Spanish b vs v: they are the same sound
Spanish does not have the English v. The letters b and v represent one single sound, and 'baca' and 'vaca' are pronounced identically. That one sound has two versions depending on where it sits: a full closure like an English b at the start of a phrase or after m or n, and a much softer version between vowels where your lips barely come together.
The letters are not the point
In English, b and v are two separate sounds, and mixing them up changes words: 'boat' and 'vote', 'berry' and 'very'. English speakers therefore assume the Spanish letters do the same job.
They do not. Spanish spelling keeps b and v apart for historical reasons only. A Spanish speaker reading 'vaca' and 'baca' aloud produces the same thing. This is why spelling errors between b and v are extremely common among native writers — there is no sound to guide them.
So the first thing to stop doing is deliberately making an English v when you see the letter v. Putting your top teeth on your lower lip for 'vida' or 'nueve' adds a consonant Spanish does not use.
Version one: the hard b
At the start of an utterance, and after m or n, the sound is a full stop: both lips close completely, pressure builds, and the closure releases. That is an ordinary English b.
'Boca' at the start of a sentence, 'bien', 'vamos' at the start of a sentence, 'hombre', 'un vaso'. All of these get the full closure.
Nothing to learn here — you already make this sound. Just accept that words spelled with v get it too.
The trigger is the pause, not the letter. 'Vamos' at the start of a sentence has a full closure; the same word in the middle of a phrase, with a vowel in front of it, does not. So the same word can begin with either version depending on what came before it, which is why it is worth practising short phrases rather than words in isolation.
Version two: the soft one, between vowels
This is the version English speakers miss, and it is by far the more common of the two in running speech.
When the sound falls between vowels — inside a word, or across a word boundary — the lips do not close. They come near each other and let air keep flowing through the gap, producing a soft buzz. 'Saber', 'nueve', 'la boca', 'la vida'.
To find it: say a long English 'b' and then, without stopping the sound, ease the pressure until your lips separate slightly and air escapes. The result is soft, continuous, and faintly buzzy.
Crucially, it uses both lips. The English v uses teeth and lip. If your top teeth touch your bottom lip at any point, you have made the wrong sound. A physical check: say 'saber' with a finger held lightly across your lips — you should feel both lips moving toward each other, and no tooth contact at all.
Getting this soft version right does more for how Spanish you sound than almost any other single consonant, because b and v are everywhere and the hard closure in the middle of a word sounds heavy and over-articulated.
The same pattern applies to d and g
Once you see it, b/v is part of a bigger system. Spanish d and g behave the same way: hard at the start, soft between vowels.
Between vowels, d relaxes toward the th of English 'this' — 'nada' comes out close to 'na-tha', and 'usted' ends on something barely there. Between vowels, g relaxes into a soft continuous sound with no closure — 'agua', 'lugar'.
English keeps its stops fully closed everywhere, which is why English speakers sound percussive in Spanish: every b, d, and g lands with a thud. Softening all three between vowels is one habit, learned once, that changes hundreds of words.
Drill them together: saber, nada, agua. Same rule, three consonants.
What to listen for
Record 'boca' and 'saber' back to back. In 'boca' your lips should close completely. In 'saber' they should not. If both sound the same, you are applying the hard version everywhere — the most common English-speaker pattern.
Then record 'vida' and check for tooth contact. Slow it down and watch in a mirror. Teeth on lip means English v.
A third check for the over-corrector: some learners get so attached to the soft version that they use it at the start of sentences too, which sounds mushy. 'Bien' at the start of a sentence needs the full closure.

Questions
Do Spanish speakers really pronounce b and v the same?+
Yes. The distinction does not exist in the sound system. Some speakers will produce a teeth-and-lip v when reading very carefully, or when spelling something out to distinguish the letters, but it is not part of normal speech.
How do Spanish speakers know which letter to write?+
They memorise it, the same way English speakers memorise which words take 'ph'. Confusing b and v is one of the most common native spelling errors, precisely because there is no sound to fall back on.
What is 'be larga' and 've corta'?+
They are names for the two letters, used when spelling out loud — long b and short v, with regional variants like 'be grande' and 've chica'. They name the letters, not two different sounds.
Will using an English v make me hard to understand?+
Not usually — context carries it. But it is one of the clearest signals of an English accent, and it is unusually easy to fix, because you are removing a sound rather than learning a new one.
