Hi,
After creating captions, check out the Create Captions dialog box for options on how words are displayed.

You may be able to dial it down to one or two words per caption. Give that a play and share any settings with the community.
I just tried it and put all the sliders to the left, and it worked for word-by-word text delivery with only a few exceptions. Please try again with all the sliders to the left and report back with the results. I wish you luck!
Thanks,
Kevin
