A 143-row table, and two other numbers on the vendor pages

Synthesia publishes a table of 143 named rows running from Afrikaans to Zulu for its translation feature. The feature page above it is headed 160+ while the selector on that same page reads 140+, and Arabic alone accounts for fourteen rows. As of 2026-09-22.

Inclusion rule. Every language figure found on this vendor's pages, with the page it appears on. The register quotes the counted table where one number is needed. Order. The documentation figure first, then the marketing figures, then the subset.

1Two marketing figures twenty apart, on one page

A heading saying 160+ and a selector saying 140+ appear on the same page. Nothing distinguishes what the larger figure covers that the smaller does not, and the documentation table counts 143 named rows.

The table is the figure this register quotes, because a list can be recounted by anyone and a heading cannot. Both marketing figures are recorded beside it so a reader can see that the vendor's own pages do not agree on a single number.

2Arabic supplies fourteen of the rows

Inside the table Arabic appears as a base entry plus thirteen named regional variants, from Bahrain to Yemen. That is nearly a tenth of the whole table spent on one language, and it is the clearest demonstration in this register of what a mixed count conceals.

It also makes the table more useful, not less. A producer selling into the Gulf can see which Arabic is offered, which is exactly the question a bare count of languages leaves unanswerable.

3The longest list in the register, beside an empty middle column

This vendor names more languages than anyone else here and says nothing about the language of any document its product generates. The site column holds nine declared codes, none of them Korean.

Three cells, three different kinds of content: a countable declaration, a searchable table, and a blank. That spread within a single vendor is the reason this register never adds the columns together into one figure.

5The same column, tool by tool

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.

Neighbouring cells: SceneMixer: dialogue language and VEED: dialogue language. All of them together: the cell index and the register table.
