When do you download my file when using TTS API?

Question

  • When is the audio file downloaded for TTS?
  • When is the MP3 file downloaded?
  • When is the WAV file downloaded?

Answer

When using the Text To Speech or Text To Speech Prompt API, Nexmo will download the audio file after the API request has been accepted, but before the call is initiated. This means that the MP3 or WAV file will be downloaded before the call is placed to ensure the file is available and the recipient does not receive a short and/or silent call.
