Speech and voice controls, as each vendor documents them

Kling AI: a voice that arrives with the element

The voice belongs to the element, and the element carries it between generations. What the guide never says is where the voice came from, so there is no documented way to choose it, audition it or replace it. As of 2026-09-12.

Persistence solved, selection never mentionedA voice binds to an element and travels with the character between generations, which is the half vendors usually fail. Where the voice came from, and whether a production can choose it, is the half usually documented and here is blank.What the guide saysWhat it never saysDoes the voice lastIt belongs to the elementWhether it can be changedWhere it came fromNothing on originNo catalogue, sample or previewCan it be auditionedNothing on hearing it firstWhat the first generation will giveIf you supply oneNo input is describedSo no conflict is described eitherThe harder half answered, the easier half left out

Inclusion rule. Only statements found on the vendor page named in the caption, and only ones bearing on this one field. Nothing here is filled in from generated output. Order. In the order the statements arrive on the vendor's page.

1Persistence without selection is half a casting system

This entry solves the harder half of the problem and leaves the easier half blank. A voice that survives a season is the part vendors usually fail at; being able to pick the voice in the first place is the part they usually document. Here it is the other way round.

For a production the consequence is a cast assembled by accident. The characters will sound consistent, and nobody can say in advance what any of them will sound like, which makes the first generation of each character a casting session with one candidate.

2Nothing in the guide describes a conflict, because nothing can be supplied

Several entries in this register have to explain what happens when a supplied clip disagrees with a stored voice. This one does not need to, because there is no documented input. That is internally consistent and it removes a lever a director would expect to have.

Recorded as unstated rather than as absent. A platform with an element system almost certainly has some way to influence a voice; the guide that a production reads before committing does not describe one.

3The others that publish nothing a production could hand over

Six more entries reach this column with nothing in it. Two of them, like this one, do bind a voice to something durable while never saying what the voice is.

  • LTX Studio — nothing documented as an input.
  • Luma Ray — nothing documented as an input.
  • Sora 2 — nothing documented as an input.
  • sync-3 — nothing documented as an input.
  • Veo — not documented by the vendor.
  • Vidu — nothing documented as an input.
