Five codes and two, with one set inside the other
Higgsfield declares five same-host alternates and D-ID declares two. Both of the shorter set's codes appear in the longer one, and one of the five was opened to check that a declaration corresponds to a translated page. As of 2026-09-22.
| Property | Higgsfield | D-ID |
|---|---|---|
| Codes declared | de, en, es, ja, ko | de, en |
| Contains the other set | Yes, both codes | No |
| A page opened and read | Yes, the Japanese one | Not checked |
| Voice languages | No list published | More than 120 claimed, none named |
Inclusion rule. The two shortest declared sets in this register, with the spot check recorded against the single code it was performed on. Order. Larger declared set first.
1Containment at the bottom of the column
Two codes inside five, five inside nine, nine inside thirteen: four declared sets in this register nest exactly, and these two are the first two links. Nothing is dropped at any step.
That suggests the order in which this category translates its pages is fairly settled. German and English come first, then Spanish, Japanese and Korean, then French, Portuguese, Russian and Chinese, then Southeast Asia.
2One declaration was opened, the other was not
Counting alternates measures markup. A tag can point at a stale page, a redirect or an English page with a switcher on it, and the count looks identical in every case. So one code in the longer set was opened.
The Japanese page is written in Japanese, navigation and headings included, and the document declares itself as Japanese. That is one check on one language at one vendor, and it is recorded as exactly that rather than generalised across the pair.
3The next column separates them completely
One vendor publishes nothing about spoken languages. The other claims more than 120 languages and accents without naming any. So the vendor with fewer site codes is the one with something, uncheckable, in the voice column.
Between them the pair make a small point precisely: at this end of the site column the numbers are too close to separate vendors, and what distinguishes the rows is what each of them did next.

Counted from the markup of higgsfield.ai and d-id.com, with the Japanese page opened. Both rows are kept in the register under one rule, set out on how counted; the column is described on site language.

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: Runway and Vidu, Fliki and HeyGen. The full set of pairings is here; single cells are indexed at entries.
