You can quickly search and shorten word gaps by selecting and choosing Shorten word gaps…; or, you can select and choose to search for word gaps. This will display a list of all the detected word gaps in the Properties Panel. You can then adjust the word gaps from the search panel at the top of the Script editor.
Set a word gap length and select Apply to all in the search panel. Or, you can preview each detected word gap section by selecting it in the Properties panel, set the new word gap length, and select Apply. After shortening the word gap, Descript will playback the audio section with the new word gap.
