Languages Higgsfield publishes for

Higgsfield (higgsfield.ai) declares five same-host language versions of its site: German, English, Spanish, Japanese and Korean. One of the five was opened and is served as a page in that language rather than an English page with a switcher. Nothing is published about output or voices. As of 2026-09-22.

Inclusion rule. The same three columns are kept for every tool in the register; a column the vendor does not publish is recorded as no list rather than filled from a product description. Order. Fixed column order, identical on every tool page.

1Five alternates, and one of them opened

A declaration is cheap, so the same check applied elsewhere in the register was applied here: open one alternate and see what is behind it. The Japanese page comes back with its navigation, its product names and its section headings in Japanese, and the document itself declares Japanese as its language. That is one check on one language, recorded as exactly that, and it says nothing about the other four.

It is worth doing because the alternative failure is common and invisible from the markup. A vendor can declare ten alternates that all resolve to the same English page, and the count would look identical in a table. One opened page does not prove a programme, but it distinguishes a declaration that leads somewhere from one that does not, which is more than a count on its own can do.

2German, Spanish, Japanese, Korean: a set that says where the buyers are

Five is a small declared set and the choice inside it is informative. There is no French, no Portuguese and no Chinese; there are two East Asian languages out of four non-English entries. For a vendor selling generation tools to advertising and marketing teams, Japan and Korea are substantial markets with their own agency structures, and a translated site is the cheapest way to be legible in them.

None of that is a claim about the product, and the register will not let it become one. The site column and the voice column are filled by different vendors here almost without overlap, and this row is on the site side of that split. A Korean agency can read these pages in Korean and cannot find out from them what language a generated shot will speak.

3Two columns with nothing in them

Both output columns are empty, and for a tool of this kind that is the ordinary state rather than an outlier: seventeen of the entries here publish nothing about the language of generated documents, and nine publish nothing about voices. An empty cell records that the vendor's pages do not address the question. It is not a finding that the capability is absent.

What would change the cell is narrow and specific. A named list of spoken languages, or a published rule about what language a generated description comes out in, on a page anyone can open. A demo in Japanese would not, and neither would a support reply, because neither is something a second reader could repeat.

5Where this entry sits in the register

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.

Next entry in the register: Kling AI. Previous entry: HeyGen. Every tool side by side is in the register, and the rule behind each count is on the how counted page.
