Tools (16)
As the server listed them on Oct 25, 2026. Descriptions are the server’s own words; hidden characters are shown as [U+…].
create_free_audio_jobSplit or clean up audio for freeSplit stems, isolate vocals, or remove noise or reverb. No account needed. Each audio tool includes 10 free minutes every 24 hours; subscribers have unlimited use. Returns an upload URL, then use get_free_audio_job.
create_training_jobCreate an RVC training uploadCreates 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 agreement and retry once with acceptsStandingAgreement=true. This allocates a private training slot but does not start GPU work until the audio is uploaded and start_training is called.
create_voice_conversionCreate an RVC vocal conversionUse 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.
create_voice_model_importPrepare a private RVC model uploadUse this when the user wants to convert with an existing private RVC .pth file or complete model ZIP instead of a voice trained in their NiceVois library. Returns a one-time PUT upload instruction. After uploading, call list_voice_models to select the imported voice.
download_voice_conversion_outputDownload a completed voice conversionUse after get_voice_conversion says the job is complete and the user wants the cleaned or standard output. Each download uses the source audio's duration from the account's conversion-download minutes. If the exact file was downloaded before, ask before retrying and then set confirmRepeat true.
get_conversion_requirementsGet RVC voice conversion requirementsread-onlyUse this when a user wants to convert vocals with RVC or compare a normal RVC result with NiceVois cleaned consonants and breaths. Returns the real input formats, model choices, workflow, current free-beta policy, and outputs.
get_free_audio_jobCheck a free audio jobread-onlyUse this after create_free_audio_job and the upload, no more than every 10 seconds, until the job is completed or failed. When it completes, it lists every output file (for example lead vocal, backing vocals, instrumental) with a download link.
get_training_accountCheck NiceVois training balanceread-onlyCall before quoting or creating a training job. Returns the connected account's welcome-credit status, available and reserved balance, balance packs, and a private browser link that keeps checkout on this same agent identity.
get_training_jobCheck an RVC training jobread-onlyUse this to check truthful stage, completed epochs, ETA, and artifact readiness for one private NiceVois training job. Poll reasonably; do not call more often than every 15 seconds.
get_training_requirementsGet RVC training requirementsread-onlyUse this before training an AI voice to confirm NiceVois input formats, duration and epoch limits, consent requirements, outputs, retention, and the exact upload workflow.
get_voice_conversionCheck an RVC vocal conversionread-onlyUse 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 requests.
list_free_audio_toolsList the free NiceVois audio toolsread-onlyUse this to see NiceVois's free audio tools (no account needed): split a song into vocals and instrumental (vocal remover, acapella, karaoke instrumental), split lead vocals from backing vocals, remove background noise, and remove reverb or echo. Returns each tool's id, the accepted formats, and a website link to give the user when you cannot upload their file yourself.
list_training_jobsList private RVC training jobsread-onlyUse this to find the authenticated user's recent NiceVois jobs before asking for a job ID they may not know.
list_voice_modelsList private RVC voice modelsread-onlyUse this when the user wants to convert audio and you need to select one of their private NiceVois-trained or uploaded RVC voices. Do not ask for a model ID before calling this tool.
quote_trainingQuote an RVC training jobread-onlyCall after inspecting the audio and before creating a job. Returns the exact payable amount, current balance, welcome-credit effect, shortfall, feasibility, and the private balance-page link when more balance is needed.

start_trainingStart RVC trainingUse this only after the source audio was successfully PUT to the upload URL returned by create_training_job. Starts the private cloud RVC training job.
