How to make the “f” sound:

• Softly lower your upper-front teeth to your bottom lip
• Turn off  your voice ( voice is the rumbling in your vocal folds.  Have your child/client place their hand on their/your neck during the production of “f” and “v”, and have them feel the difference between the two.  In the production of “f”, there should be no rumble or voicing.  While in the production of “v”, there should be a rumbling or voicing.)
• While keeping your upper teeth on your lower lip, have the child blow out a stream of air. 

Tricks and Tips for producing the “f” sound:

• A fun way to practice is to take turns and  see who can make the best angry cat noises using the /f/ sound!
• To visually show the child how air is released to produce the /f/ sound, hold a piece of string in front of their mouths, and have them try to move the string with the release of air. 
• If you have a board game that uses a spinner, have the child see if they can move the spinner using airflow from the /f/ sound.
• Rip a stick of gum in half, and place half a stick on the child’s bottom lip.  Tell the child that they should lower their top teeth just enough to create indents on the gum without biting down thru the whole piece.  Repeat with the other half and continue until have enough gum to blow giant bubbles!
