I've not seen my current yorkie girl do anything yet, but our younger/smaller jack russell has barked and even one time howled in her sleep. the one time she howled, woke everyone in the house up to see what was wrong lol ^^; Our past yorkies occasionally did little weird barks but our male did this sort of soft "oink" snore when he slept.
