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. As of 2026-09-12.

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.

• Audio source — with the picture, on video 3.0.
• Voice source — nothing documented as an input.
• Per-character binding — on the element.
• Languages — a count, no names.
• Lip-sync — named, with nothing driving it.

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.

• SceneMixer and Kling AI — on languages.
• Kling AI and Synthesia — on lip-sync.

5Where this model sits against the rest

Inclusion rule. Models whose vendor documents something about generated speech. A model with nothing published on the point is still listed, with the cell marked hollow. Order. Alphabetical by model name.
