Why word-by-word Japanese sounds slow
Building a sentence from individual words requires choosing each word, each particle and each ending in sequence. Every one of those choices costs time, and the costs add up to the pauses that make learner speech recognisable.
Fluent speakers avoid most of that cost by recalling ready-made pieces. Research on spoken language consistently finds that a large share of natural conversation is formulaic in this way, which explains how people speak quickly while apparently thinking about something else.
The implication for study is uncomfortable but useful: learning more individual words does not, by itself, make you faster. Learning sequences does.
What a chunk looks like
A chunk can be a whole utterance, a fragment that begins one, or a frame with a slot. What makes it a chunk is that you produce it as a single motion rather than as a series of decisions.
The most valuable ones for conversation are the openers and connectors, because they buy time at exactly the moments when you need it and because they attach to anything.
| Japanese | Romaji | Meaning |
|---|---|---|
| というか、 | To iu ka, | Or rather, |
| それはそうと、 | Sore wa sō to, | Anyway, on another note, |
| だと思うんですけど、 | Da to omou n desu kedo, | I think it is, but |
| どちらかというと、 | Dochira ka to iu to, | If anything, |
| わけじゃないんですけど、 | Wake ja nai n desu kedo, | It is not that, but |
| ちょうど今、 | Chōdo ima, | Right now, |
Each of these is one motion for a native speaker. Produced word by word they are slow and slightly wrong; produced whole they are indistinguishable from natural speech.
Chunks that carry a whole turn
Some chunks are large enough to be an entire conversational turn. These are worth collecting because they cover recurring social moments where hesitation is most costly: agreeing, declining, sympathising, and admitting you do not know.
They are also the safest place to start, since the register is fixed inside the chunk and you cannot get it wrong by assembling it badly.
| Japanese | Romaji | Meaning |
|---|---|---|
| それ、分かります。 | Sore, wakarimasu. | I know what you mean. |
| たしかに、そうですね。 | Tashika ni, sō desu ne. | That is true, yes. |
| ちょっと考えさせてください。 | Chotto kangaesasete kudasai. | Let me think about it. |
| 行きたいのは山々なんですが。 | Ikitai no wa yamayama nan desu ga. | I would love to go, but. |
| それは大変でしたね。 | Sore wa taihen deshita ne. | That must have been hard. |
| すみません、勉強不足で。 | Sumimasen, benkyō busoku de. | Sorry, I do not know enough about it. |
Harvesting chunks from real input
Chunks from a list are worth less than chunks from something you watched, read or lived through, because the situation comes attached and the situation is what triggers recall later. Harvesting is a habit rather than a study session: notice a sequence, write it down with where it happened, move on.
Keep the collection small and personal. Five a week that fit the things you actually talk about will be used; fifty from a frequency list will not.
- Write the chunk exactly as heard, including the particle it came with.
- Note the situation in one phrase: refusing an invitation, agreeing reluctantly.
- Mark whether it is casual or polite; chunks carry register with them.
- Note the slot if it has one, so you know what can vary.
- Cap it at five a week and drop anything you have not used in a month.
Storing chunks so they come back
A chunk written in a notebook and never revisited is a chunk you have not learned. It needs to return on a schedule, and it needs to be tested by production rather than recognition, which means the prompt should be the situation and the answer should be the Japanese.
Spaced review is what makes this affordable. Five new chunks a week is a small load when they come back on an expanding schedule, and it compounds into a few hundred within a year.
In Unihongo, chunks saved during a session become flashcards in your deck, and words you save from a session report join them, so the collection builds from what you actually tried to say rather than from a separate list you have to maintain by hand.
Review chunks aloud, always. Silent review of a chunk trains you to recognise it, which is not the skill you are trying to build.
Getting chunks up to speed
A chunk that takes you a second and a half to produce is not yet a chunk; it is a short sentence you are assembling. The final step is speed work: saying it repeatedly until it comes out as one uninterrupted motion, with the right rhythm and the internal pauses in the right places.
Unihongo's pronunciation lab is useful here because it scores individual lines against a native model, so you can see whether the chunk is holding together or breaking into pieces. Length and the small tsu are the usual casualties when a phrase is produced too carefully.
Then it has to survive a conversation. Using the chunk in the immersive 3D classroom, where you are speaking aloud under time pressure rather than typing into a box, is the real test, and the session report will show whether it arrived whole or in fragments.
A chunk is finished when you catch yourself using it without having decided to. That is the point at which it has stopped being study and become speech.
