The setting must be on, the plan cannot be Free, and the lyric source must include word-level timing.
Frequently asked questions
Why is Karaoke off on Free?
The Overlay tier disables it. Trial and Pro can use it when timing exists.
Karaoke
Karaoke is not a separate overlay product. It is a word-level fill on the current line. StreamLyric never invents that fill from plain text.
