Take a rubber band and hold it with your two thumbs.

Every time you want to stress a word by changing pitch, pull on the rubber band.
Stretch it out gently, don't jerk it sharply.
Make a looping ∞ figure with it and do the same with your voice.
Use the rubber band and stretch it out every time you change pitch.
