This was fun :-)
For this test project you type in whatever sentence text you want up to ten words.
Then tap the 'Say it' button.
The words will be inserted in each label left to right.
if there are less than ten words, the remaining labels will be set to empty text.
Each time a word is spoken, the background color of the label is set to a light green. (you can change that to setting text color if you prefer)
Try it out and make any changes needed and let us know if you have any further questions.
