Immersion alone isn’t enough to learn Mandarin, and neither is a conversation partner alone. Not even if all you want is to understand people and talk back. Both give you real Mandarin, which you need. Neither gives each new word the repetitions it takes to stick, or keeps your older words alive. For that you need a system.
Here are the four things learning to speak takes, and which ones each approach covers.
The four things you need
| What it means | Immersion | A tutor or language partner | A review system | |
|---|---|---|---|---|
| 1. Real input | Hearing lots of real, everyday Mandarin | Yes | Some | No |
| 2. Speaking | Saying what you mean, out loud, to someone | Sometimes | Yes | No |
| 3. A steady inflow of new words | A few new words every day, every day | By chance | By chance | Yes |
| 4. Keeping old words alive | Meeting each word again before you forget it | By chance | By chance | Yes |
Immersion and a tutor are strong on the first two. The last two are where people stall, and they’re the ones nobody talks about.
Why immersion alone stalls
Say you’re living in China, or you’ve got a Chinese partner, and you’re invited to dinner at a friend’s place. Here’s how it starts, from Mandarin Hero’s Dinner with friends lesson:
来啦！快进来坐。 Lái la! Kuài jìnlai zuò. — You made it! Come on in. 好香啊！在做什么呢？ Hǎo xiāng a! Zài zuò shénme ne? — That smells great! What are you making? 西红柿炒鸡蛋，还有土豆烧牛肉。 Xīhóngshì chǎo jīdàn, hái yǒu tǔdòu shāo niúròu. — Tomato and egg stir-fry, and beef stewed with potatoes. 好啊，你帮我把土豆削个皮吧。 Hǎo a, nǐ bāng wǒ bǎ tǔdòu xiāo ge pí ba. — Sure. Could you peel the potatoes for me?
Great evening, lots of real Mandarin. But 削皮 (xiāo pí, to peel) comes by once. When will you hear it again? Maybe next month, maybe in half a year. By then it’s gone.
That’s the problem with learning only from what comes your way. A handful of words, like 好 (hǎo, good) and 什么 (shénme, what), you hear every day. Most of the words you need come by rarely, and a word you’ve met once isn’t a word you know.
How many times do you need to meet a word? There’s no single number, but the research gives a clear picture:
- Webb (2007) found that learners picked up a substantial part of a new word’s meaning and use after meeting it around ten times in context, and that knowing it fully can take more.
- A 2019 meta-analysis by Uchihara, Webb and Yanagisawa confirmed that more encounters mean more learning. Across studies, estimates of how many it takes range from about 6 to more than 20.
- In Waring and Takaki (2003), learners read a graded reader with 25 target words. Three months later they remembered, on average, the meaning of about one of the 25. Words they’d met fewer than eight times were gone.
So you’d need to hear 削皮 ten-odd times, ideally spread out, before it’s yours. Immersion might get you there in a year. Or never.
Why a conversation partner alone stalls too
A tutor or language partner fixes the speaking part. You talk, they correct you, you learn what people really say. Keep doing that.
But look at the numbers. In an hour you might meet twenty new words. Next week your tutor won’t remember to bring back all twenty, let alone the ones from three weeks ago. A good partner also, without meaning to, sticks to words you already know so the conversation flows. That’s comfortable, and it’s why many learners plateau at “can chat about the same five topics”.
Your tutor’s job is the conversation. Keeping track of which of your hundreds of words is about to slip away isn’t something a person can do. A system can.
What a system does: steady in, nothing lost
3. A steady inflow of new words. Progress in a language is mostly vocabulary, and it adds up quietly. Ten new words a day is 300 a month and over 3,500 a year. Five a day is still more than 1,800 a year. Skip a week and nothing breaks, but stop for months and you stop moving. The point isn’t a big number, it’s that it never runs dry.
4. Keeping old words alive. Every word you add needs to come back: the next day, a few days later, a week, a month. Each time just before you’d forget it, so recalling it still takes a little effort. That’s spaced repetition, and it’s how one review system can give every word its ten-plus encounters without you planning anything. We wrote about the research behind it in guess, struggle, remember.
The catch is the opposite of immersion’s: a system alone gives you words, not conversations. Plenty of learners know thousands of words from flashcards and still freeze when someone talks to them. We covered that side in is Anki good for learning Chinese? You need all four.
“But I only want to speak”
Fair enough. Most people who learn Mandarin want to understand people and talk back, not read novels. Good news: a review system doesn’t have to be about characters. You can review a word by hearing it and recalling what it means, or by seeing the meaning and saying it out loud. That trains exactly what a conversation asks for.
And if you do want to read and write, a system goes from useful to essential. Characters don’t come by themselves from hearing people talk. You need thousands of them, each with its own look and strokes, and nobody picks those up from dinner parties.
A simple weekly setup
- Every day, 10–20 minutes: review what’s due, then add a few new words. Same time each day if you can.
- A few times a week: listen to real conversations, and say your part out loud.
- Once a week, if you can: half an hour with a tutor or language partner, using the words you’ve been reviewing.
- Whenever life gives you some: immersion. Dinner with friends, shows, WeChat. It sticks far better once you’ve already met the words.
How Mandarin Hero fits in
Mandarin Hero covers the parts a tutor and immersion leave open, and takes you into real conversations along the way:
- Lessons for real situations, like the dinner above, a café or a taxi. Each starts with its words and phrases, then the conversation the way people really talk, then a role-play where you say your part out loud.
- Flashcards with spaced repetition built in. Every word from a lesson comes back right before you’d forget it. A word only counts as mastered once every card for it has reached a 21-day interval.
- A steady daily inflow. You tell it how many minutes a day you have, and it sets your new cards to match, ten a day for ten minutes.
- Listen and speak, or read and write, or all of it. The app asks what you’re learning for. Speak-only learners get listening and speaking cards; characters are an option, not a requirement.
To be honest about the limits: it doesn’t grade your pronunciation, and it isn’t a real person. Keep the tutor and the dinners. Mandarin Hero makes sure the words are there when you need them. Wondering whether it’s worth starting at all? Here’s what being really fluent gives you.
