What to listen for
B and F are the usual substitutions. If the mouth position looks right but the sound is wrong, it is almost always voicing: have the child feel their throat and notice the buzz that V has and F does not.
Common V errors
- Substituting /B/ for /V/ (e.g., "ban" for "van")
- Substituting /F/ for /V/ — devoicing (e.g., "fan" for "van")
- Not maintaining voicing throughout the sound
- Using both lips instead of teeth on lip
- Producing the sound too weakly
How to run V practice
Short and frequent beats long and occasional. Five to ten minutes on most days produces more correct V productions over a fortnight than one long weekend session, and it is far easier to sustain.
Work in one position at a time. Get V reliable at the beginning of words before moving to the middle and at the end — mixing all three from the start usually slows everything down.
Keep correction light. Model the word correctly and move on rather than asking for a repeat every time; a child who feels tested talks less, and less talking is the opposite of what V practice needs.
Tips for the V sound
- Since /V/ uses the same mouth position as /F/, start by making sure your child can say /F/ well. Then add the voice.
- Have your child place a hand on their throat while saying /V/ to feel the vibration. Compare to /F/ (no vibration).
- Use the "buzzing" cue: tell your child /V/ is the "buzzy" version of /F/, like a vacuum cleaner ("vvvvv").
- Practice contrasting /F/ and /V/ pairs: fan/van, fast/vast, fine/vine, feel/veal.
- The "vacuum cleaner" game: have your child pretend to vacuum while making the /V/ sound continuously.
- Start with /V/ in the initial position (van, vet, vine) as it is often easiest there.
- Use mirror practice so your child can confirm the teeth-on-lip position while feeling the throat vibration.
