Say berry. Now say very. Watch your mouth in a mirror while you do it, and the two words should not look the same. For berry, your lips press flat together and pop apart. For very, your top teeth come down onto your bottom lip while the air keeps slipping through and buzzing. Two different parts of your mouth, two different jobs. If both words started with your lips mashing together, lips for berry and lips again for very, you just folded /b/ and /v/ into one sound. Most people who share your first language do the same.
This particular merger sorts speakers by where they come from. Spanish is the headline case: the letters b and v spell a single sound, so votar (to vote) and botar (to throw out) come out identical and very arrives as berry, vote as boat. Japanese, Korean, and Filipino speakers, whose languages have no native /v/, mostly reach for the nearest sound they own and land on /b/ too, so video comes out as bideo, and in Filipino, TV turns into tibi. However the merger happens, it costs English a contrast the language depends on constantly.
The letters b and v stand for two completely unrelated sounds. /b/ is a stop: your two lips seal together, block the air, and pop open, so the sound is a single burst you cannot hold. /v/ is a fricative: your top teeth rest on your bottom lip, leaving a narrow gap, and voiced air buzzes through it for as long as your breath lasts. Both are voiced, so you cannot sort them by listening for which is softer. The whole contrast is the contact. Does your bottom lip meet your other lip, or meet your teeth? Most learners already own the /b/; the job is to build a clean /v/ and keep it from spilling back over.
Two different sounds
English gives each of these one small upright letter, b and v, sitting near each other in the alphabet, and in plenty of languages they are two spellings for a single sound. In English they are not. They are made in different places and in different ways, and they hold dozens of words apart.
The B sound is a stop. Your two lips press flat together, seal the air off completely, let a little pressure build, and then release all at once. The sound is the burst at the moment they pop open, with a short voiced hum behind the lips while they are still shut. Because the air is blocked and then let go, a /b/ is over almost as soon as it begins; you cannot stretch it into a steady tone the way you can a /v/. (At the very end of a word like cab or web, Americans often skip the pop altogether: the lips seal, the voice trails off, and no little vowel leaks out after it.)
The V sound is a fricative. Your bottom lip rises to the edge of your top teeth, but instead of sealing it leaves a narrow gap, and you push voiced air through that gap until it buzzes. Nothing ever closes all the way, so the air keeps moving and the sound keeps going. Take a breath and buzz vvvvv until you run out, and it stays steady the whole time, the way fff or zzz can. That is the first tell. A /b/ is a single tap of pressure; a /v/ is a stream you can hold.
Here is the part that trips people. Both sounds are voiced: your vocal cords run for each of them, so they share the same low buzz, and you cannot tell them apart by listening for which one is harder or softer. What separates them is the contact, not the voice. For /b/, your bottom lip meets your top lip and the air stops. For /v/, your bottom lip meets your top teeth and the air leaks through. The same lower lip does the work both times; it just lands in a different place, and one place stops the air cold while the other lets it run.
That one switch, lip-to-lip or lip-to-teeth, runs through pair after pair in English: ban and van, best and vest, boat and vote, curb and curve.
| /b/ — lips meet | /v/ — teeth on lip |
|---|---|
| berry | very |
| ban | van |
| best | vest |
| boat | vote |
| base | vase |
| bet | vet |
| bat | vat |
| bent | vent |
| marble | marvel |
| curb | curve |
Read down both columns. If the two sides come out of your mouth as the same word, that is the merger this article takes apart, and the repair is mechanical, because you can both see it and feel it.
Why “the same sound” is the wrong frame
If your first language runs b and v together, the two feel like one sound you happen to spell two ways, which, in writing, they often are. So learners reach for “a little more buzz” or “a softer b,” as if the target sat somewhere on a dial between them. There is no dial. A sealed-lip burst and a teeth-on-lip buzz are not two settings of one sound, and the gap between them is easy to see.
The difference is not how soft or how hard you say it. It is whether your bottom lip meets your other lip, or meets your teeth. Lips, or teeth.
Watch yourself in a mirror, or in a phone camera. Say boat. Your lips come together and you see no teeth at all. Now say vote. Your top teeth drop onto your bottom lip and stay visible while the sound buzzes. That is the whole contrast, sitting right there on your face. Unlike a lot of pronunciation work, you do not have to feel for something hidden at the back of your mouth. You can simply look. If your lips press together on a word that is spelled with a v, the mirror shows you the exact moment it goes wrong.
It helps to see where this sits in a bigger picture. Three English sounds crowd the lips and trade places depending on the speaker: /b/, /v/, and /w/. Spanish, Japanese, Korean, and Filipino speakers tend to merge /b/ and /v/, the pair this article is about. German, Hindi, and Russian speakers tend to merge /v/ and /w/ instead, which is the subject of the companion piece. The /v/ sits in the middle of both collapses. That is why it is the single sound most worth building: a clean, teeth-on-lip /v/ pulls you clear of whichever merger your language leans toward.
How to make each sound
For almost everyone reading this, the /b/ is already yours, solid and automatic. The job has two halves: build a /v/ that stays separate from it, and then keep the new sound from spilling back over onto your bs.
Start from /f/ if you have it. The /f/ in fan is made in exactly the place you want: top teeth on bottom lip, air hissing through the gap. A /v/ is that same mouth with your voice switched on. Say a long fff, and then, without moving your lip or your teeth, turn on the buzz in your throat so fff becomes vvv. You should feel the vibration in your lip and your throat at the same moment. That is your target.
If your /f/ is shaky too (some first languages lack it), build the /v/ straight from the position. Rest the edge of your top front teeth lightly on your bottom lip, not biting, just touching. Push air out so it scrapes through the gap, and add voice. Keep the lip from climbing the rest of the way up to seal against your other lip, because the instant it seals you are back on a /b/.
The most common slip is the lip taking the short route home. If vote keeps landing as boat, your bottom lip is reaching for your top lip out of habit. Send it to your teeth instead and let the air keep moving. The hardest place to hold the new sound is in the middle of a word, in every or over, where the teeth have to drop in and lift back out between two vowels with no time to plan it.
Then watch for the rebound. Once the /v/ finally clicks, it is tempting to use it everywhere, and learners who have just won the teeth-on-lip buzz sometimes start sliding it onto sounds that were always /b/. Now boat tips into vote, the same pair running the other way, and a big problem drifts toward a vig problem. The cure is the same mirror in reverse: a /b/ should show your lips pressed flat with no teeth in sight. The point is one switch you throw on purpose, teeth for v and lips for b, rather than a buzz added to every word.
Which spelling is which
For this pair, English spelling is honest, which is not something you can say about most of the language. The letter v says /v/ almost without exception: very, even, love, give, travel, vote. English words rarely end in a bare v, which is why have, give, and live tack on a silent e, but the sound underneath is a clean /v/ every time. The letter b says /b/ just as reliably: big, table, robe, about.
The trap is not in the spelling. It is in the habit your first language built. In Spanish, b and v are two letters for one sound, so the page tells you nothing about which lips-or-teeth to use. English keeps the promise Spanish breaks: if the word is written with a v, it is the teeth sound, every time, and if it is written with a b, it is the lips. The instruction is short. Trust the letter on the page.
A small set of words hides a silent b, each one sitting next to an m or a t, where the b simply is not pronounced: climb, comb, thumb, lamb, debt, doubt, subtle. None of these is a /v/ in disguise; the b is just gone. And one tiny, very frequent word runs the other way. The word of is spelled with an f but, in careful speech, pronounced uhv, with a real /v/ at the end. (In fast speech that /v/ often softens away to a plain uh.) The point is just that the f there is hiding a /v/, not an /f/.
Train the ear before the mouth
You cannot reliably make a contrast you cannot hear. Plenty of learners can place a clean /b/ and a clean /v/ when they are thinking hard about each one, then lose the difference the instant a real sentence goes by, because the ear never learned to flag which one just happened. Perception comes first, and for this pair it comes quickly, because the two sounds carry a clear audible signature: a /v/ is a buzz that keeps going, while a /b/ is a quick burst that is gone the instant it starts.
The drill is minimal pairs fed to you out of order. Have a partner, or a text-to-speech voice, say one word from a pair at random: ban or van, boat or vote. You only sort, no speaking yet, naming which one you heard. When you can label fifteen in a row without stalling, your ear has built the category and your mouth has a target to aim at. A quieter version needs no partner. Take a minute of American speech with a transcript, an interview or a clip from a show, and mark every word that has a b or a v in it. Replay each one and answer one question only: did you just hear a /b/ or a /v/? You are teaching your ear to stop filing the two sounds under a single label, which is the step that makes the mouth-work hold.
Practice phrases
Read these out loud, twice each. Every line makes your mouth switch between /b/ and /v/, which is harder, and more useful, than drilling either sound alone. Slow down until each word lands on the contact you meant, lips or teeth, then bring the pace back up.

If a line trips you up at speed, that is the point of stacking both sounds into one breath. The lip has to seal and then drop to the teeth several times a sentence, and getting that timing automatic is what you are really drilling. The word obvious packs a /b/ and a /v/ right against each other; in natural speech the lips barely leave the /b/ before sliding onto the teeth for the /v/, so keep the /b/ light rather than popping it hard.
How different first languages handle this
Where you start depends on what your first language handed you. For this pair, most readers already own the /b/ and are building the /v/ from scratch. None of this is a deficiency. It is just the shape of the gap you are closing.
| Your L1 | Default slip | What to focus on |
|---|---|---|
| Spanish | very → berry (b and v are one sound) | Build the /v/: top teeth on the bottom lip, voiced air through the gap. Your soft Spanish b between vowels is still made with two lips, so bring the teeth in. |
| Catalan, Galician | v and b merge to one sound | Same as Spanish. The /b/ is fine; add a true teeth-on-lip /v/ and trust the spelling. |
| Japanese | video → bideo (no native /v/) | Your native fu is bilabial, so build the /v/ from the position (teeth on lip), keeping it firmly separate from your /b/. |
| Korean | very → berry (no /v/ or /f/) | Build straight from the position, not from /f/: teeth on lip, push air, add voice. |
| Filipino (Tagalog) | vote → boat; TV → tibi | Build the /v/ and hold it even mid-word, where the lip wants to seal back up. |
FAQ
Almost always because your first language uses a single sound where English uses two. Spanish spells one sound with both b and v, so the contrast was never there to hear; Japanese, Korean, and Filipino have no native /v/, so the nearest sound, /b/, stands in for both. The fix is the same in every case: build a real /v/ by resting your top teeth on your bottom lip and buzzing voiced air through the gap, then learn to keep it separate from the lip-sealing /b/ you already have.
/b/ is a stop: your two lips press together, block the air, and pop open, so the sound is a single burst you cannot hold. /v/ is a fricative: your top teeth rest on your bottom lip, leaving a gap, and voiced air buzzes through for as long as your breath lasts. Both are voiced, so the difference is not how soft or hard the sound is. It is the contact: lips meeting lips and stopping the air for /b/, lip meeting teeth and letting the air leak for /v/.
Your bottom lip is sealing against your top lip when it should be meeting your top teeth. Set up the /v/ on purpose: rest the edge of your top front teeth on your bottom lip, push voiced air through the narrow gap so it buzzes, and do not let the lip climb up to seal. A mirror helps, because the error is visible: on a clean v you can see your teeth on your lip, and on the mistaken berry your lips simply mash together with no teeth showing.
In Spanish, the letters b and v spell one and the same sound, so votar and botar are pronounced identically and the contrast English depends on does not exist in the first language. That sound is a firm lip-stop at the start of a word, the b a Spanish speaker reaches for in very, and it softens to a light, barely-closed version between vowels; either way the lips do the work, never the teeth. So an English /v/ feels foreign twice over. The repair is to bring the top teeth onto the bottom lip, which Spanish never asks of that letter, and trust that a written v always means the teeth sound.
That is overcorrection, and it is a normal stage. Once you can finally make a /v/, it is tempting to use the new sound everywhere, so words that were always /b/ start drifting toward /v/ and boat tips into vote. The cure is the same cue running the other way: a /b/ should show your lips pressed flat together with no teeth in sight. Switch the buzz on deliberately, and only for words spelled with v.
Context often rescues you, but not always, and the pairs that collapse are common: berry and very, ban and van, boat and vote, curb and curve. Even when listeners work out your meaning, a steady b/v swap is one of the more noticeable accent markers in English, because native speakers hear the two as completely separate sounds rather than near-misses. It is also one of the quicker markers to clear, since the whole difference is one visible move of the lip, which makes it worth a few days of focused practice.
The b/v merger is one of the more audible accent markers in English and one of the quickest to clear, because the whole difference is a single moving part you can watch in a mirror: lips together, or teeth on lip. Spend a few days only hearing the contrast, then a week running your mouth between the two through the lines above. Your lip only has to learn it has two places to land, the teeth and the other lip, instead of one.
