Flair Phenomenon
a part that I mentioned my love of basketball I can insert a few seconds of audio recorded at a basketball court, i.e. the sneakers squeaking on the hard wood floor the ball bouncing as players talk to one another and the swish of the net as I score a basket. Then fade back into my narration. You can also use a music bed as a low level background to keep the listener engaged.
The most important thing to consider when using audio alone as a form of flair is your VOICE FLUCTUATION. Speak like you are talking to a friend not like you are reading a book. In general everyday conversation we accentuate certain words, we stress certain points by controlling the pitch of our voices and we even create emotion by bringing down the level to a near whisper then raising it again. Always remember to smile! Yes SMILE. Even if you are not on camera a smile can show through a microphone
