An English-only help centre behind a claim of 175+ languages
HeyGen declares no language alternates on its own host. Its help centre, which is where the spoken-language lists live, is served in English, and the marketing page above those lists promises translation into more than 175 languages. As of 2026-09-22.
| Page | What it states | Language the page itself is served in |
|---|---|---|
| Home page | No alternates declared | English |
| Video translator page | More than 175 languages | English |
| Help centre, voice languages | A named list, no total | English |
| Help centre, translation languages | A second named list, no total | English |
Inclusion rule. Every page this register reads for this vendor, with the language the page is served in recorded beside what it claims. Order. Marketing pages first, then the help centre articles.
1The claim and the documentation are in the same language
A promise of more than 175 languages is made on a page available in one. That is not a contradiction, but it is the shape of the disclosure: the languages are a property of the output, and the company has not treated its own pages as part of the offer.
For a buyer who does not read English, the practical consequence is that the list they need in order to check their market is only readable in a language they may not have. The register notes it because it is the kind of thing a language total hides.
2Nothing declared is a different finding from nothing offered
This column counts hreflang alternates on the host being read, the same way for everybody. No alternate was found, so the cell is empty; a translated page reachable some other way would not change the entry unless it were declared.
The rule is narrow on purpose. It can be re-run by anyone with a browser and it gives the same answer twice, which is worth more here than a broader rule that only this register could apply.
3The vendor that publishes most has translated least
Two named lists plus a per-job cap makes this one of the most fully documented spoken-language offers in the register. It sits beside the emptiest possible site cell, which is the inverse of what a reader scanning language switchers would predict.
Read together, the two cells say that disclosure and localisation are separate budgets. One is spent on telling buyers what the product does; the other is spent on speaking to them in their own language while doing it.
