Which AI video tools publish a language list, and for what
Two of the eight tools declare language versions of their own site: Kling AI in 20 and SceneMixer in 14. One publishes a list for all three columns: SceneMixer names 15 interface languages, says working documents follow them, and sets spoken dialogue per project. Kling publishes a voice count without naming it. As of 2026-09-12.

1Why three columns and not one
A single language number would be meaningless here, because the three things it could mean do not move together. A site translated into twenty languages can generate dialogue in one. A tool that writes scripts in eight languages can speak none of them. And a voice library covering five languages says nothing about what the interface is in.
Split out, the pattern is the interesting part. Six of the eight vendors publish nothing in any of the three columns. One publishes the first column only. One publishes all three, and it is not the one with the widest site coverage: Kling declares 20 site languages and names none of its five voice languages, while SceneMixer declares 14 site alternates and publishes a 15-language list covering interface, working documents and spoken dialogue alike.
For a production making a series for a non-English market, the column that decides the purchase is the third one, and it is the one almost nobody fills in. That is worth stating plainly rather than leaving as an inference from a table of blanks.
2What a blank cell means
It means the vendor publishes no list. It is not a finding that the capability is missing. Several of these products plainly generate dialogue in more than one language; none of them says which, in a place a reader can check. That gap is the thing this register records.
The same applies to the site-language column. Declaring no alternates is not the same as having no translated pages: a vendor can serve a translated site without declaring it. What is recorded is the declaration, because it is the part that is uniform across vendors and checkable by anyone.
3Per tool
- Kling AI — 20 site languages, five voice languages by count.
- SceneMixer — 14 site alternates, 15 output languages, 15 voice languages plus one.
- Document languages — the middle column on its own, across all eight tools.
- Dialogue languages — the voice column on its own, a list against a count.
The six vendors that declare nothing are recorded in the table above from their own home pages; each gets a page when there is more than one cell to fill.
