> **Quick answer —** Game voice localization is expensive because re-recording is expensive. Lock the script, the character bible and the terminology before the first session, and keep a voice map so a franchise sounds consistent across sequels.[Vitra.ai Universe](https://www.vitra.ai/platform) keeps character voice and terminology intact across every language.

## Everything expensive happens after the booth

A wrong line in a spreadsheet costs a correction. The same line already recorded costs a session — studio, director, actor availability — and actor availability is what turns a small fix into a six-week wait. So the discipline is entirely upstream. Nothing goes to record until the script is final, the terminology is pinned and the character bible is agreed.

## Lock these before the first session

Locked

Why

Script, final

Re-records are the cost

Terminology

An item renamed later invalidates every line naming it

Character bible

Register and tone, per character

Pronunciation guide

Names, places, invented words

Timing budgets

Per line, where audio slots are fixed

Voice map

Which actor or voice per character, per language

The pronunciation guide is the one most often missing. Invented names have no correct pronunciation until someone decides, and if that decision happens in the booth it will be decided differently in each language.

## Consistency across a franchise

A returning character voiced by a different actor in the sequel is noticed immediately by the players who care most.

Keep a voice map per language and treat it as an asset, not a production note.

Where a human actor is unavailable, [voice cloning](https://www.vitra.ai/general/voice-cloning-for-video) can hold continuity — with consent agreed in writing and scoped to the use, which is a decision to make before the first recording rather than after.

## Where synthesis fits

Not everywhere. Narrative performance is still where human actors earn their place, and a synthetic lead in a story-driven game is noticeable.

It fits well for high-volume, low-performance content: barks, system lines, tutorial narration, live-ops updates that ship weekly and could never justify a session. [Video dubbing](https://www.vitra.ai/features/video-dubbing) handles the pipeline, and the same voice can hold across a library.

## Direction still matters

A line delivered accurately and flatly is a worse line. Emotion, pace and emphasis need direction in every language, not only the source — and a localization that budgets translation but not direction produces a technically correct cast nobody believes.

Run [quality control](https://www.vitra.ai/features/quality-control) on the delivered audio, and keep terminology in [memory](https://www.vitra.ai/features/translation-memory) so the words in the booth match the words in the [UI](https://www.vitra.ai/gaming/game-ui-string-translation).

## FAQ

**What has to be locked before a voice session?** The final script, pinned terminology, the character bible, a pronunciation guide for invented names, timing budgets, and a voice map of which actor plays which character per language.

**Why is a pronunciation guide important?** Because invented names have no correct pronunciation until someone decides. If that decision happens in the booth it gets made differently in each language and cannot be reconciled later.

**Where does synthetic voice fit in games?** High-volume, low-performance content: barks, system lines, tutorial narration and live-ops updates that ship too often to justify sessions. Narrative performance is still where actors earn their place.

**How do you keep a franchise cast consistent?** Keep a voice map per language and treat it as an asset. Where an actor is unavailable, cloning can hold continuity, with consent agreed in writing and scoped before the first recording.
