There is no such feature. What did you have in mind for the speech with your idea?
My ideal is to be able to read each page of text at my own pace, and press a key to go on to the next. That's all.
I don't like having to page back if I'm not fast enough to read a particular page for whatever reason, and I don't like paging ahead if I read faster than I'm "supposed" to, because I often hit the key just as the system also pages ahead, thus turning over two pages at once.
It's a minor complaint, but as a huge fan of the original game, I'm disappointed to see the interface take a step backwards in this cool new version. In the original, "minimum" text speed was infinite. You could go out to lunch, take a trip to Monte Carlo, get married and have a few kids, and come back to your keyboard to find that it was still on the same page of text until you told it to page forward. The new way gets on my nerves.
Thanks for asking; I appreciate it.
