Text Parameter Notes

  • If you POST a string, it'll return a single OutputUri.
  • If you POST a list of strings, OutputUri will be a list of MP3 URLs.
  • For longer texts, we recommend sending a list of strings. This way, instead of waiting for the entire task to be completed to access audio, you can start accessing the first audios in the list. i.e., -.mp3
