Spoken French is not written French said out loud. It is a different grammar, with different question forms, a different first person plural, and a negation with one half missing, and a learner who was taught the written system produces sentences that are correct and that nobody says. Worse, they cannot understand the reply, because the reply is in the other system.
So the first move is not more vocabulary or another tense. It is to learn the spoken forms as the primary ones and to file the written versions where they belong, which is on paper.
The decision, and five words that keep a conversation alive
- tu and vous. Informal singular against formal or plural, and using tu to a stranger in a shop is a real error rather than a small one. Wait to be invited.
- Bonjour, madame. The greeting is not optional in France and is expected on entering any shop. Leaving it out reads as rudeness rather than as shyness.
- Voilà, there it is, used to close a thought, hand something over, or fill the gap at the end of an explanation.
- Du coup, so or therefore, which opens perhaps a third of spoken sentences among younger speakers.
- Enfin, well, or rather, used to correct yourself mid sentence without stopping.
- Ça marche, that works, the ordinary way to agree to a plan.
Four differences that cover most of it
Nobody says nous in conversation. The subject that covers a group including yourself is on, taking a third person singular verb, so on va rather than nous allons, and the nous forms you spent a term conjugating turn up in writing and in speeches. The negation loses its first half: je sais pas, c'est pas grave, and keeping the ne in a relaxed conversation marks you as somebody reciting.
Questions are the third and the largest. Inversion, the form every textbook opens with, belongs to writing and to formal speech. In conversation a question is a statement with a rising tone, or it puts the question word at the end: tu vas ou rather than ou vas-tu. And the fourth is contraction, which is not laziness but the normal form: t'es, y a, j'sais pas, chuis. Those four cover a large share of the distance between the French you were taught and the French in the room.
The learner who still says nous
Here is the stall and it is entirely a teaching artefact. A course teaches the six person conjugation, so nous gets a sixth of the practice, and a learner arrives with it automatic. They then use it for years, are understood perfectly, and are marked in every sentence as somebody who learned French rather than picked it up.
The receiving half is the expensive one. Because on was taught as the impersonal one, a learner hears on y va and parses it as one goes there, which is not what was said, and the subject of the sentence is lost. That happens dozens of times in a conversation, and it feels like a vocabulary gap rather than what it is. The correction takes a week and is mechanical: use on for the first person plural everywhere in speech, and hear it that way by default rather than as an impersonal one.
Three ways to ask
The same question, from a kitchen to a written report
All three are correct French. Choosing the wrong end for the situation is what makes a fluent learner sound strange.
Placed by where each form is normally heard, from relaxed conversation to writing. The placings are this page's judgement.
- Tu vas ouStatement order, question word at the end, tone doing the work
- Ou tu vasQuestion word in front, and still no inversion
- Ou est-ce que tu vasNeutral, safe everywhere, and slightly long
- Ou vas-tuInversion. Correct, and the first form every course teaches
The rail runs the opposite way from the syllabus, which starts at the formal end because it is the tidiest to explain. A learner therefore arrives with the one form that is rarest in speech.
Two ways to get the spoken version
A model will produce the spoken form if you ask for it, and this is the one job where it is genuinely useful in 2026. Write your sentence, then ask what a French person would say in a relaxed conversation, and ask it to keep the meaning and change the register. It replaced needing a native speaker present to tell you that your correct sentence is not one anybody uses. Free at the level this needs. The limitation is specific and worth remembering: models are trained mostly on written French and drift back towards it, so the instruction has to be repeated and the answer checked, and it will never tell you that a form is regional unless you ask.
For the other half, which is somebody to try it on, Tandem is free and full of French speakers who want English. It replaced the pen pal and the classifieds, and the thing to do differently from most exchanges is to ask explicitly to be corrected on register rather than on grammar, because your grammar is probably fine and your register is the problem. Most partners will correct grammar by reflex and never mention that nobody says the sentence.
The mistake: choosing tu and vous from a rule
The rule you were given is about age and formality and it is not wrong so much as unusable, because the real determinant is what the other person has already done and what the setting is. The cost is asymmetric: vous where tu was expected is slightly stiff and forgotten in a minute, and tu where vous was expected is a small social event.
What native speakers actually do is listen to the first two sentences and match. If somebody says vous, say vous. If a colleague of your age uses tu, use tu back. In the very few genuinely ambiguous cases the question on peut se tutoyer exists precisely because native speakers need it too, and asking it is normal rather than an admission of anything. The rule to carry is simpler than the one in the book: start with vous with any stranger over about twenty five, and switch when they do.
What speaking cannot settle on its own
The four differences above are also why French sounds unrelated to its own spelling in a conversation, since contraction and elision are what erase the word boundaries, and following that in real time is why written French and spoken French sound unrelated. The written system is still worth having, because it is what an email and an exam are marked against, and the split between the two is the argument in gender, agreement, and the tenses that carry the language. Producing any of this at conversational speed depends on the sounds arriving right, which is nasal vowels, silent endings, and liaison. And if there is nobody to try it on, the arrangement that makes an hour worth its price is finding someone to speak to, and what to do in the hour.
