Since many statistics say people are less likely to read text only, I have relied heavily on the text-to-speech option for all my courses but I agree with Don. The feedback I get from my courses are the voices sound robotic and the my users will immediately reject the course because of the voice of the text-to-speech person. I would like to have other options of more normal English speaking voices. I currently use Joanna but the users of my courses don't like any of the other voices. The management team has even considered recording all of our content in a recording studio and then adding it to the course but as we all know, that takes considerable time, resources, money, retakes, and prolongs the scope of the project. I look forward to some other voices options in Storyline 360 if available in the near future.
