Could be interesting. I don't have a lot of programming experience. If I did, I would, but...

You could just use a PowerPoint presentation and time the slide show to show each line after a few seconds (or each word). This can do exactly what you want, you can animate the text to fade in so it's comfortable to read while trying to relax. It may be good enough, try it out.

Who knows if it's been done? It probably has, but we can do it too. Autohotkey might do what you want. It's a little bit scripty though.

Otherwise a python program could handle this pretty easily if you format your text file like an html doc. I see it as two step process:

1. Create a standard script format.
2. Use program to display words give script input and script speed.

Example file:

myscript.txt

//Randomized words
<deeper=falling,further down, more and more relaxed>
<submit=obey, agree, surrender, relinquish, succumb>
<masterbate=rub,stroke,performing hand to gland combat>
<orgasm=cum,explode,climax,peak,spasm>

//Begin script
<speed=5>
script...<deeper> script script...
<speed=3>
script...script <deeper> script <submit>...
<speed=2>
5 <submit>
4 <submit>
3 <submit>
2 <submit>
1 <submit>
0 <submit>
<speed=1>
script <submit>....script<masterbate>....script<submit> <masterbate> script....
script <orgasm> script...
<speed=3>

Wake up!
