Be careful about adding EQ and Compression, if you can hear it, you probably have added too much. Your ears will tell you when you have it right!

For the record:
Compression is used to balance the vocal dynamics, make the loud bits less loud and the soft bits louder. If you can hear every syllable, you probably don’t need it. It you get breathing and pumps you have whey too much. Compression is different to limiting which truncates a signal once it passes a certain point. A common mistake when first using compression is too slow an attack time (the time before the compression in applied one the signal passes a user defined threshold).

EQ can be used to add presence and get rid of rumble (from holding the mic) and proximity effect, even add brilliance to a voice. Careful you don’t boost too much as it can become obvious you are EQing the **** out of a vocal track. I normally try to keep the vocal sounding natural.
