Sing along with the karaoke and lyrics to identify mistakes in the text.
Adjust the global timing of the lyrics so they appear a fraction of a second before the vocals.
For karaoke, the recommended value is 0.5 seconds.

If the lyrics were generated by AI, use the "Advanced Lyrics Editor" for precise timing adjustments:

Before preparing the video, listen to the song with the lyrics several times to ensure the timing and text are accurate and easy to follow.
Before preparing the video and after making text corrections, have someone else sing with the lyrics and see how they react to the singing.
This way, you will gain more accuracy in correcting the lyrics, the need for punctuation marks, and possibly reducing or splitting the text with adjacent blocks.
