Yes, texting in a language improves your speaking, but only part of it. It trains the part where you find the words and put a sentence together, and it lets you do that with a few seconds to think. It does not train your pronunciation or how fast you understand someone who is talking to you, so pair it with something that does.
That is the honest answer. The rest of this post is why I still put chat at the centre.
How I learned English by typing
When I was a kid, I learned English playing an online video game, on a server where everyone wrote in English.
I had a Spanish-English dictionary next to the keyboard. Paper. I looked words up, typed something, probably said something ridiculous, and kept playing.
Notice what I was doing: typing. Not speaking.
And still, after that summer, English stopped feeling like a school subject. The words came when I needed them. Years of classes had given me the words. Typing to people who answered made them reachable.
Does writing improve your speaking?
Think about what speaking actually asks of you. You have to understand what the other person said. You have to find the words. You have to put them in an order that works. Then you have to say them out loud, at the speed of a conversation.
Texting covers the middle of that list very well. You read the other person's message, you go looking for words nobody handed you, and you build a sentence that has to make sense to someone else. That is the expensive part. It is also the part I felt go first with my Italian: first a few words, then mentally translating sentences I used to say without thinking.
There is research behind this, and I want to be careful not to oversell it.
Psychologists call it retrieval practice: pulling something out of memory makes it easier to pull out the next time, more than reading it again does. Every message you write is a small retrieval. You are not recognising words on a page, you are producing them.
The linguist Merrill Swain made a related point decades ago: when you have to produce the language, you notice what you cannot say yet. You reach for a word, it is not there, and now you know.
And there is at least one classroom study on chat and speaking specifically. Payne and Whitney had one group of language students spend two of their four weekly class hours in a text chat room, and that group did better on a speaking test than a comparison group that did not. It is one study, not a law of nature, but it points the same way.
So, does writing improve your speaking? It improves the part of speaking that happens in your head. Which is a big part of it.
What texting does not train
Now the other side, because it matters.
Texting does not train your mouth. Your accent, the rhythm, the sounds your own language does not have: none of that gets practice when you type.
It does not train your ear either. Reading a message at your own pace is not the same as understanding someone who talks fast, drops half the syllables and does not wait for you.
And it does not train timing. In a real conversation the silence gets awkward fast. In a chat you can take a minute. That is why chat is easier to start, and also why it is not the whole thing.
So if your goal is to sound natural out loud, texting alone will not get you there. It gets you the words and the sentences. You still need to listen and to say things out loud.
How to practise speaking a language without a partner
You can do most of this by yourself. Here is the routine I would suggest, with chat in the middle and the rest around it.
Text with something that answers. A friend who speaks the language, a language exchange partner, a tutor who is happy to chat between sessions, or an AI. The key word is answers. A reply uses words you did not choose, asks you something you did not plan for, and makes you write again. A journal does not do that.
Say your message out loud before you send it. This takes five seconds and it turns typing into speaking practice. You already built the sentence, so now your mouth gets a turn. If you feel silly doing it, that is normal. Do it anyway.
Send a voice note sometimes. If whoever you text accepts voice notes, use them. You will hear yourself hesitate, which is useful information.
Talk to yourself. Describe what you are cooking, complain about the traffic, rehearse what you would say to a waiter. Nobody corrects you, but your mouth gets used to the sounds.
Listen most days. Podcasts, series, radio, anything you actually enjoy. This is the part that trains your ear, and texting cannot do it for you.
Speak with a person when you can. Once a week with a tutor, a class or an exchange partner is plenty if the rest of the week is busy. Bring the things you got stuck on while texting. Those are your real questions.
Small and often beats big and rare here. Ten minutes of texting most days tends to keep the words closer than one long session on Sunday. There is more on that in is 15 minutes a day enough.
How to practise speaking a language with AI
You can do this with a general AI chatbot, and it works. Tell it your level, ask it to stay in the language, to correct you by saying your sentence back properly, and to end each message with a question. I wrote a whole post on setting up an AI chatbot for practice, including where it fits better than Parla.
The catch is usually not the AI. It is you: you decide when to open it, you decide what to talk about, and you set it up again each time. On a good week, easy. On a week when work eats your evenings, maybe not.
Why I built Parla around chat
I spent a year in Italy and learned Italian there. Then I moved away and it started slipping. Not because I stopped caring. Because I had nobody to speak it with.
I did not want another course. I wanted someone to text when I had five minutes.
So that is what Parla is. You pick a companion who has a city, a job and a week of her own, and you text her on Telegram, in her language, when it suits you. The card at the end of this post lists the languages you can pick from. She corrects you by rephrasing what you said, inside her reply, and carries on talking, the way a friend would. You can type or send a voice note, and she answers in writing or, now and then, with a voice note of her own (more on why she sends voice notes).
On Sunday she sends you a letter, with a PDF, that counts your week: how many days you wrote, which old words came back, and the two things to work on. If you have a tutor, that letter is a pretty good thing to bring to your next session.
Some honest limits. She is an AI, and she says so in her first message. Her corrections are suggestions, and sometimes she is wrong. She will not fix your accent, so keep listening and keep saying things out loud. And if you are a complete beginner, start with a course or a tutor first: Parla works from roughly A2, when you can already hold a simple conversation.
It costs 20 euro a month, 99 euro every six months, or 149 euro a year (12.42 euro a month), VAT included. You get the first week free, and you do not need a card for it.
Texting is not the whole of speaking. But it is the part you can actually do on a damn Tuesday, in the queue at the supermarket, and it is the part that keeps the words from disappearing.
So here is my suggestion. Text her for the free week and notice whether the words come a bit quicker by day seven.
If they don't, it cost you nothing to find out.
