Speaking Through an Interpreter So Nothing Gets Lost

Why this matters

Getting a professional interpreter on the line solves half the problem. The other half is you. Most of what goes missing on an interpreted call is lost before the interpreter opens their mouth: a forty-second answer full of trade slang that no interpreter can render whole, a joke that lands as an insult, "you've got a few years left on it" heard as a guarantee. The interpreter can only carry what you hand them, and what you hand them has to be shaped for the trip. These techniques come from medical and legal interpreting, where a lost sentence costs more than a callback, and they work the same way in a customer's kitchen.

This article covers the technique for working with a trained interpreter, on the phone, on video or in person. Setting up the line is covered in the sibling article; see related: Using a Phone Interpreter Service.

1. Talk to the customer, in the first person

Look at the customer, not at the phone or the interpreter, and speak to them directly: "I recommend replacing the valve," not "Tell her I recommend replacing the valve." A professional interpreter will answer in the first person too, so you will hear "I don't understand why it costs more" in the customer's voice rather than "She says she doesn't understand."

Why it matters: third-person speech ("ask him if...") invites the interpreter to paraphrase and summarize, because you have made them a go-between rather than a voice. It also cuts the customer out of their own conversation; they watch two people talk about them.

2. Speak in chunks of one idea, then stop

Say one idea in one or two sentences, roughly fifteen to twenty words, then stop and wait. Do not stack the diagnosis, the price and the schedule into one answer.

Why it matters: consecutive interpreters hold what you say in short-term memory, sometimes with notes. Past about two sentences, even good ones start compressing, and compression is where qualifiers disappear. "It probably needs a new valve, but I want to test the pressure first" can come out the other side as "it needs a new valve." The qualifier was the important part.

The cue you have gone too long: the interpreter starts before you have finished, or asks you to repeat the middle.

3. Wait through the silence

When the interpreter is speaking, stop. Do not add "so basically" or start the next sentence. When the customer answers, wait for the whole interpretation, even if you think you know where it is going from their tone.

Why it matters: an interpreted conversation has twice as many pauses as a normal one, and the urge to fill them is strong. Talking over the interpreter forces them to choose which of two speakers to follow, and the customer usually loses.

4. Strip out idioms, slang and jokes

Trade talk is full of figures of speech that translate literally into nonsense: "the compressor is shot", "it's on borrowed time", "ballpark", "we'll knock it out in a day", "that's a band-aid". Sarcasm and humor are worse, because they depend on shared assumptions the customer may not have. Replace each with the literal fact: "the compressor no longer works", "this tank will probably fail within a year", "the price will be between these two numbers", "we will finish in one day", "this is a temporary repair".

Why it matters: an interpreter faced with an idiom has to stop and ask, guess, or render it word for word. All three cost you, and the last one can change the meaning entirely.

5. Say numbers the way you would write them

State every number with its unit, then repeat it: "The new tank holds fifty gallons. Fifty: five, zero." Give times with the day and date: "Thursday, the fourteenth, at nine in the morning." Never use "a couple", "a few" or "a while"; those words have no fixed size in English and none after interpretation either. Prices are said as one total, including the permit and tax, not as parts the customer has to add.

Why it matters: numbers are where interpretation errors are least visible and most expensive. Fifteen and fifty sound alike in English; in many languages large numbers are grouped differently, so a price said as "twelve fifty" can be heard several ways, which is why a price is said as a full total and then also sent in digits.

6. Let the interpreter speak for themselves when they need to

A professional interpreter will occasionally step out of the conversation to say something in their own voice, usually announced as "this is the interpreter speaking". They do it to ask what a term means, to flag that a word has no direct equivalent, or to say the customer seems to be answering a different question. When they do, answer them, briefly, and let them carry on.

Why it matters: the interpreter's question is a free warning that something was about to be lost. A tech who brushes it off ("just tell her what I said") has thrown away the one check built into the process.

7. Assume everything said in the room is interpreted

If you turn to your helper and say "this lady is going to be a pain about the price," a professional interpreter will interpret it, because their job is to render everything said in the conversation, not to decide what was meant to be private. Have side conversations away from the customer and off the call, or not at all.

8. Confirm understanding by asking for it back

At the end of each topic, ask the customer to tell you, in their own words, what happens next. "Can you tell me what we're going to do and when?" or "If you see water on the floor again tonight, what will you do?" Do not ask "Do you understand?" or "Is that okay?" Nearly everyone answers yes to those, out of politeness or to end an awkward exchange. This method is called teach-back, and it is the only confirmation that tells you anything. Why yes means little across a language gap is its own subject; see related: The Crew Said Yes but Did Not Understand.

What a chunked exchange sounds like

The same point about a leaking relief valve, delivered twice. The first try is how most techs talk. The second is the fix.

TECH: Yeah, your T and P valve's weeping, which
      usually means the tank's on borrowed time,
      so ballpark you're looking at a new one.
INTERPRETER: This is the interpreter speaking.
      May I ask what "borrowed time" means here?
TECH: Sorry. Let me start again.
TECH: There is a safety valve on the side of the
      tank. It is leaking a little water.
INTERPRETER: (interprets)
TECH: That valve opens when the pressure or the
      temperature inside is too high.
INTERPRETER: (interprets)
CUSTOMER (via interpreter): Is it dangerous?
TECH: Not today. I will test it now. If the test
      shows high pressure, I will explain the
      next step.

Notice what the second version gives up: speed. It took four turns to say what the first try crammed into one. It also gave up the conclusion the tech had not earned yet; "on borrowed time" was a guess, and the chunked version says only what the tech actually knows.

Worked example: an air conditioner estimate, nine points

A heating and cooling tech is quoting a system replacement for a couple who speak Mandarin, with a phone interpreter on speaker. Before dialing, the tech lists the nine points the estimate has to land: the current system's failure, why repair is not recommended, the two equipment options, the total price for each, what the price includes, the install date, the parts warranty, the labor warranty, and the permit inspection visit.

The delivery. The tech speaks in chunks of one or two sentences. Spoken straight through, the tech's part of the explanation runs about 9 minutes; through consecutive interpreting the call takes about 18 minutes, roughly double, which is normal. The interpreter steps in once, to ask whether "SEER" should be explained or left as a term. The tech explains it as "a rating for how much electricity the system uses to cool; a higher number uses less."

The check. At the end, the tech asks the couple to say back what they have chosen and what the warranties cover. They return 8 of the 9 points correctly. The miss is the labor warranty: they understood that the 10-year parts warranty also covered the cost of a technician's time for that whole period. The shop's labor warranty is 1 year.

The repair. The tech restates that point alone, slowly, in two chunks: "If a part fails in the first 10 years, the part is free. After the first year, you pay for the technician's time to install it." The couple say it back correctly. The tech sends the estimate in writing with both warranty periods printed as separate lines with digits.

What would have happened without teach-back. In year three a part fails. The shop sends a bill for labor. The couple believe they were promised free repairs for ten years, and from their side of the call, they were. The shop is now arguing about a conversation, and the only record is the tech's memory against two customers'. Teach-back cost about a minute and caught it.

When the technique runs out

All of the above assumes a trained, neutral interpreter. It does not fix an untrained one. When the person interpreting is the customer's child, a neighbor, or your own employee, chunking and plain words still help, but you lose the neutrality: a family member may soften bad news, skip a price that embarrasses them, or answer for the customer. That is a different problem with its own approach; see related: Serving Customers in a Language Nobody on Staff Speaks.

Three signals tell you something is being lost even with a professional: the interpretation is much shorter than what you said, the customer's answer does not fit your question, or the customer keeps looking at the interpreter rather than at you. When you see one, go back to shorter chunks and ask for teach-back on that point alone.
