How to produce /v/, common errors, and practice activities
Sound Symbol
/v/
Typical Development
3-5 years
Expected Mastery
4-5 years
The V sound is the voiced partner of F—same position, but V adds vocal cord vibration. V typically develops slightly after F, between ages 3-5. Children may substitute B for V (using lips instead of teeth-lip contact) or produce a voiceless V that sounds like F. V appears in many common words including 'very,' 'love,' and 'have.'
Tongue rests neutrally and doesn't play an active role, same as for F.
Upper teeth gently touch the lower lip. Same position as F.
Upper front teeth make light contact with the lower lip, same as F.
Air flows continuously with friction, just like F. The difference: V is VOICED (vocal cords vibrate).
The most common V error. Lips close completely (like B) instead of teeth-lip contact. Very common in young children.
The position is correct but vocal cords don't vibrate. V sounds like F.
Lips round (like W) instead of teeth touching lip. Voice is present but position is wrong.
Tongue comes between teeth instead of teeth touching lip. Sometimes seen with frontal lisp.

Try these activities at home to help your child practice the V Sound.
Practice 'vvvvv' while feeling throat vibration. V should buzz! Compare to F which doesn't buzz.
Start humming 'mmmm,' then transition to 'vvvv' with teeth on lip. The humming activates voicing.
Practice pairs like 'ban/van.' For B, lips close. For V, teeth touch lip. Use a mirror to see the difference.
Touch throat while saying V. Feel the buzz. Compare to F (no buzz). This teaches the voice difference.
Consider a speech-language evaluation if:
Most children master the V sound by age 4-5, typically a bit after F (since adding voice is an extra step). If your child still consistently says B for V past age 5, consider a speech evaluation.
If position is correct but voice is missing, try: humming into V ('mmm-vvv'), feeling throat buzz, and comparing V words to F words. An SLP can use techniques like tactile cues and auditory discrimination to help add voicing.
B for V is common in young children and often resolves by age 4-5. However, if it persists, it can affect intelligibility since V appears in many common words. The substitution is usually easy to fix once children understand the teeth-lip position.
Often, yes. F and V use the same position—if a child can't produce F, they usually can't produce V either. However, sometimes children master F but struggle to add voice for V. Working on the pair together is often most efficient.
