Subtitles, studio dubbing or AI voice translation: how to choose
What each option delivers, what it costs you, and which one breaks first when the content changes.
Draft. The cost and turnaround sections need real numbers from our own work before this publishes. Written up to that point.
The three options, honestly
Every multilingual training team makes this choice about three times a year and almost never writes down why. The result is a different answer each time, usually driven by whoever had budget.
Subtitles are cheap and fast, and they work if your audience will read. A lot of workplace training gets watched on a phone in a break, and a subtitled safety module competes with everything else on that screen.
Studio dubbing sounds right. It also arrives in weeks, costs enough that you quietly drop the fifth language, and turns every future content change into a new booking.
AI voice translation sits between them, and it is the option changing fastest, which means last year’s opinion of it is probably out of date.
What actually decides it
Not quality in the abstract. Three practical things:
- Does anyone have to understand this, or just receive it? Compliance training has a comprehension purpose. Subtitles put that at the mercy of whether people read.
- How often does the content change? If it is stable for years, dubbing amortises. If a procedure changes twice a year across nine languages, dubbing is a subscription to a problem.
- Do the slides carry meaning? In training they usually do, and that is where subtitle-only and audio-only approaches both quietly fail.
Where each one breaks
Subtitles break when the viewer will not read. Dubbing breaks when the content changes. AI voice translation breaks when nobody checks the output, which is a process failure rather than a technology one and is therefore the easiest of the three to fix.
What we do ourselves
We produce training for a living, so we make this choice with our own money. Stable, high-stakes content that will not change: worth dubbing properly. Anything that changes, anything with a deck, anything going into a fourth language: our own workflow, with a person reviewing before it ships.
