Learn a language through conversation: Spanish, French and German with an AI character

Sophie has spent two years collecting points in a Spanish learning app. She knows the names of all the fruit, can conjugate “ser” in her sleep and has a streak a marathon runner would be proud of. Then, in Seville, a waiter asks her something perfectly ordinary and her mind goes completely blank. Anyone who has learnt a language from a textbook knows that moment: the words are there, but they refuse to turn into a conversation.

You learn to talk by talking. The problem is that there is not always someone to talk to, and the first attempts with a real person can be stressful. This is where an AI character comes in handy: patient, available at any hour and never judgemental when you get the gender of a noun wrong for the third time.

We have already written about how chatting with a chatbot breaks the language barrier for people learning English. This time the focus is on learning a language through conversation with an AI character in Spanish, French and German, although the same methods work just as well with Italian, Portuguese or Dutch.

How it works in practice

The rule is simple: a character on CandysAI replies in the language you write in. You write in German, you get a reply in German. Switch to Spanish and the conversation switches with you. There is nothing to change in the settings.

It is best to start with a short agreement in English and then move into the language you are learning. For example:

“I’m learning German, roughly at A2 level. From my next message I’ll write in German. Keep your replies short and use simple sentences. At the end of each reply, correct at most two of my mistakes and explain them in one sentence in English.”

A message like this sorts out three things at once: the character knows your level, how long the replies should be and how you want to receive corrections. The character can also remember that you are learning a language and come back to it over the following days, for example by asking how your lesson went. You can always check what it has remembered and delete it.

Corrections that do not put you off

The biggest enemy of conversation in a foreign language is fear of making mistakes. If every message comes back covered in red ink, after three days you will not feel like writing at all. That is why it pays to agree with the character on how it should correct you.

• Two mistakes per message, at most. The ones that get most in the way of understanding, not every typo.
• Corrections at the end, not in the middle. First a normal reply to what you wrote, then a short note. The conversation does not turn into a dictation.
• The correct sentence in full. A ready-made pattern is easier to remember than a rule.

Here is an example from German. You write: “Gestern ich bin ins Kino gegangen”. The character replies about the film and adds at the end: “A small correction: Gestern bin ich ins Kino gegangen. When a sentence starts with ‘gestern’, the verb moves to second place.” One sentence, no lecture, and German word order slowly starts to sink in.

If you like more intensive practice, you can change the deal: “Today correct everything, even the little things. I want to see how many mistakes I make.” Or the opposite: “No corrections today, I just want to chat.” Both modes are fine. What matters is that it is your choice.

Real-life scenes: café, doctor, market

Casual chat is one thing, but when you travel or live abroad, specific situations are what really count. A character can step into them like an actor in an improv scene. All you need to do is describe the scene and the roles.

At a café in Spanish

“Let’s act out a scene in Spanish. You’re a waitress in a small café in Madrid and I’m a customer. Speak naturally, but not too fast.”

The character will greet you and ask what you would like, and you practise phrases such as “¿Me pone un café con leche, por favor?” and asking for the bill. If you would like someone with a bit of Madrid character in the background, you could chat with Liora Swift, a Spanish detective from Madrid. Just remember that she is a character with her own story, not a teacher, so you need to ask her for lesson mode.

At the doctor’s in German

A visit to the doctor in a foreign language is stressful even for people who otherwise speak quite well. It is worth rehearsing beforehand:

“You’re a GP in Munich. I’ve come in because I’ve had a sore throat for three days. Ask me the questions a doctor would ask.”

Sentences such as “Ich habe seit drei Tagen Halsschmerzen” will come in handy, along with questions about medicines or a sick note. This is language practice, not medical advice: always discuss real symptoms with a real doctor.

At a market in French

“You’re a stallholder at a market in Lyon. I want to buy some fruit and cheese, but I don’t know the names of everything. Help me out if I get stuck.”

“Je voudrais un demi-kilo de pêches” or “Combien coûte ce fromage ?” are sentences that genuinely come in useful on holiday. After the scene, ask the character for a recap: which phrases came up and which ones are worth remembering.

A word list and revision

New words from a conversation slip away easily. That is why it is worth asking for a short list at the end of each session:

“List five new words or phrases from today’s conversation, with a translation and one example sentence each.”

Copy the list into a notebook or the notes on your phone. Writing things down by hand helps you remember them, and you end up with your own word list built from things you actually talk about, rather than from a chapter on office furniture.

Reminders are handy for revision. Just write: “Remind me tomorrow at 7 pm to revise today’s words” or “remind me on Saturday at 10 that it’s quiz time”, and the character will message you at that time. You can start the next conversation with a mini quiz: “Ask me five questions about yesterday’s words, I’ll answer in Spanish.”

Tips for every level

Beginners (A1–A2). Ask for short sentences and simple words. Do not be embarrassed about mixing languages: “Ich möchte… how do you say ‘book a table’?” is perfectly fine. Conversations about everyday things work well: what you are eating, how your day went, what the weather is like. When you do not understand something, write: “Say it more simply.”

Intermediate (B1–B2). This is the time for telling stories and giving opinions. Ask the character to use open questions and to ask for details. Rephrasing is another good exercise: “Rewrite my sentence the way a native speaker would say it.” You will see the difference between correct and natural.

Advanced (C1 and above). Practise register and nuance: the same e-mail once formally and once casually. Discuss films, books and news from the country whose language you are practising. Ask for idioms and slang, but check them in a dictionary, because everyday language changes quickly.

To be honest: what an AI character cannot replace

Chatting with a character is excellent practice, but it has its limits, and it is worth knowing them.

• AI makes mistakes too. A language model usually writes correctly, but it can miss an error, explain a rule badly or suggest a phrase that sounds unnatural. Check important grammar rules in a textbook or dictionary.
• It is not a certified course. A character will not prepare you systematically for an exam, give you an official level assessment or issue a certificate. It complements a course, lessons or an app rather than replacing them.
• The chat is text-based. You practise writing, reading, vocabulary and sentence building. Pronunciation and listening need to be learnt elsewhere: from podcasts, films and lessons with a real person.
• Real people are irreplaceable. The goal is a conversation with the waiter in Seville, the neighbour in Berlin or a colleague in Lyon. A character helps you prepare for it and take the edge off the nerves.

For people who live abroad, a foreign language is part of everyday life, while their own language gives them a breather. We wrote about that other side in our article on living abroad and missing conversation in your own language.

Summary

Learning a language through conversation with an AI character works best when it is regular, short and set up on your terms: your level, how you want to be corrected, real-life scenes and a word list at the end. Fifteen minutes a day in Spanish, French or German does more than two hours once a month. If you want to give it a try, write one sentence today to a character in the language you are learning and ask them to reply in the same language.
