Speech and voice controls, as each vendor documents them

Synthesia: a catalogue entry, or a clone with its own reach

Two routes, each documented with a range. The catalogue lists every voice with a language name, a code, a gender, a name and an id. Cloning carries a separate list, described as the same one used for standalone cloning. As of 2026-09-22.

Two published ranges, and why they stay separateThe catalogue lists voices the platform supplies, structured enough to filter by language code and gender. Cloning carries a different range, described as the standalone cloning list from Afrikaans to Zulu.The catalogue routeThe cloning routeWhat you getA voice the platform already ownsA voice built from a recordingHow it is publishedPer voice: language, code, gender, idAs a range in proseCan it be shortlistedYes, before any commitmentNot from the pageWho carries permissionThe platformWhoever was recordedReading only one of the two misjudges the reach

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.

1A browsable inventory, which is rare in this column

Everywhere else in this register a catalogue is asserted or hidden behind an endpoint. Here it is published per voice with enough structure to be filtered: a language code, a gender and a stable id. A production can shortlist before it signs anything, which is the difference between choosing a voice and discovering one.

Structure also makes the inventory auditable over time. An id that disappears is visible; a voice quietly replaced behind a claim of broad support is not.

2Two routes with two ranges is a distinction worth keeping

The catalogue and the cloning list are not the same list, and the cloning one is described in the sweeping terms the catalogue avoids. A production reading only one will misjudge its reach, in whichever direction it happened to read.

The register keeps them separate for that reason. Two published ranges collapsed into a single number is the error this column exists to prevent, and it is an easy error to make because both sentences sit near each other on the vendor's pages.

3The others that hand a production a catalogue

Four more entries answer with something to choose from. This is the only one whose inventory is published in enough structure to be filtered before any commitment.

  • D-ID — a voice id, or a recording by url.
  • Hedra — a track, or a voice id from the endpoint.
  • PixVerse — a sample, or a built-in voice.
  • SceneMixer — a preset library, or the user's own recordings.
