Which languages each generator says it supports, and where

Twenty-seven locales against two, in the same column

CapCut declares 27 same-host site alternates and D-ID declares two. They are the widest and narrowest entries in this column, and neither figure predicts what the other two columns hold for those vendors. As of 2026-09-22.

Two vendors that spent their disclosure in opposite placesOne vendor has translated its own site into 27 locales and says nothing about the voices in its output. The other offers two site languages and claims more than 120 spoken languages without naming any of them. Neither row answers the other's question.CapCutD-IDSite languages27 same-host alternatesTwo, German and EnglishVoice languagesNo list publishedMore than 120 claimed, none namedCheckable todayEvery code, from the markupOnly the two site codesOpen questionWhat the voices coverWhich 120 languagesOpposite ends of one column, opposite silences in the next

Inclusion rule. Two vendors chosen because they hold the extremes of one column. Rows are the register columns plus the code form, which is what the extremes differ in. Order. Fixed row order, widest declared list in the left-hand column.

1The gap is thirteenfold and means less than it looks

Twenty-seven against two is the largest ratio anywhere in this register, and it is a ratio between marketing budgets. Translating a product site is string work, and it scales with how many markets a company already sells into.

Read the other rows and the ordering reverses. One vendor publishes a spoken-language claim and the other publishes none, so on the question a production actually asks, the vendor with two site languages is the one that has said anything at all.

2Two vendors, two different silences

One says nothing about voices while publishing a count of the languages its subtitles can be produced in. The other says nothing about the documents it generates while claiming more than 120 spoken languages without naming one of them.

Both silences are recorded as silences. The difference worth noting is that one sits next to a number and the other next to nothing, and a number with no list behind it cannot be checked against any particular market.

3What would settle the comparison

A named list from either side. If the 120 were published, two site alternates would stop being the interesting part of that row; if the voices behind the subtitle count were published, 27 locales would look like the smaller claim.

Until one of them does, the only honest summary is that these two vendors have spent their disclosure in opposite places, and that a reader comparing them on a single language number would pick whichever one their question was not about.

Counted from the markup of capcut.com and d-id.com, with the spoken claim quoted from the D-ID avatars page. Both rows are kept in the register under one rule, set out on how counted; the column is described on site language.
