Async Workflow
This model uses asynchronous execution. Submit a request and poll for the result.
- Submit — POST to /v1/run, receive an

ElevenLabs V3
Eleven v3 is an expressive text-to-speech model for performances that require more than neutral narration. It interprets inline audio tags and textual context to shape emotion, pacing, delivery, reactions, and non-verbal vocal behavior, making scripts sound directed rather than simply read aloud.
The model is suited to dialogue, character work, audiobooks, localization, and dramatic voiceover across a broad multilingual range. It can distinguish speakers in structured dialogue and produce nuanced delivery such as whispers, laughter, hesitation, excitement, or tension within the same scripted performance.
Highlights
Audio-tag direction. Uses inline cues to control emotion, delivery, reactions, pacing, and non-verbal vocal behavior.
Expressive performance. Produces nuanced speech that can whisper, laugh, hesitate, intensify, or shift mood within a passage.
Multi-speaker dialogue. Handles structured conversations with differentiated voices and natural turn-taking.
Broad multilingual speech. Supports expressive narration and localization across a wide range of languages.
Pricing
| Text allowance | Price |
|---|---|
| Each started block of 1,000 characters | $0.100 |
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.
