Two vendors that split their lists along different cuts

Both vendors publish two spoken-language lists instead of one. VEED divides the languages it can detect in a source file from the ones it can dub into. HeyGen divides the languages a voice exists for from the ones a finished video can become. As of 2026-09-22.

Inclusion rule. The two vendors in this register that publish more than one spoken-language list. The rows show which distinction each split makes. Order. First list, second list, then the axis and the totals.

1Input against output is the sharper cut

One split tells a buyer that 43 languages can be recognised but not spoken, which reduces an apparent 72-language product to a 29-market one. That is the most commercially consequential distinction any list in this register draws.

The other split separates two products rather than two ends of one. Both are useful, but only the first changes the number a buyer should be using, which is why the register records the smaller figure as the entry on that row.

2Neither vendor totals its own lists

Four lists between them and not one count. Every figure on either row here was produced by counting entries, which anyone can repeat and nobody should have to.

It also means neither vendor can be quoted with a single number from its own documentation. One of them does publish a marketing figure above the lists, larger than either of them; the other publishes none at all, which is rare here.

3Both sites declare nothing

Neither vendor declares a language alternate on its own host, so both site cells are empty and both of the support articles holding these lists are served in English.

That combination shows up three times in this register and always at a dubbing vendor. It is the clearest evidence here that documenting output languages and translating your own pages are separate decisions taken by separate teams.

4Sources

Counted from the VEED dubbing languages article and read against the HeyGen voice languages article. Both rows are kept in the register under one rule, set out on how counted; the column is described on dialogue language.

5Both of them against the rest of the column

Inclusion rule. Tools with a public English site selling AI video generation or AI video dubbing. Site languages count hreflang alternates served from the host being read; x-default and alternates pointing at another host are not counted, for every vendor alike. Order. Alphabetical by tool name.

Other pairings that turn on the same kind of difference: Synthesia and HeyGen, Rask AI and Vidnoz. The full set of pairings is here; single cells are indexed at entries.
