Answer
Not sure what you are looking for.  If the effects you are looking for are to be mixed to your source then google "sound effects free" and you will find a host of sound effects that will give you just about anything you can imagine.

If you are wanting to alter the sound of your recorded voice you need a stand alone box that can be placed in the line or when you do the mix.  If you go to:

There are a number of sound effects generators an eqs that can produce various kinds of sound effects during recording or mixing.

Hope this helps.  Good Luck.
