Speech and voice controls, as each vendor documents them

PixVerse: a built-in voice, or one made from your recording

The speaker list returns built-in voices and the account's custom voices, and a separate call makes a custom one from an uploaded recording. Whichever is chosen travels as a speaker id on the lip-sync request. Two routes, one handle. From 3 source pages, read 2026-10-25; no maker pays to be listed.

One speaker id, two possible origins behind itA built-in voice and a custom voice made from an uploaded recording are both passed as a speaker id, so the request looks identical either way and nothing in a log distinguishes a licensed catalogue entry from a clone.What sits behind a speaker idA built-in voiceThe platform's termsLicensed by the vendor, reusable withouta releaseA custom voiceYour recording's termsWhatever permission the recordingcarried, tracked only by youSame field on the request, different obligations

What the documentation settlesWhat it leaves to a take
The speaker list returns built-in voices and custom voices, and can be filtered to eitherWhether a custom voice appears there as soon as the creation call returns
A custom voice is created from an uploaded audio resourceHow long a recording the custom route needs, since no window is published
A speaker id taken from the TTS list is passed on the lip-sync requestWhether a custom speaker id persists between projects

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.

1One handle for two very different origins

A speaker id that might point at a stock voice or at a clone of a real performer is convenient in code and risky in a production. The request looks identical either way, so nothing in a log distinguishes a licensed catalogue voice from one built out of somebody's recording.

That matters for the same reason the distinction matters legally. A stock voice carries the platform's terms; a custom one carries whatever permission the sample came with, and only a production's own records connect an id to that.

2The creation call states no sample window

The page says a custom voice is made from an uploaded audio resource and shows that the call returns a speaker id. Nothing states how long a recording the route wants, which is the figure a casting decision needs, and it is the one figure this otherwise specific page leaves out.

Comparing across this column, published sample windows range from a single recording to twenty minutes of studio time. Without a figure here, a production cannot tell which end of that range it is being asked for.

3The others that hand a production a catalogue

Three more entries answer with something to choose from. This one also accepts a recording, so the catalogue is a starting point rather than the whole answer.

  • D-ID — a voice id, or a recording by url.
  • SceneMixer — a preset library, or the user's own recordings.
  • Synthesia — a catalogue voice, or a cloned one.
  • Voice source
