  • Enable english_normalization when your text contains numbers, dates, or currencies.
  • Use pronunciation_dict for consistent handling of brand names or technical terms.
  • Start with default speed/pitch settings, then adjust based on your specific use case.

Notes

  • Text length affects processing time and cost — longer texts take more time.
  • For custom voices, train your voice model first via Voice Clone.
