How to pronounce the Spanish J
The Spanish j is a scraping sound made at the back of the mouth: raise the back of your tongue toward the roof as if to say 'k', but leave a gap so the air rasps through instead of stopping. It is rougher and noisier than an English h. The same sound is spelled g before e and i — which is why gente and rojo share a consonant.
English speakers breathe on the wrong letter
Two habits have to flip at once.
The letter h in Spanish is completely silent. 'Hola' begins on the vowel. 'Hijo', 'hacer', 'hora' — nothing at the start, not even a small puff. English speakers reliably add a breath there because the letter looks like it should do something.
The letter j is the opposite: it is a strong, audible friction sound, considerably more forceful than the English h in 'hat'. English speakers reliably under-do it, producing a soft breathy h that sounds weak.
Flip both. h is nothing. j is friction.
How to make the sound
Say 'k' and hold the position just before you release it. The back of your tongue is pressed against the back of the roof of your mouth, blocking all the air.
Now lower the tongue by a hair — just enough to open a narrow channel — and push air through it steadily. You get a rough, scraping hiss. That is the Spanish j.
The two things to control are position and force. Position: it happens at the back, near the k contact, not in the throat and not at the front of the mouth. Force: push enough air that the sound is clearly noisy. A gentle version disappears in normal speech.
If you know the German 'Buch' or the Scottish 'loch', the Spanish j is made in the same region. If you do not, the k-and-release drill is the fastest route in. Hold the sound for three seconds on its own before you try to put it in a word — most learners fail because they attempt it inside 'rojo' before they can make it at all.
How rough it comes out varies from speaker to speaker and place to place, from a light breath to a heavy scrape. Aim for the middle: clearly audible friction, no strain.
Which spellings take it
The letter j always: rojo, trabajo, jugar, caja, hijo.
The letter g before e or i: gente, general, gigante, elegir. Before a, o, or u, the same letter is a normal hard g instead — gato, gota, gustar — which is why 'gente' and 'gato' start with different sounds despite the same letter.
And a small set of names and words keep an old spelling with x: México, Oaxaca, Texas. The x there is the j sound, not a ks.
The practical consequence is that you cannot read g on sight. Look at the vowel after it first.
Spanish works around the problem when it needs a hard g before e or i by writing gue and gui, as in guerra and guitarra, where the u is a spelling device and is not pronounced. That is worth knowing early, because it removes most of the guesswork from reading aloud.
Words to practise
Start where the j is between vowels and stressed, because that is the easiest place to hold it long.
**rojo** (red) — a j in the middle plus a tapped r at the front. Two Spanish-specific sounds in four letters.
**trabajo** (work, job) — a longer word so you cannot rush the j; keep the friction going through the whole consonant.
**gente** (people) — the g spelling, so the eye fights you. Say it ten times to break the reflex to say a hard g.
**hijo** (son) — silent h at the front, strong j in the middle. This one word drills both halves of the flip.
Then pair them with h-words to keep the contrast alive: hola / rojo, hacer / trabajo. Say them alternately until the h stays empty and the j stays noisy.
What to listen for
Record 'hola' and check the first tenth of a second. There should be nothing there — the recording begins on the vowel. Any breath at all and the English habit is still running.
Record 'rojo' and listen to the middle. You should hear texture: a noisy, grainy consonant, not a soft gap between two vowels. If the j is inaudible on playback, push more air.
Check the placement by feel. Put a hand flat on your throat while you say the j. There should be no vibration during the consonant itself — it is voiceless — and the point of friction should feel like it is behind your tongue, high up, not down in your throat.
In TonePerfect, the j and the vowels around it are scored as separate sounds and ranked weakest-first, so a j that is really an English h usually shows up near the bottom of the ranking.

Questions
Is the Spanish j the same as the English h?+
No. The English h is a light breath made with the vocal tract mostly open. The Spanish j is real friction made by narrowing the passage at the back of the mouth. They occupy similar territory, which is why 'rough h' is a useful first approximation, but the Spanish sound is noisier.
When is g pronounced like j?+
Before e and i: gente, gigante, elegir. Before a, o and u the same letter is a hard g instead: gato, gota, gustar. So you can never read a g on sight — check the vowel that follows it first.
Is the h ever pronounced?+
In native vocabulary, no — it is silent everywhere. The combination ch is a separate thing entirely, the sound in 'mucho'. A few recent loanwords are the only place you may hear a breathy h, and even then it varies by speaker.
Why does the j sound harsher in some accents?+
How much friction the sound carries varies from region to region and speaker to speaker, ranging from a light breath to a heavy rasp. All of it is normal Spanish. Pick the version of the sound you hear in the accent you are learning from and match that.
