Why most karaoke lyrics are timed wrong (and what 'right' looks like)
Word-by-word bounce is not the goal. Here's the timing model singers actually need, and how to proof for it.

There's a specific kind of bad karaoke video: every word flashes exactly as it's sung, and somehow it's harder to follow. That's because you're not building a transcript. You're building a cue sheet for a human who needs to breathe.
The three timing mistakes
1. Cueing on the vowel
Automatic word timers fire when the vowel is detected. Singers need the cue on the consonant before it — and really, they need the whole line a beat early so they can read ahead.
2. Word-level everything
Highlighting each word is great for fast rap verses and pointless for a ballad where one word lasts two bars. Line-level with a smooth wipe is what people can actually track.
3. No lookahead
If the next line isn't visible, the singer is guessing. Every good karaoke display shows the active line and the next one, dimmed.
What 'right' looks like
- Line appears ~600 ms early, wipes across at the sung pace.
- Next line is visible underneath at ~45% brightness.
- Section breaks show a countdown or a bar of empty stage, not a wall of text.
- Long instrumental gaps show "♪" or a subtle progress bar so nobody thinks the video froze.
How D107 handles it
The Builder places lines on the waveform with lookahead baked in. You proof by ear: play, nudge, done. Because timing is line-based, a single nudge fixes the whole tail of the song rather than forcing you to re-tap 300 words.
Proofing checklist
- First line of each verse lands early, not late.
- Chorus lines wipe evenly, not in a burst.
- Outro has a hard stop.
- Watch it once on a phone with the sound off. If you can follow it, singers can.
FAQ
Does D107 do word-level highlighting? Line-level wipe by default, which is what most singers need. Fast sections can be split into shorter lines for the same effect.
Can I import an existing LRC file? Bring the plain lyric sheet; the Builder will re-sync against your actual audio, which is usually more accurate than a downloaded LRC anyway.
What about duets? Use singer lanes — each singer gets a color, and shared lines show both.
