I just upgraded to the cloud version of Adobe Captivate, and I installed the Neo voices with it and tried them out with slide notes. I was disappointed to find that the voices mispronounced the word "reading" as "redding." I don't anticipate that we'll use this soon, but I'm wondering if there is any way to correct mispronunciations?
Here is a link to the video I posted before and the VTML user guide that you can download. Neospeech is no longer a company. They were absorbed by ReadSpeaker so the documentation that I've posted on my website is no longer easily available elsewhere. Hope this helps.
