Is there a way to download a script once the video is completed for someone who may have hearing disabilities?

 Although this does not exactly fulfill your request:

I recommend writing the script first, then recording the voiceover, then making the videoscribe video. If you upload the video to youtube or a website, you can include a link to the script in your description.

Or you can use text elements to subtitle  your video.

Or you can use youtube's closed captioning feature to add captions.
