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.
Interjections must be written in parentheses exactly as listed to be recognized.
