# Lip Synching

It can be a difficult task to shape a characters mouth so that it matches the sound at the right frame.

To solve this problem Toon Boom Studio provides you with the lip sync feature which analyses the contents of a sound element and generates a lip chart based on the eight animation phonemes (A, B, C, D, E, F, G, and X, which represents silence). You can refer to the lip chart positions as you draw the shape of you character’s mouth.

To generate a lip chart for a sound from the Exposure Sheet:

1. In the Exposure Sheet, [Control]-click the sound you want to affect and select Show Lip Sync from the pop-up menu. A checkmark appears next to the command to show that it is active.

Toon Boom Studio analyzes the selected sound clips and assigns a lip sync letter to each sound cell. All the cells that have a sound file in them display a cartoon face that mimic the sound at that specific frame.

2. To show/hide the lip sync images that represent the lip position at each frame, click the Contextual Menu button and select View > Thumbnails.

To generate a lip chart for a sound using the Sound Element Editor:

1. Select the Sound element and select Element > Edit Sound. The Sound Element Editor opens.

2. In Sound Element panel, select the waveform you want to generate the lip chart for.

3. Click Lip-sync. A progress bar appears as Toon Boom Studio analyzes the selected sound clips and assigns a lip sync letter to each sound cell.

Each lip chart image displays a letter which corresponds to the sound cell shown in the exposure sheet.
