Why dialogue in a translated book sounds slightly stiff

When a translated book feels slightly off, the culprit is usually not the descriptions but the speech. A clumsy description gets forgiven. A character who sounds like they are reading from a document does not.

Why it happens

Real speech is deliberately incomplete. People break off sentences, skip words, say half a thing and trust the listener to fill in the rest. Translation does the opposite: it completes. It closes the broken sentence, adds the word that went without saying, explains the hint that was too subtle.

Each of those completions looks correct when you examine it alone. The trouble is that they accumulate. By the end of the process, characters speak in full, polite, faintly over-long sentences — which is exactly what a reader registers as "unnatural", even when they cannot say why.

The sign that is easy to spot

There is a simple test: if every character in the book speaks in the same style, something has been lost. The original almost always has differences — one speaks curtly, one rambles, one is more formal. When those differences blur, the book sounds as if a single narrator wrote all of it.

What to ask for in advance

This is where one sentence before the work starts is worth more than any correction afterwards.

Ask explicitly for dialogue to stay as short as it is in the original, even where meaning becomes slightly less explicit. Ask for the differences between characters to survive — who is terse and who goes on. And if the book has a character who speaks unlike the others, in slang or a regional way, say in advance how you want that handled.

For that character there are three legitimate routes: drop the accent marking and set them apart by their word choices and rhythm; find an equivalent way of speaking in the new language; or mark lightly, with one recurring word or a habitual sentence shape. The choice matters less than consistency — the worst outcome is one approach in chapter two and another in chapter ten.

The one-minute check

Take a page with plenty of dialogue and ask someone who speaks the language to read it aloud. You do not need to understand a word. You are listening to the flow: do they read straight through, or stop, back up, correct themselves.

Text written the way people talk reads easily aloud. Text that has been over-explained trips in the middle of every line. It takes a minute, and it tells you more than quietly reading ten pages.

What about books with no dialogue

In non-fiction or a professional book the same problem appears in another form: the text becomes more formal than the original. An author who writes in a light, conversational voice can end up with something that reads like an academic paper. Here too, one sentence up front — "keep the tone conversational, not academic" — makes the difference.
