What Vidu documents about speech

Vidu (platform.vidu.com) documents native audio on Q3 covering speech, sound effects and music, switched on by default in the API, with a mode that returns speech alone. 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.

1A default that decides what most output sounds like

Audio being on by default is a small sentence with a large effect. Every call made without reading the parameter list returns a clip with sound, which means the baseline output of this model is a finished soundscape rather than a silent picture waiting for post. A team measuring the model against a silent competitor is not comparing like with like.

The speech-only mode is the counterpart and the more useful one for drama: it separates the line from the effects and music, so dialogue can be kept while the bed is replaced. No other model in this register documents that separation.

2Everything about the voice itself is unstated

Four of the five fields this register keeps are empty here. No language list or count, no statement about where a voice comes from, no way described to hold a voice to a character, and nothing on lip-sync. The API reference describes what is produced and not who is speaking.

For a single clip that is enough. For a series it leaves the central question open, because a cast that is re-drawn on every call is not a cast. This site records the gap rather than filling it from listening tests, which would be an opinion about output rather than a published fact.

3This entry, one column at a time

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

• Audio source — with the picture, speech available on its own.

4Read against another entry

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

• Vidu and sync-3 — on audio source.
• LTX Studio and Vidu — on per-character binding.

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.
