• create_training_job

  Creates a private NiceVois job and returns a one-time PUT upload URL. Do not ask for consent before the first attempt because NiceVois remembers the current standing account agreement. If the server returns CONSENT_REQUIRED, ask for one acceptance of the linked standing…

• start_training

• create_voice_model_import

• create_voice_conversion

  Use this when the user has selected a private voice model and wants to convert one vocal recording. Returns a private upload instruction. Upload only the source vocal, then call get_voice_conversion with the same conversion ID. Creating it counts one of the account's conversions…

• get_voice_conversion

  Use this when checking one private NiceVois conversion. Poll no more than once every 10 seconds. Report the returned stage without inventing progress. When complete, present the NiceVois cleaned version first and use download_voice_conversion_output for the version the user…

• download_voice_conversion_output

  Use after get_voice_conversion says the job is complete and the user wants the cleaned or standard output. Downloads are free; the conversion was counted once when it started. If the exact file was downloaded before, ask before retrying and then set confirmRepeat true.
