Here is something else to think about as you start exploring voiceover…
Part 3 – Articulation
OK, this should be obvious. You need to be able to enunciate! Mush mouths need not apply.
Sure, you can incorporate sloppy diction into a character, but for consistent paying voiceover work, you need to be able to articulate clearly.
Many people simply don’t open their mouths so that the sounds can get out. Is this you? Record yourself reading something and play it back. Analyze what you hear.
Again, as with an unusual voice quality, you can use sloppy articulation to create a distinct character, but you need to be able to drop that character when the next project comes along.
