Type in a word and watch the girl mouth what you typed. For the "oo" sound, type "u". For the "eh" sound, type "i". To double the length of a sound, just type it twice. Sometimes it's best to skip letters entirely. Example: A yodel could be written as "yodlaaaieeeuuu" Click the Cloud for a delicious surprise.
Thanks to wgrscratch for the original graphic design and mouth animations. I changed the "F/V" image to be more toothy and added the Eh" sound
