There are various ways, using mulptiple layers and playing with opacity, if I understand what you mean.

basically what i want to do is have the particle appear,move,disappear as the text does. in other word make it do whatever the text does without manually inserting keyframe etc.

I think I can figure what you are trying to achieve, but it's impossible. Particle systems are calculated dynamically and there is no way for them to guess anything. This means until the moment the particle is born it does not know anything about its environment and cannot react to it. Anyway, I figure what you want could be done in some way using expressions, but it would be major math because there is always a delay between the particles being emitted and the time when the particle system is fully formed. This run-up time would even vary for words with different lengths so it would be quite tricky. Keyframing seems far simpler and may not be that hard depending on the amount of text you intend to use.

Do you want something like that ?

You don't need keyframes in the particle system for something like that...

Here's the project with 2 missing files : the video and the font. It should still work.
I used a script I did in order to create the text animation.
