Best way to trigger voice lines?

I have to say that I don’t fully follow you. This is what I am doing:

I have a parameter called “Speak” that is set to User:Labeled and then value 0=Stop, Value1=WordA, Value2=b etc.

I have placed the “Word A” (etc) transition at the end of each word.
The problem is that if I quickly skip the “Speak” value, faster than the words are being said/are finished, there will be underlying words that will not be played.

Thanks
