Tips for natural-sounding audio

  • Add punctuation and paragraph breaks to improve pacing and rhythm.
  • Use commas and ellipses to create natural pauses in the speech.
  • Test different voices on a short sample before generating a long script.
For longer scripts, ElevenLabs voices deliver the most natural results, while Speechify is more credit-efficient for high-volume generation.

Credit usage
