Watch out for
  • Less expressive at the top end
  • No custom voice cloning
  • Cloning a real employee’s voice requires their written consent
  • Several jurisdictions require candidates to be told they are speaking to a machine — build the disclosure into the script, not the footer
  • Per-character pricing makes long calls expensive in a way per-minute pricing hides
