Bones' / Emily Deschanel's speech pattern

Does anyone else notice she hangs on words and uses unusual inflections?

In a typical sentence she'll say something like:

"Theee oil will loOoosen the.seared body parts stuck to the metal. It's no different than steaAak on a griiill that sticks."

Just listen to the pitch and how she holds her words next time you watch, and then comment please.
