Speech and voice controls, as each vendor documents them

Entries handed a recording and asked to fit a picture

Two entries are driven by audio a production supplies. Nothing is generated until a recording exists, which lengthens the front of a schedule and hands a director something to approve before any rendering is paid for. From 2 source pages, read 2026-09-22; no maker pays to be listed.

A schedule that runs backwards, and what that buysNothing is generated until a recording exists, so casting, a session and a delivered file sit in front of the first frame. In exchange a director approves the performance before any rendering is billed.Cast and recordA performer anda session, bothbefore anythingis rendered.A fileApproveThe performanceis signed offwhile changesare stillcheap.An approved takeGenerateThe picture isfitted to theaudio, and thedriver isalways named.Picture onlyReviseVisual fixesleave theapprovedperformanceuntouched.

Inclusion rule. Entries whose documentation describes audio as an input that drives the generation. Entries that synthesise speech from a script in a separate step are on their own route page, because the recording session is the part that differs. Order. Alphabetical by model name.

1Every entry here names its driver, and that is not a coincidence

When the waveform is an input, saying the mouth follows it costs the vendor nothing: it is a description of the interface rather than a promise about a model's internals. Both of these publish a driver statement, and only two entries elsewhere in the register manage one.

That makes this group the easiest to plan around and the hardest to shortcut. The alignment question is settled on the page; the recording question is entirely a production's own, and no parameter will help with it.

2Approval moves to the front, and so does the cost of a change

A director signs off a performance before a frame is billed, which is the strongest argument for this arrangement. The counterpart is that a line change is a re-record, and a re-record is a room, a performer and a diary rather than a call.

3Both start from a picture made somewhere else

Products on this page operate on material: a still, a reference image, or existing footage. They sit late in a pipeline and assume something else made the picture or the portrait, which is a scheduling fact rather than a limitation.

It also explains why voice inventories are thin here. A team reaching this stage usually already has its audio, from a session or from whichever speech service it standardised on, so a catalogue would go unused.

5Speech, generated with the picture

For the speech side of “Handed a recording”, SceneMixer's guides describe how lines are spoken:

Each line is generated with the picture, in the voice chosen for that character, and the speaker's lips move with the words.

SceneMixer, Dialogue Lines: Delivery Notes, Voice-Over, Captions and the Voice Tag — “Is the dialogue really spoken in the video?” (read 2026-10-13)

SceneMixer writes dialogue into the script analysis, assigns each line to a shot with a speaker and a short delivery note, and the video model performs it — picture and audio generated together, so the mouth forms that sentence in the language you chose.

Membership of this route is decided by the wording in the field it groups by, read from the documentation each vendor publishes. The column itself is on the field note, all five columns are on the speech table, and what counts as documented is on how read. Other routes: Speech from a script, Nothing published.
