I thought your question was more about how to get words from the file.
In my example one word is shown at a time when Space key is pressed. You can change this to "Every X seconds" or some other event. Or you can display all words in a loop, here is an example with 0.5 delay between words:
Repeat tokencount(fileData, " ") times
Wait 0.5*loopindex
Text set text to trim(tokenat(fileData, currentWord, " "))
Add 1 to currentWord
