What PixVerse documents about speech
PixVerse (docs.platform.pixverse.ai) documents a speech endpoint taking either a supplied clip or a text-to-speech voice, caps audio and video at sixty seconds each, and names singing and advertising alongside speech as the kinds of audio it expects. As of 2026-09-22.
| Field | What the vendor documents |
|---|---|
| Audio source | Supplied to a speech endpoint, or read from text there |
| Languages | Multiple, with speech, singing and advertisements named as types |
| Voice source | Built-in voices, or a custom voice from a supplied sample |
| Per-character binding | A speaker id passed on the generation request |
| Lip-sync | The purpose of the endpoint; no mechanism given |
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.
1Types of performance, not just languages
The guide says what the endpoint is for by kind of audio: speech, singing and advertisements. That taxonomy carries more about the expected work than a language count would, because a sung line and a read line put different demands on a mouth, and a vendor naming both has at least considered the harder one.
Languages are described only as multiple. A production can therefore learn that the feature is not English-only and cannot learn whether its own market is covered, which is the shape most language claims in this register take.
2Sixty seconds, on both sides of the call
Audio and video are each capped at sixty seconds and one hundred megabytes. A ceiling on both inputs hints at how the feature is meant to be used: a scene gets synchronised a beat at a time, and a long monologue becomes several calls whose joins somebody has to manage.
It is also a number to schedule against. Where an entry publishes a ceiling an editor can plan the cut; where it publishes none, the ceiling is discovered at the render.
3Two kinds of voice behind one handle
Text to speech supports built-in voices and custom voices created from user-provided sample audio, and either way the choice becomes a speaker id on the request. That single handle is convenient and it flattens a distinction worth keeping: a catalogue voice is repeatable by anyone, while a custom one depends on a sample somebody has to keep safe.
Nothing states how an id is held to a character over a series, so the binding is recorded as a per-call selection. It is a workable pattern as long as the mapping lives somewhere outside the call.
4This entry, one column at a time
Each of these stays inside a single field: what PixVerse puts there, what the wording settles, and what it leaves for a take to answer.
- Audio source — supplied, or read from text.
- Voice source — a sample, or a built-in voice.
- Per-character binding — on the request.
- Languages — multiple, none of them named.
- Lip-sync — named as the endpoint's purpose.
5Read against another entry
Each of these puts PixVerse beside one other entry on a column where the two land at opposite grades of answer.
- PixVerse and D-ID — on per-character binding.
6Where this model sits against the rest
| Model | Audio source |
|---|---|
| D-ID | A text script read aloud, or an audio url supplied |
| Hedra | Supplied; audio is a required input |
| HeyGen | A text to speech endpoint, apart from the picture |
| Kling AI | Generated with the picture, VIDEO 3.0 |
| LTX Studio | Generated jointly with the picture, plus audio-to-video |
| Luma Ray | Not documented; the video reference does not mention sound |
| MiniMax | Native speech, generated with the picture |
| PixVerse | Supplied to a speech endpoint, or read from text there |
| Runway | Not documented where voices are defined |
| SceneMixer | Generated with the picture, in the language set for the project |
| Sora 2 | Generated with the picture; video and audio are both listed as output |
| sync-3 | Supplied, or read from text on the call |
| Synthesia | Synthesised from the script, or an uploaded recording |
| Veo | Generated with the video rather than added afterwards |
| Vidu | Q3 generates speech, effects and music natively, on by default |
| Wan 3.0 | On by default; false returns a file with no audio track |
| Wan2.2-S2V | Supplied; the card describes the model as audio-driven |
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.
