In the CS6 workflow, you can import Adobe Story scripts directly into Adobe Premiere Pro. Unlike in CS5, you do not have to go through Adobe OnLocation to import scripts into Adobe Premiere Pro.
Adobe Premiere Pro automatically uses the imported Adobe Story script as a reference script. When Adobe Premiere Pro finds enough matches with the embedded script, it replaces the analyzed speech text with the embedded script text. Adobe Premiere Pro carries over the correct spelling, proper names, and punctuation from the reference script — benefits that standard speech analysis cannot provide.
A merged clip cannot be analyzed by attaching an Adobe Story script.
For more information, see Analyze speech for text XMP metadata in the Adobe Premiere Pro user guide.
