Start here

V /v/ and F /f/ are made with exactly the same mouth shape. Your bottom lip lightly touches your top front teeth while air pushes through. The only thing separating them is voicing. For /v/, your vocal cords vibrate (you can feel a buzz in your throat). /f/ is a steady stream of air without the vocal buzz. German, Spanish, and Mandarin speakers all struggle with these sounds in different ways. At the ends of words, German and Russian speakers often let an unvoiced /f/ slip in for a /v/.

Why people mix them up

If your ear blurs them, here's why.

Many languages don't use the /v/ sound at all, or they treat it very differently than American English does. Mandarin Chinese doesn't have a /v/, so speakers often substitute an /f/ or a /w/, turning very into ferry or wery. Spanish speakers often merge /v/ with /b/, making van sound like ban. German and Russian speakers might pronounce /v/ perfectly at the start of a word, but automatically turn it into an /f/ at the end of a word due to a rule called final devoicing. This makes leave sound exactly like leaf. To fix it, you have to consciously keep your throat buzzing all the way through the end of the word when saying /v/. Spelling sets a trap, too: the word of is pronounced with a /v/ (uhv), while off is pronounced with an /f/ (ahf). Many learners read of and accidentally say off.

How to practice

Train the muscle, then the ear.

4 short drills. Do them out loud: feel the change inside your mouth before you try to hear it.

The throat-buzz check: place your fingertips on your throat and hold a long fffffff. You should feel nothing. Now switch to vvvvvvv. You should immediately feel a strong buzz. Practice toggling back and forth: fff-vvv-fff-vvv.

Mirror practice: look in a mirror and say van and fan. Your mouth shouldn't change shape at all between the two. Make sure you aren't pressing both lips together (which makes a /b/ or /p/).

Read minimal-pair sentences out loud: The fan is in the van, Prove the proof, A very fairy tale. Exaggerate the buzz on the /v/ words so your brain registers the contrast.

Stretch the ending: when practicing words that end in /v/ like leave or five, hold the final buzz for a full two seconds. This trains you to not let it fade into an /f/.

FAQ

Common questions about Van vs Fan.

Why do "leave" and "leaf" sound the same when I say them?
You're likely dropping the vocal cord vibration at the very end of the word. Many languages automatically turn voiced sounds like /v/ into voiceless sounds like /f/ at the end of a word. To an American ear, a devoiced leave is just leaf. You have to consciously keep your throat buzzing all the way through the final consonant. Try holding the /v/ for an extra second to build the habit.
Should my top lip do anything when saying V or F?
No, your top lip should stay completely relaxed and slightly lifted out of the way. Only the bottom lip moves. A common mistake is bringing both lips completely together (which turns /v/ into a /b/), or rounding your lips (which turns it into a /w/). Let your top teeth rest lightly on the soft, inside part of your bottom lip. If you look in a mirror, you should clearly see your top front teeth for both of these sounds.
How do vowels change before V and F?
Vowels are noticeably longer before a voiced consonant like /v/ than before a voiceless one like /f/. This is one of the rhythm patterns that shapes casual American speech. The vowel in leave is stretched out and held slightly longer than the same vowel in leaf. Even if your /v/ isn't incredibly buzzy, Americans will hear the longer vowel and correctly guess that you're saying leave instead of leaf.
