Write for speech

  • Prefer short sentences and pronounceable wording.
  • Spell out uncommon abbreviations when pronunciation matters.
  • Use line breaks to separate changes in thought or tone.
  • Generate a short sample before committing to a long script.
When speech is one part of a larger creative task, generate or upload it first, then add it as an audio reference in the same Space.
