You freeze up when speaking English because you don't practice enough. It's that simple. AI solves this by being a conversation partner available 24/7, without judgment, that corrects you on the spot. Here, I show you 5 ways to practice conversation with AI — voice speaking, shadowing, talking to yourself, role-play, and using chat as a bridge — and how to combine all this with real conversations with a native speaker.
Look, speaking is the fear of 10 out of 10 students. It gives you chills just to think about it, right? You worry about making mistakes, what the other person will think, if you'll freeze in the middle of a sentence. I get it. I've been there with Italian, Spanish, and French — every new language starts like this.
And the truth is, I always ask the same question to those who tell me they're stuck: how many times a week do you speak English? Almost always, the answer is the same: "Well, I don't practice speaking." So there it is. You will only improve your speaking if you practice. There’s no other way. And until 2022, this was a tough problem to solve — unless you had the time and money to pay for private lessons every day or lived abroad.
Now there’s a new way: talking with AI. And it’s not a passing trend — it’s the most consistent way to practice speaking that I’ve seen in 15 years of language learning. In this post, I’ll show you 5 ways to practice English conversation with AI, how to combine this with what I already teach in videos (shadowing, talking to yourself, language exchange), and what to expect at each stage. Lanna is a Brazilian language learning platform with AI built exactly around this.
Why do Brazilians freeze up when speaking English?
We freeze up because we hardly practice active production — we only consume content. We listen to music, watch series, do multiple-choice exercises, read texts. All of this is input. It’s important, but it doesn’t unlock your speaking. To unlock it, you have to produce — speak and write.
And then there's the other side, which is fear. You sit there feeling that chill just thinking about speaking with someone. You think, "What if I make a mistake?", "What if that person laughs?", "What if I don’t understand what they said back?" This is what Stephen Krashen called the 'affective filter' — the emotional filter that rises when you’re anxious and blocks acquisition.
So the problem is twofold: lack of practice and fear of making mistakes in front of others. Both can be solved if you have a conversation partner who (1) is available every day, (2) doesn’t judge you, and (3) corrects you without drama. No human does that. AI does.
Why does AI work so well for conversation?
Because it eliminates the emotional filter. You can make mistakes at will, freeze, ask it to repeat 5 times, start a sentence, give up halfway, restart — AI simply responds, without a frown, without a short time limit, without pressure. It's the exact opposite of an expensive private lesson where you feel like every minute counts and you have to perform.
There are three things that AI does better than any other method for conversation:
- Total availability: 6 AM, midnight, during lunch break. It doesn’t matter. It’s there.
- Volume without cost: you can have 10 conversations of 5 minutes each day if you want. No human teacher can deliver that.
- Immediate feedback: you speak, it understands immediately, processes, and responds with natural voice in less than 2 seconds. And if you want correction, it tells you exactly what you got wrong and why.
What AI does not do is replicate the real spontaneity of a human. This is important, and I’ll come back to this point later. But as a tool for unlocking and gaining practice volume, it’s unbeatable.
5 Ways to Practice Conversation with AI
It’s not just about "opening ChatGPT and speaking". There are 5 different ways, each training something different. Ideally, you should rotate between them throughout the week.
1. Voice speaking mode — real-time conversation
This is the main one. You open the speaking mode, choose a topic, and have a real conversation. You speak, AI understands, responds, you reply, and the cycle continues. No record button, no waiting 10 seconds for a response, no transcription appearing on the screen — just the conversation flowing.
A tip I always give: start with topics you already know. Your routine, your job, what you had for breakfast, what you did over the weekend. Don’t start talking about politics or quantum physics — you don’t know the vocabulary even in Portuguese. Known topics = you focus on the language, not the content.
2. Shadowing with AI-generated audio
Shadowing is a technique I explain in the videos — it’s when you imitate exactly what the other person is saying, in their rhythm, in their pronunciation. Normally, we do this with YouTube videos or podcasts. But you can also do it with AI-generated audio.
How it works: you ask AI to generate a sentence in English at your level, it speaks with a natural voice, you pause and repeat imitating the exact sound. Repeat each sentence 3 or 5 times until you feel comfortable. The advantage over YouTube videos is that you control the level — if it’s too hard, ask for something easier. If it’s too easy, ask for something more complex. Never go over 5 minutes per session — long shadowing sessions are tiring and become automatic without learning.
3. Talking to yourself using AI as a prompt for questions
I know, talking to yourself seems crazy. But practically every polyglot does this. It’s the most used technique by those at an advanced level. And there’s a turbocharged version with AI that’s even better: instead of coming up with questions for yourself, ask AI to generate 10 questions about a topic and you answer orally, one by one, at your own pace.
Example prompt:
Ask me 10 simple questions in English about my work routine. One question at a time. Wait for me to answer before moving on to the next. Correct my mistakes at the end of each answer.
This transforms "talking to yourself" into "talking with a patient teacher who only asks questions". It works incredibly well for those who are still shy about speaking with another person.
4. Role-play of a real scenario
Here, you ask AI to simulate a specific situation. Job interview, restaurant service, conversation at the airport, work meeting, first date with someone. AI plays the role, you respond in character as well, and you both carry out the situation to the end.
This is the method that most closely resembles what you’ll face in real life. And it has a huge advantage: you can make mistakes without consequences. If you mess up in the interview simulation, ask it to restart and try again. It’s like a flight simulator — you mess up, reset, try again without crashing.
5. Text chat as a bridge to voice
When speaking is too difficult and you freeze too much, text chat is a bridge, not a destination. The idea is: write the sentence in the chat, review it, read it aloud (standing up if you can, to engage your body more), and only then go back to voice mode. The text gives you time to think, and the audio afterwards forces you to produce orally what you’ve already formulated.
This works especially well for those at A2/B1 who still can’t maintain a fluid conversation just verbally. But remember — it’s a bridge. If you stick only to text, you’ll never unlock your speaking. Use it as a ramp, not as an excuse.
How to combine AI with real conversation with a native speaker
AI does not replace a native speaker. AI prepares you to face a native speaker without panic. They both train different skills, and the combination is much stronger than just one.
The language exchange with a native online — via HelloTalk, Tandem, Italki — remains essential. A native gives you what AI doesn’t provide:
- Real street slang (AI tends to use "book English")
- Genuine emotional reactions (smiles, frowns, awkward silences)
- Varied accents and imperfect fast speech
- Cultural context — references from series, music, jokes, politics
- Extra motivation from having a friend waiting on the other side
The ideal combination, in my experience: AI every day (15-20 min) + native speaker 1 to 2 times a week (30-60 min). AI gives you volume and confidence. The native speaker gives you reality and spontaneity. Those who only do AI end up with "too polished" speech. Those who only do native don’t have enough practice volume. Those who do both unlock faster.
How much time per day and when will you notice a difference?
15 to 20 minutes a day, every day, is more than enough. What counts here is consistency, not session duration. I always say this in videos and I’ll repeat: 15 minutes every day yields much more than 2 hours once a week. Always. No exceptions.
The realistic evolution timeline:
- Week 1-2: embarrassment about speaking even with AI. You freeze, forget words, speak incomplete sentences. Normal. Keep going.
- Week 3-4: start to find sentences faster. You still freeze, but notice that you unlock yourself in a few seconds.
- Month 2: manage to have a 5-minute conversation on a known topic without pausing too much. Pronunciation starts to visibly improve.
- Month 3: fluid 10-minute conversation on a known topic. Start to manage to speak on unknown topics with effort.
- Month 6: speak on any topic from your daily life. Scratch the B2 (upper-intermediate) level in speaking.
These timelines apply to those at A2/B1 starting out. If you are a complete beginner (A1) or already an intermediate who’s stuck, adjust mentally to slower or faster.
Most common mistakes when practicing with AI
The number 1 mistake is using AI just to ask for translations. You open ChatGPT, ask "how do you say X in English?", it answers, and you close it. This is using AI as a dictionary — it’s not practicing conversation. To practice, you have to talk, not ask.
Other mistakes I see a lot:
- Only using text. Chat is a bridge, not a destination. If you only read and write, you’ll never unlock your speaking.
- Wanting too difficult topics at the beginning. "I’m going to practice talking about international politics." Wrong. Start with your routine.
- Not repeating. Did that sentence you tried sound good? Repeat it 3 times in the same turn to cement it. Rhythmic repetition is what turns active production into automatic.
- Asking for correction too much. At the beginning, you don’t need to be corrected in every sentence — you need to talk. Let AI interrupt only when the mistake is severe. Excessive correction kills fluency.
- Skipping days. If you skip 1 day, return the next. If you skip 3, you’ll notice. If you skip 7, you basically started over.
Frequently Asked Questions
Can I practice English conversation only with AI?
Yes, and it works very well to unlock your speaking. But ideally, combine AI practice every day with a native speaker once or twice a week. Each trains a different part.
How much time per day?
15 to 20 minutes, every day. Consistency wins over duration. In 4 to 6 weeks you’ll feel your speech is less blocked. In 3 months, you can manage a basic 10-minute conversation.
What’s the difference between AI and shadowing?
Shadowing is imitating existing audio (pronunciation and rhythm). AI is free conversation (active production). Both train different skills. Do both.
Does AI replace conversation with a native speaker?
No. It complements. A native provides cultural context and spontaneity. AI provides volume and confidence. Those who do both learn faster.
Do I need a minimum level to start?
No. Even A1 can start. AI adapts to your level and can repeat in Portuguese when you don’t understand. Start with a known topic.
What if I freeze in the middle of the conversation?
Ask AI to repeat slowly, rephrase more simply, or translate the word. It doesn’t judge and isn’t in a hurry. That’s exactly why it works so well.
Why use an app instead of ChatGPT?
ChatGPT is generalist. Apps like Lanna combine voice speaking, shadowing, grammatical correction, and progress history in one flow. More results per hour of study.
So, how to start today?
If you’ve made it this far, the next step is simple: open Lanna’s speaking mode now and talk about what you did today. 5 minutes. No preparation. Just open and speak. You’ll make mistakes, freeze, and laugh at your own pronunciation. Normal. That’s how it starts.
Do it again tomorrow. And the day after that too. In 2 weeks, you’ll notice a difference. In 2 months, you won’t recognize the stuck student you were before. I promise — I’ve seen this happen hundreds of times.
Lanna has 8 study modes, including real-time voice speaking, shadowing with AI-generated audio, role-play scenarios, and text chat — all integrated into the same flow.
