Re: Storyline's Text-To-Speech v3 and v2

My organization uses other text-to-speech tools such as WellSaid but I decided recently to dabble in Storyline's text-to-speech as well. I like the quality of a lot of the voices, but I am having a little bit of trouble with the v3 Beta. For example, I am using the voice Bill for a reporter/broadcaster role and I like how the v3 allows me to put in things like [laughing] or [emphasis] but he is talking a little too slowly for me as well. 

For that reason, I'm trying to make these broadcaster lines with v2 because I can adjust the speed he talks with, but I need certain parts to have him laugh or chuckle, so I use v3 for those lines. However, the difference in his tone is between v2 and v3 seems stark enough that it is somewhat distracting to me, and I assume would be for the learners. Does anyone have any input on how I might be able to get v2 and v3 of Bill's voice to sound a little bit more the same?
