| Parameter | Type | Required | Description |
|---|---|---|---|
text | string | Optional | The text to convert to speech · Min length: 1 |
speed | number | Optional | Speech speed (0.7-1.2). Values below 1.0 slow down the speech, above 1.0 speed it up. Extreme values may affect quality. · Min: 0.7 · Max: 1.2 · Default: 1 |

language_code | string | Optional | Language code (ISO 639-1) used to enforce a language for the model. · Options: , en, ja, zh, de, hi, fr, ko, pt, it, es, id, nl, tr, fil, pl, sv, bg, ro, ar, cs, el, fi, hr, ms, sk, da, ta, uk, ru enjazhdehifrkoptitesidnltrfilplsvbgroarcselfihrmsskdataukru |
Output Schema
| Field | Type | Description |
|---|---|---|
id | string | Unique identifier for the generation task |
status | string | Task status: pending, running, completed, failed, timeout |
model | string | Model used for the generation |
outputs | array | Array of output items |
outputs[].url | string | URL of the generated artifact |
outputs[].content_type | string | MIME type (e.g. image/png, video/mp4) |
error | object | null | Error details if failed, null on success |

Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an
id - Poll — GET /v1/run/{id} until status is
completed,failed, ortimeout - Retrieve — Read

Multilingual V2
elevenlabs/multilingual-v2 synthesizes expressive speech across a broad multilingual set while preserving a selected voice's recognizable character between languages. Multilingual V2 emphasizes natural cadence, emotional delivery, and long-form stability rather than the lowest possible latency, making it well suited to polished narration and localized storytelling. This combination makes the model a practical choice when the creative outcome depends on those qualities rather than on a generic media conversion.
For production work, Adjustable stability and speaking speed let producers balance expressive variation against consistency across chapters, lessons, explainers, and translated campaign material. The result is most reliable when the source material and creative brief clearly describe the intended subject, progression, visual or sonic character, and the qualities that must remain unchanged.
Highlights
Cross-language voice consistency preserves a chosen speaker identity across multilingual delivery.
Natural prosody supports expressive pacing, emphasis, and emotional narration.
Long-form stability keeps tone and pronunciation coherent across extended scripts.
Broad language coverage supports localized narration from one speech model.

When to Use
| ✅ Good fit | ❌ Consider alternatives |
|---|---|
| The model's named workflow matches the source material and intended output | A different input modality or model route is required |
| A managed asynchronous result is suitable for the production pipeline | A synchronous, interactive editor is essential |
| The documented controls cover the required duration, framing, or format | The project needs controls outside this endpoint's schema |
| Creative iteration benefits from a repeatable request structure | Exact deterministic pixels, frames, geometry, or samples are mandatory |
| A finished downloadable media asset is the desired deliverable | Editable source layers or a native project file are required |
Prompt Guide
For generation, state the intended result first, then add the subject or source treatment, progression, style, and delivery constraints. Keep one creative variable per phrase, use the documented field names for controls, and change one setting at a time when comparing results.
