The text-to-speech models support over 90 languages, inline emotion prompting, and a median time to first speech of ~150ms on the Turbo variant.
- Supports natural language inline audio tags for emotions, accents, and sound effects, alongside improved IPA phoneme support.
- Eleven v4 Turbo achieves a median inference latency of ~100ms for conversational agent workflows.
- Instant Voice Clones can replicate voices using 10 seconds of audio while maintaining speaker identity across language switches.
