Languages HeyGen publishes for
HeyGen (heygen.com) declares no language versions of its own site and publishes two separate named lists in its help centre, one for voice languages and one for the languages a video can be turned into. Neither list prints a total; the marketing page says 175+. As of 2026-09-22.
| Column | Count | Codes |
|---|---|---|
| Site languages | None declared | - |
| Output languages | No list published | - |
| Voice languages | Two named lists | no total printed |
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.
1Two lists, kept apart, neither carrying a number
The help centre keeps voice languages and translation languages in separate articles, and the separation is deliberate enough that each has its own title. A voice language is one a synthesised speaker can read a script in. A translation language is one an existing video can be turned into, which involves detection, a translation pass and lip movement on top of the voice. They are related capabilities with no reason to have identical coverage.
Both run alphabetically, from Afrikaani entries at the top through to Zulu, and both name regional variants as their own rows rather than folding them under a parent language. Neither article prints a total anywhere on the page. That is the opposite failure from the one this register usually records: a reader can check any specific market in a second and cannot state the size of the inventory at all.
2The marketing number and the per-job ceiling
The translator page is titled for 175+ languages and repeats the figure a dozen times down the page. Whether that counts languages, dialects or both is not resolved on the page, which offers 175+ languages and 175+ languages and dialects in different sentences. The register records the quoted claim and leaves the arithmetic where the vendor left it.
The same page carries a limit that is more useful than the headline: a single video can be translated into up to ten languages at once. That is an operational fact a production can plan against, and it is the kind of sentence that almost never appears on a vendor page. A series being released into thirty markets is thirty jobs in batches of ten, not one job, and knowing that before signing is worth more than knowing whether the ceiling is 175 or 200.
3Nothing declared for the site, nothing published for documents
The site declares no alternates. For a product whose entire pitch is crossing languages that reads as an omission, and it is recorded as one: the declaration is missing, which is not a finding that translated pages do not exist somewhere behind a switcher. The register counts what is in the markup, identically for every vendor.
The middle column is empty too. Nothing on these pages says what language a generated script or caption file arrives in when the interface is being driven by a non-English speaker, and that is the column almost nobody in this register fills. A vendor with two named language lists and a published per-job limit is clearly willing to document itself; this is one thing it has not documented.
