Never use adjectives before said, but feel free to spice up your 'said's as with the mood.
yelled
barked
whimpered
gasped
roared
cried
giggled
laughed
whispered
shouted
All of each of these has their different emotions and reasons for using them. If a character is crying, you want to show that with using cried or whimpering before dialog. If they are angry, you can use roared or shouted. Each word is a different way of saying something. Never go out of your way to come up with crazy versions of said or foreign words that will distract the reader!
Said is best reserved for common dialog which no particular emotion is strongly affecting a character. Miffed or crest fallen, emotionless or tense, the best word for these inbetween emotions is 'said'.
