Which languages each generator says it supports, and where

Which vendors name the languages rather than count them

Five vendors in this register publish a named set of spoken languages. Four publish a figure with no set behind it. Nine publish nothing in that column, and only a set lets a reader check one particular market. As of 2026-09-12.

Five sets, five different shapes, and one thing in commonOne is a single table. One is two articles split by purpose. One is two counted sections. One is two lists split by direction. One is a set matching an interface list with a single addition. No two are directly comparable.Longest set firstOne table143 named rows, mixing languages and regional varieties.Two counted sections91 languages and 117 dialects, each with its own total.Two lists by purposeVoices, and the languages a finished video can become.Two lists by direction72 the tool can hear against 29 it can speak.A set plus oneFifteen named, and a sixteenth offered for speech only.All five can be searched; none names a variant

Inclusion rule. Vendors publishing a named set in the voice column. A vendor publishing a count, however large, is excluded. Order. Alphabetical by tool.

1Five sets, five different shapes

One is a single table. One is two articles split by what the languages are for. One is two sections with their own totals. One is two lists split by direction. One is a set matching the interface list with one addition.

No two of these are directly comparable, and the register does not rank them. What they have in common is the only property that matters to a reader with a market in mind: the language names are on a page that can be searched.

2The sizes range across two orders of magnitude

From fifteen to a hundred and forty-three. The largest belongs to a translation feature, the smallest to a generation setting, and comparing them directly would compare a catalogue service with a production tool.

Which is why the register prints the mechanism beside the figure. Two cells holding a set of very different sizes can be the right answer for different buyers, and sorting the column by length would suggest otherwise.

3What even a named set leaves open

Which variant of each language. How many voices exist per language. Whether the quality holds at the end of a long list. And for a mixed table, how much of the length is one language repeated as regional variants.

Not one of the five answers any of those. So the best available disclosure in this category still stops short of the casting question, which is worth stating rather than letting a long list stand in for an answer.

Inclusion rule. The three columns this register keeps. A column stays listed even when no vendor names a list, because silence in a column is itself recorded. Order. Alphabetical by column name.
