As a DJ, you are judged by what you say as well as how you say it.
The first thing you need to work on is your voice. This is not to say that
you have to create a fake voice to use on the air that sounds like some
used-car ad on late-night TV; it simply means that you need to analyze how
you speak and make adjustments that will make listening to you more
pleasurable to your audience.
NASAL VOWELS: We in the Midwest pride ourselves on not having any
accent at all compared to people in the South or the East. Sorry to
destroy your illusions, but if you were born and raised in Illinois, you
DO have an accent, the most pronounced feature of which is the tendency to
drive your vowels right through your nose. This gives your voice a
brittle, harsh tone that will be accentuated when it’s broadcast and
sent through cheap car speakers. You don’t need to go through major
voice alterations; just watch your short A and long I sounds:
Practice saying, "I like lightning and limes, but Andy and Ann have
allergies to apples and hats." Okay, you can make up your own
sentences to practice.
VOCALIZED PAUSES: This is a biggie for a radio broadcaster. Sounds
technical, but all vocalized pauses refers to is the tendency for people
to insert needless words or sounds in the middle of their sentences
instead of pausing in silence. You still might not know what they are, but
have you ever listened to someone who couldn’t speak more than four
words without sticking in "you know," "like," or
"uh"? Isn’t it annoying? Figure out what words or sounds you
use for vocalized pauses, and work to limit and eliminate them from your
speech patterns. This will do you good as a speaker in all aspects of your
life, so this practice will benefit you in much more than just radio
broadcasting.
PACE: Too fast is much worse than too slow, but we will work to
find the happy medium.
PITCH: CHANGE IT! No one wants to listen to someone speaking in a
monotone unless he wants to fall asleep. The good DJ’s sound like
they’re having a conversation with their listeners—clear, informal,
friendly, with the normal ups and downs in pitch that we all speak with.
VOLUME: You’ll need to practice with the equipment to figure out
just how loudly or softly to speak. Some of you will have to tone it down
while others will need to turn it up. Your distance from the microphone
will also have a great impact on this, so work to maintain a consistent
distance so your volume also remains consistent.
That’s pretty much it—it’s not much more complicated than
that when it comes to your voice. Speak clearly, without nasal vowels or
vocalized pauses, at a pace comfortable for your audience with variation
in your pitch and a good volume and you’ll be all set.
