Speech and voice controls, as each vendor documents them

Which language the performance is in

Synthesia publishes a voice catalogue carrying a formal language name, a native name and a code. SceneMixer names 15 dialogue languages and adds Cantonese for speech. Six others publish a number, a loose plural or a bare language field. Nine of the 17 models publish neither. As of 2026-09-12.

Two ways of stating which languages a performance can be inOne vendor names fifteen dialogue languages, adds one more for spoken output only, fixes the choice at project level and states that the model delivers the line in that tongue while the shot renders. Another states native audio covering five languages and identifies none of them.A named listA count onlyWhat is publishedThe languages, by nameHow many there areWhat a buyer can checkWhether their language is on itNothing about their languageWhere the choice is madeFixed at project levelNot addressedFixing the tongue at project level removes a per-shot failure mode

Inclusion rule. Statements about spoken output language on the vendor's own pages. A count is recorded as a count and is never expanded into a list. Order. Entries publishing a list first, then counts, then silence.

1Fixing the tongue at project level removes a per-shot failure mode

Anchored to the project, the choice propagates downward and no single generation can drift away from it. Anchored to the request, somebody has to supply it correctly on every shot of every episode, and the failure shows up as one segment in the wrong tongue deep inside a delivered cut.

Exactly one entry here says where its anchor sits. Elsewhere the question never comes up, since no page mentions spoken output.

2A tally and an enumeration answer differently sized questions

Somebody casting for Brazil needs one word: Portuguese, yes or no. An enumeration settles that in a second. A tally leaves it open no matter how large the number, which is why this column is ordered by whether names appear rather than by how many.

Enumerations also cost more to walk back. Drop an entry and a reader can point at what vanished; shrink a tally and there is nothing to point at.

3The method claim that follows from generating in-language

If the line is performed in the target language as the shot renders, there is no translated track laid over finished footage and therefore no dubbing pass. That is a claim about where the language decision sits in the pipeline, and it is checkable in principle.

How the delivery lands on an ear from that market is a different sort of judgement, one no record of published sentences can reach. Marketing copy blurs the two routinely; the fields here refuse to.
