Eleven v3

Eleven v3 is a text-to-speech model introduced by ElevenLabs in alpha on June 3, 2025 and taken out of alpha on February 2, 2026. Its official model ID is eleven_v3. It turns text into speech across more than 70 languages, accepts up to 5,000 characters per text-to-speech request, and focuses on emotional range, contextual understanding, and expressive delivery.

Creators can place bracketed audio tags in a script to direct emotion, speaking style, and nonverbal reactions such as laughter or sighs. The Text to Dialogue interface also supports more natural exchanges between multiple speakers. The model remains useful for narrative and character work, while ElevenLabs recommends testing the newer Eleven v4 with your own voices and content to assess audio quality, cloning, and language coverage.

Frequently Asked Questions

How should I handle Eleven v3's 5,000-character limit for an audiobook?

The limit applies to a single text-to-speech request, so split longer chapters at natural paragraph or scene boundaries. Keep adjacent context and voice directions consistent, then listen to the joins for changes in tone or pace.

Can Eleven v3 use SSML break tags for pauses?

No. Eleven v3 does not support SSML <break> tags; use punctuation, text structure, and audio tags to influence pacing, then review the generated pause by ear.

Why does an Eleven v3 audio tag sometimes sound inconsistent?

Results depend on the chosen voice, surrounding text, and tag placement, and a voice may have limited examples of a requested delivery. Put a short, explicit tag near the relevant line and test a few variants with the same voice instead of stacking many directions.

How should I format a multi-speaker script for Eleven v3?

Use the Text to Dialogue interface and submit structured turns for each speaker rather than placing every character in a single-voice text field. The endpoint handles speaker transitions, but review the rendered audio for speaker attribution and emotional fit.

Is Eleven v3 a good fit for a Professional Voice Clone?

ElevenLabs says Professional Voice Clones are not fully optimized for v3, so similarity can be weaker than expected. If voice fidelity matters, compare an Instant Voice Clone, a suitable existing voice, and the newer model using the same script.

Should I use Eleven v3 or Eleven v4?

ElevenLabs recommends testing v4 because it improves audio quality, cloning, tag adherence, and language coverage. An existing v3 project may still have a preferred character delivery; compare the same script and voice under consistent listening criteria before switching.
