Which languages each generator says it supports, and where

Why one language list is three claims wearing one label

These pages carry the distinctions the atlas is built on. Each exists because a single word on a vendor page is doing the work of three separate claims. As of 2026-09-12.

One word, three promises, and the gap between themSupport is used for menus, for generated output and for voices. The three claims have different costs to make and different consequences if wrong. A page that announces a number of supported languages is nearly always counting interfaces, and is nearly always read as counting voices.What a support claim usually coversOnly interfaceCounted in headlinesMenus, Help centre, Billing screensBoth listsClaimed for bothA short list of major languagesOnly outputNeeded by a productionDialogue the model writes, A voice tospeak itThe middle column is where the two lists overlap
Fig. 1 The number in a headline and the number a production can use are rarely the same number, and no vendor page says which one is on offer.

Support is the word in question. Applied to an interface it means menus. Applied to output it means the model will write or speak the language. Applied to voices it means a specific inventory exists. A page announcing thirty languages is usually making the first claim and being read as making the third.

A second explainer covers blanks. An empty cell in this atlas means the vendor's pages do not address the question, which is not the same as a vendor saying no. The distinction matters most in the markets where coverage is thinnest.

Neither page puts a language in the register. Both are here so that a reader can tell which of the three claims a vendor is making, and can disagree with a specific step rather than with the atlas as a whole.

1The explainers

  • Three layers — The language of the interface, of the documents a tool generates, and of the dialogue it speaks are three separate settings that move independently.
  • How hreflang works — Language alternates tell search engines which URL serves which language.
  • Subtitles and localisation — Script, audio and subtitle are separate layers with separate costs.

A register entry that depends on one of these distinctions points at this section instead of compressing the case into a parenthesis.

The rest of the atlas: Markets, Tools, Output, Questions, Data. How a list earns a column is set out on the counting page.
