combine slow speed with louder audio?
Yes. Pair a slower rate with volume boost when dialogue is quiet, increasing boost gradually to avoid distortion.
Does UVE invent dual subtitles or auto-translate words?
No. UVE helps you use available caption tracks and local subtitle files. It does not generate dual subtitles or instant word translation.
