When a Translation App Is Enough, and When You Need a Person

You have nodded at something you did not understand and hoped it was not important.

Most people have. The translation app on your phone got you the gist, you filled in the rest from context and tone, and you left not quite certain what had been agreed. Usually that is fine. Occasionally it is a lease you have just signed.

Machine translation has become genuinely good. It is also not the same thing as interpreting, and the difference is not about accuracy percentages. It is about what happens when a conversation stops being simple.

What machine interpretation is good at

It is fast, it is available at two in the morning, and it costs almost nothing. For a large share of everyday situations that combination is unbeatable.

Asking for directions. Ordering. Confirming a delivery slot. Reading a sign. Checking which platform. Explaining that you will be ten minutes late. These have a narrow range of likely meanings, low stakes if the first attempt fails, and an obvious retry if it does. You can tell immediately whether it worked, because the other person either points you down the street or looks confused.

For conversations shaped like that, reaching for a person is overkill.

What a person adds

A human interpreter is not simply a more accurate version of the same thing. They do several things a machine does not attempt.

They notice when you have not been understood. A machine renders what was said and stops. A person watches the other face, sees the moment it goes blank, and says so. Most failed conversations do not fail because a word was wrong. They fail because both sides believed they had agreed and had not.

They can ask. When something is ambiguous, an interpreter can stop and clarify before carrying it across. A machine commits to one reading of an ambiguous sentence and moves on, and you never learn there was a choice.

They handle the parts that are not words. Overlapping speech, someone trailing off, a term with no clean equivalent, a question that is really a polite refusal. These are routine in real conversations and they are exactly where a literal rendering goes wrong.

They are accountable. A person can tell you afterwards what was actually agreed. That matters when the conversation has consequences you will live with.

The rule, as plainly as we can put it

Use a machine when the conversation is short, the stakes are low, and you would know straight away if it went wrong.

Use a person when being misunderstood would cost you something you cannot easily undo.

That second category is smaller than people fear and larger than they expect. It is the lease and the deposit. The call to the bank about a charge you did not make. The utility company explaining why the bill tripled. The conversation with a relative about something that matters. A medical appointment where you need to describe a symptom precisely and understand the answer.

Most people get this wrong in one direction or the other. Either they use a machine for everything and absorb the occasional expensive misunderstanding, or they avoid the conversation entirely and let the problem grow, which is the more common and more costly mistake.

Why people have usually had to choose badly

Until recently the choice was not really available. Professional interpreting is sold to organisations. A hospital books it, a court books it, a company books it under contract with an account manager and a minimum spend. An individual trying to sort out a tenancy has had a phrasebook and a translation app, and that is all.

That is why so many people end up nodding. Not because they do not know the difference between a machine and a person, but because only one of the two was ever on offer to them.

What it costs to have both

VoCo is our answer to that. One app, both options, and you decide which every time you make a call.

AI interpretation runs at $0.25 a minute, so five dollars of credit is twenty minutes of it. A live professional interpreter is $1.25 a minute for Spanish and $1.75 for other languages, so the same five dollars is four minutes with a person. You add credit when you want it. There is no contract and no subscription, and you are billed only while you are actually connected. If no interpreter joins within three minutes, the call ends and you pay nothing.

AI interpretation covers more than 70 languages and professional interpreters can be requested in more than 80, with availability varying by language. It is on Android, free to download.

We are a language services company that has been providing interpreting and translation for more than twenty years, mostly to organisations. VoCo exists because the people who need an interpreter occasionally, and will never sign a contract to get one, have been left out of that entirely.

One practical thing

Whichever you use, say less at a time than feels natural. Short, complete sentences interpret cleanly in both directions. Long ones with several clauses are where meaning gets lost, by machine or by person.

And if you are using VoCo, allow microphone access when it asks. It is what lets it hear the call.
