Overview

ElevenLabs TTS v3 turns text into speech audio with a selected voice ID using ElevenLabs Turbo v3. Use it for fast voiceover drafts, narration, ad reads, podcast segments, and product-demo scripts when audio tags, language selection, speed, continuity text, and character-level timing matter.

Use cases

  • Generate speech for product demos, ads, explainers, or podcast segments from a script.
  • Use audio tags such as [laughing], [whispering], [pause], or direction cues to shape delivery.
  • Produce character-level timing JSON for captions, lip-sync prep, or audio-text synchronization.
  • Use previous_text and next_text to smooth delivery across separately generated script sections.

Input tips

  • Keep text under 5,000 characters.
  • Provide a valid ElevenLabs voice_id from available default or custom voices.
  • Set language only when Turbo v3 should enforce a specific language.
  • Use stability, similarity_boost, and speed to tune the voice; v3 does not support style or speaker boost.
  • Choose output_format only when a specific audio handoff format matters; otherwise use the default.
  • Use audio tags, dashes, and ellipses sparingly so the script stays natural.
  • Use seed for repeatability, but treat it as best effort.

Expected output

The AI Tool returns one generated speech audio file with downloadable URL, content type, optional file size, alignment JSON URLs when available, and cost metadata. The shared ElevenLabs TTS view renders an audio player and download links for character-level timing and normalized timing when present.

Caveats

  • Voice IDs must be valid and permitted for use.
  • Generated speech should be reviewed for pronunciation, tone, pacing, and brand fit.
  • Audio tags and direction cues influence delivery but may not land exactly.
  • Turbo v3 does not include Multilingual v2's style exaggeration or speaker boost controls.
  • Seeded generation is best effort; exact determinism is not guaranteed.
  • Some requested formats or language settings may fail if unsupported by the selected model.
