Speech and voice controls, as each vendor documents them

What Kling AI documents about speech

Kling AI (kling.ai), an AI creative studio, documents native audio on VIDEO 3.0 in five languages and binds a voice to an element, so a character keeps its voice across generations. From 1 source page, read 2026-09-12; no maker pays to be listed.

Inclusion rule. Fields are the same five for every model here; a field the vendor does not document is recorded as not documented rather than inferred from generated output. Order. Fixed field order, identical on every model page.

1Binding a voice to a character, not to a call

The element system is what makes this entry different from the others. A character defined once as an element carries its voice with it, which means the voice is a property of the character rather than something re-specified on every generation. For a serial production that is the difference between a cast and a series of coincidences.

What the guide does not give is a way to audition or pin a specific voice: the five languages are a count rather than a list, and no voice identifiers appear. A production can therefore rely on the voice staying the same without being able to say in advance what it will be.

2Lip-sync is claimed without a mechanism

Lip-sync appears in the documentation as a capability. Nothing states whether it is driven by the generated audio, by the text, or by a separate pass, and nothing states what happens with two speakers in frame. Those distinctions decide whether a dialogue scene can be shot in one generation, so they are recorded as unstated rather than assumed.

The same silence covers what happens when a supplied voice conflicts with the element's bound voice. Where a vendor documents a hierarchy, this site records it; Kling does not.

3This entry, one column at a time

Each of these stays inside a single field: what Kling AI puts there, what the wording settles, and what it leaves for a take to answer.

4Read against another entry

Each of these puts Kling AI beside one other entry on a column where the two land at opposite grades of answer.
