Overview
This model converts text input into audio output with support for expressive voice profiles and brand-safe delivery. It operates in a balanced cost tier with medium generation speed and is designed specifically for speech synthesis. On Kyma, it runs through an OpenAI-compatible endpoint using a single API key. This model does not support prompt caching. Requests automatically failover to healthy serving paths if degradation occurs, and exact billing details are returned in the usage.cost field. The model does not support reasoning, vision, or structured outputs. It accepts text input only, has a 5,000-token context window, and is strictly an audio generation endpoint.Specs
Pricing
Billed per character of input text. Every request reports its exact cost in
usage.cost; the full media price list is on Pricing.
Use this when
- Multilingual Voiceover Generation — Produce localized audio tracks for videos and presentations across 29 supported languages.

- Text Translation to Speech — Convert written translations into natural-sounding audio for accessibility or localization workflows.
Not ideal for
Do not use this model for tasks requiring text reasoning, structured JSON output, or ultra-low latency streaming, as it only generates audio and operates at a medium speed tier.Pick something else when
- You need faster audio generation for real-time applications: use
eleven-turbo-v2-5orminimax-speech-turbo. - You require ultra-low latency at a lower cost tier: use
eleven-flash-v2-5.
