It’s only natural that I get a lot of inquiries about how to break into the Voice Acting world. Several years ago, after a seminar, a guy asked if I would listen to some of his work. He was a very good talent, but listening to his demo, I noticed something. I told him, “If I were playing the notes on a keyboard that you hit with your voice, you always seem to end sentences on the exact same note, and it almost always goes down in pitch.”
He was surprised by this, and said he had never noticed that before.
Going down in pitch repeatedly can make you sound predictable, or even bored. You should (of course) VARY your deliveries. And I also believe that thinking about it in a musical context can add a dimension.
Tip: I always picture the person – the ONE person – that I’m talking to. That seems to ‘shape’ the delivery, and helps avoid the “same note” thing.
It’s called Voice ACTING for a reason.
