Speech and voice controls, as each vendor documents them

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

Text to speech here supports built-in voices and custom voices created from supplied sample audio, and whichever is chosen travels as a speaker id on the generation request. Two routes, one handle. As of 2026-09-22.

One speaker id, two possible origins behind itA built-in voice and a custom voice built from a supplied sample 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 sample's termsWhatever permission the recordingcarried, tracked only by youSame field on the request, different obligations

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 published ceilings are for the call, not for the sample

Sixty seconds and a hundred megabytes are documented for audio and video on the generation request. Nothing states how long a sample the custom-voice 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

Four more entries answer with something to choose from. This one and two others also accept a recording, so the catalogue is a starting point rather than the whole answer.

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