Hi Julie,
You don't need to export anything. You can just save the voice script to your custom library and then load it onto any character you wish.
To save the voice script select the Animation tab in Content Manager and then select Custom > Voice Script. Now click the "+" Add/Save button at the bottom of Content Manager. This will save the voice script to your library where you can apply it to any head you like.
