F vs V Minimal Pairs
13 free F–V minimal pairs, sorted by position and ready to practice — the word list for voicing, when fan comes out as van.
What are F vs V minimal pairs?
The /f/ and /v/ sounds share one placement: the top teeth rest gently on the lower lip while air streams through. The only difference is the voice — /f/ is quiet air, /v/ adds a buzz from the vocal cords. A minimal pair puts that single switch side by side: fan and van, face and vase, leaf and leave.
This list targets voicing errors on the lip-teeth sounds — most often a /v/ that loses its buzz and comes out as /f/, so van becomes fan and leave becomes leaf. The two sounds also develop apart: most children have /f/ by around age 4, while /v/ typically arrives closer to age 5 — so a quiet stretch where /v/ defaults to /f/ is common before then. Contrasting them head to head gives the child a concrete reason to switch the buzz on, because fan and van are not the same word.
Voicing is one of the phonological processes covered in our guide to phonological processes.

Why minimal pairs work
Minimal pairs work because they make a sound matter. When the only thing separating two words is a single sound, saying that sound the wrong way changes what the child actually said — key becomes tea, cap becomes tap. That built-in feedback turns an abstract “say it this way” into a concrete mix-up the child can hear and fix.
This is the heart of the phonological (contrast) approach: instead of drilling a sound in isolation, you give the child a reason to keep the two sounds apart. Many children start to self-correct once they notice the listener heard the wrong word — the meaning contrast does the teaching. It is an evidence-informed technique widely used by speech-language pathologists, and it works just as well at the kitchen table as in the therapy room.
How to use F/V minimal pairs in therapy
A simple progression for SLPs and parents. If your child is in therapy, always follow your SLP's plan first.
- 1 Listen first. Read a batch of the pairs aloud so the child hears the F–V contrast many times, with no pressure to say anything back yet. This "auditory bombardment" tunes the ear before the mouth.
- 2 Point to the right one. Lay out a few picture pairs, say one word, and have the child point to the matching picture. This checks that they can hear the difference before they have to produce it.
- 3 Copy you. Have the child repeat each word after you, starting with the picture pairs. Model slowly and let them watch your mouth.
- 4 Say it on their own. Have the child name the picture without a model. If both words come out the same, that mix-up is the teaching moment — show how the sound changes which word they said.
- 5 Carry it over. Move from single words into short phrases and everyday talk, and send a few pairs home so practice keeps going between sessions.

F vs V minimal pairs — frequently asked questions
What are F vs V minimal pairs? +
F vs V minimal pairs are words that differ by only one sound — an /f/ in one and a /v/ in the other — such as fan/van, face/vase, and leaf/leave. Both sounds are made with the top teeth on the lower lip; the only difference is whether the voice buzzes, which is exactly what the child practices.
What phonological process do F/V minimal pairs target? +
They target voicing errors — most commonly devoicing, where the voiced /v/ is produced as a voiceless /f/ ("van" becomes "fan," "leave" becomes "leaf"). Pairing the two directly shows the child that the buzz of the voice is what separates the two words.
How do you use F and V minimal pairs in speech therapy? +
Read the pairs aloud so the child hears the contrast, have them point to the word you say, then repeat each word, name the pictures on their own, and finally use the words in phrases and everyday talk. A hand on the throat makes the difference concrete — /v/ buzzes and /f/ does not — and a mirror helps confirm the teeth-on-lip placement is the same for both.
When do the F and V sounds develop? +
They arrive about a year apart: /f/ reaches 90% mastery by around age 4, while /v/ reaches it by around age 5 (McLeod & Crowe, 2018; Crowe & McLeod, 2020) — so some /f/-for-/v/ substitution in between is developmentally common. If a child is past age 5 and still devoicing /v/, or is hard to understand, it is a good time to check in with a speech-language pathologist. This page is informational and is not a diagnosis.
