# Recomputing the Lip Chart

When you generate the lip chart for a sound in a sound element, you can either accept the lip positions assigned by Toon Boom Studio or assign your own lip sync images.

However, if you change the sound’s start frame or reassign its lip position, you can reanalyze the sound and regenerate the lip chart for it. This erases any manual modifications you may have made to the lip assignments in the lip chart.

To recompute the lip chart for a selected sound from a Sound column:

1. In a Sound element, [Control]-click a cell that contains the sound file you want to recompute the lip sync on.

2. Select Recompute Lip-sync from the pop-up menu. The lip assignment for each frame is recomputed, erasing any modifications you may have made.

To recompute the lip chart for a selected sound from the Sound Element Editor:

1. Click the sound in the Sound element panel in the Sound Element Editor.

2. Click Lip-sync. The lip assignment for each frame is recomputed, erasing any modifications you may have made.

| Regenerating the lip chart erases any customized assignments you make.
