Some engineers hate it.
Learn to play with the words and the timings to complement background music or SFX - or to work against them. Elongating a certain syllable can sometimes make all the difference. But don't be afraid to ask to hear a snatch of the music so that you can get the right feel. If you are supposed to be shouting above the wind or a hubbub - ask the engineer to play the relevant sound effect down your cans during the recording. Lovingly caress syllables - sometimes.
