Different color from the subtitle

[paulo]

I have DVD Workshop 2
Hello everybody!
I got to put subtitle in my video.
Now I would like to put a color different from the subtitle, when the word was pronounced goes changing.
For exemple the subitile is:
"Good morning my dear teacher". (the sentence all is in green color)
When the word "Good" goes pronciada I would like that the color change for red.
That is possible?


Thanks

Paulo
