## Positioning

ElevenLabs v3 is a text-to-speech model optimized for high-fidelity, emotionally expressive audio generation. Reach for it when voice quality, pacing control, and multilingual coverage matter more than raw throughput or latency.

## About

ElevenLabs v3 generates speech from text input with support for emotional range, inline audio tags, and natural delivery across more than 70 languages. It operates at a medium speed tier with a balanced cost profile and a 5,000-token context window.

On Kyma, the model runs through an OpenAI-compatible endpoint with automatic failover to maintain delivery if a serving path degrades. It supports prompt caching, which bills repeated prompt prefixes at 10% of the standard input rate. Responses return exact billing data in usage.cost and identify the executed model via the X-Kyma-Model header.

The model does not support reasoning, vision, or structured outputs. It is strictly a speech generation engine, so it will not process images, execute code, or return JSON schemas.

## Use cases

- **Premium Voiceover Production** — Generate broadcast-quality narration with controlled emotional pacing and tone.
- **Character Dialogue Generation** — Produce distinct, expressive voices for interactive fiction or game assets.
- **Multilingual Audio Localization** — Convert scripts into natural-sounding speech across more than seventy languages.
- **Emotional Audiobook Narration** — Render long-form text with dynamic inflection and audio tag directives.

## Not ideal for

Do not use this model for real-time conversational speech or high-throughput batch processing where latency and cost efficiency are the primary constraints.

## Pick something else when

- You need faster, lower-latency speech generation → `eleven-flash-v2-5`
- You require custom voice cloning or voice design → `minimax-voice-clone`, `minimax-voice-design`
- You need background music or sound effects instead of speech → `elevenlabs-music`, `elevenlabs-sfx`
