This type of effect is called a multi-highlight.
You can find different threads here on the forum concerning this topic.
A recent one is this one: viewtopic.php?f=13&t=85247
Basically you need to time each repeat and replace the actual word with a #. Then in your effect script you add a multi in your effect column.
so for example:
Effect column: template syl noblank multi
This effect only works for the last syllable before the first #. You can't do multiple timings fore the first one. If you want to do that, use the method described in the thread above.
Hope that helps.
