How Does API Work?

The process to transcribe an audio file:
  • Post the request by:
    • Enter the valid REV-APPNAME, REV-APP-ID, and REV-API-KEY.
    • Define the Language Code and domain.
    • Upload the audio file to transcribe.
    • Define the audio format, if required.
  • The API will return the text in the requested Indian language.
