Decibella and Her 6-Inch Voice

Decibella is a loud talker. A really loud talker. She's so loud, she's hurting ears, startling wait staff, disrupting classmates, and annoying moviegoers. She doesn't realize different environments and situations sometimes demand a softer, quieter voice. That is until a caring teacher introduces her to the silly-sounding word "Slurpadoodle" and the five volumes of voice (Whisper, 6-inch, Table Talk, Strong Speaker, and Outside).
