How to Localize Your Game's Dialogue With AI Voices

Localization is one of the first things an indie game team cuts. Translating your script is affordable enough, but voicing every line again in each language means another round of casting, booking, and studio time, multiplied by however many languages you want to ship. So most small teams release subtitled-only, promise "voices coming later," and never get back to it.

AI voices change the economics of that decision. You can generate localized dialogue from your translated script in minutes, drop it into a test build, and actually hear whether your pacing, UI timing, and dialogue flow survive the translation before anyone commits to a full-cast recording. This guide walks through how to do that with AudioProducer.ai, and where the honest limits are.

What AI voice localization is good for (and what it isn't)

Be clear-eyed about this, because it saves you from disappointment later.

Where it shines:

• Testing a localized build before you fund one. Translated lines are often longer or shorter than the English original. Hearing them read aloud in context is the fastest way to catch a subtitle that now runs twice as long, a cutscene beat that no longer lands, or a menu bark that overflows its timer.
• Shipping voice where you otherwise would have shipped silence. For a free-to-play prototype, a game-jam entry, or an early-access build, AI-localized dialogue is a real improvement over text-only in a language your players actually read.
• Prototyping the casting. You can try a handful of voices per character, per language, and settle on a direction before you ever brief a human actor.

Where it isn't a drop-in replacement: a flagship narrative game where voice performance is part of the art still wants human actors for the final ship, especially for emotionally heavy scenes. Treat AI localization the way you'd treat scratch voice lines for a prototype: fast, iterable, good enough to make decisions with, and genuinely ship-ready for plenty of games, but a creative choice rather than an automatic one.

A workflow for localizing game dialogue

The core idea is the same one behind voicing NPCs in your indie game: your dialogue is already text, so turning it into audio is a generation step, not a recording session. Localization just adds the translation pass in the middle.

1. Export your dialogue as text. Pull your strings out of your localization table or engine (a column per language is ideal). Each line becomes a paste-ready block of dialogue.
2. Translate per language. Use your existing translation pipeline, a professional translator, or a machine-translation first pass that a native speaker reviews. AudioProducer voices your script; it doesn't translate it, so the quality of the translation is on you.
3. Create a project per language. Paste the translated dialogue in, and assign a voice to each character. Because there's no limit on the number of projects, a separate project per language keeps your voice casting organized.
4. Assign voices and generate. Tweak each character's voice in the Characters panel, then generate the audio. You get per-line files you can name and drop straight into your engine's audio buses.
5. Drop it into a test build and listen in context. This is the step that pays for the whole exercise: you hear the localized lines against the actual UI and pacing, not in a spreadsheet.

If your game leans on longer scripted scenes, the same approach extends to voicing cutscenes and to dialogue-heavy visual novels, where the volume of text makes re-recording every language by hand especially painful.

Checking voice coverage for your target language

This is where honesty matters most. AudioProducer runs a multilingual voice model, and a broad set of voices are tagged for non-English narration, so many target languages are supported. But the quality and the number of available voices vary by language, and the marketing site itself is English-first.

So before you plan a full localization around a specific language, do the practical thing: open the in-app voice library, filter for your target language, and listen to the voices actually available for it. What you hear in the library is what you'll ship. For a widely spoken language you'll usually have options; for a less common one, check first rather than assume. If you can't find enough coverage for a character, that's your signal to keep that language subtitled-only for now.

Keeping your localization budget sane

You can start on the free tier, which gives you 1,200 words a month at no cost and with no credit card, which is enough to localize a slice of dialogue in one language and prove the workflow out. From there, your word allowance resets every billing cycle and there's no cap on projects, so you can localize a large script across several languages by working through it a cycle at a time, at no extra cost, or finish it all at once. The point is that localized voice stops being an all-or-nothing budget line and becomes something you can do incrementally, language by language, as the game earns it.

Create a free account, paste in a few translated lines, and hear your game speak a second language before lunch.
