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.
