Speech and voice controls, as each vendor documents them

The speech table, and what each column asks of a vendor

One table holds the four fields these notes keep for every model. The table is the fastest way in; the model notes behind it carry the wording each cell was read from. As of 2026-09-12.

The four questions the table puts to every model, in orderCan it speak, can it speak as a chosen character, can it speak this language, and can the line be made to fit the shot. A production has to answer all four before dialogue is written, and each is a separate field because a model can pass one and fail the next.Sound at allAudio producedwith thepicture, orsilent footagewaiting for adub.If yesA chosen voiceWhether areferencesample cansteer who thespeech soundslike.If yesThis languageWhich languagesthe vendornames forspokendialogue, notfor menus.If yesThis durationWhether a linecan be made toland inside theshot it belongsto.
Fig. 1 Most entries stop at the first question, which is what makes the later columns worth printing empty.

Four fields, chosen because they are the four a production has to settle before writing dialogue. Whether audio is generated with the picture or attached afterwards. Whether a reference voice can be supplied. Which languages the vendor names for speech. What, if anything, is documented about line timing.

The fields were not chosen to flatter any model. Three of the four are empty for most entries, and the emptiness is the most useful thing the table shows: speech is the least documented part of generative video.

Reading the table from left to right answers a practical question in order — can this model speak, can it speak as a particular character, can it speak this language, and can the lines be made to land where the edit needs them.

1The table

  • Speech — Seventeen models on four speech fields: where audio comes from, which languages are named, how a voice attaches to a character, and what drives lip-sync.

A column is added when enough vendors document something to compare; one nobody addresses stays a question in the notes.

Other notes: Models, Fields, Routes, Side by side, Questions, Terms, Learn, Data. What counts as a documented control is set out on the reading page.
