Verdicts

Fish Audio Voice Cloning API

Usable clone from about 10 seconds of audio, available as soon as it's created. No consent or speaker verification in the API.

MiniMax Voice Clone and Voice Design

Typed OpenAPI files, published prices of $1.50 a cloned voice and $3 a designed voice, and optional transcript and watermark checks. Cloning needs individual or enterprise account verification, the terms and privacy policy could not be read without a browser, and no statement on training with uploaded voice audio was found in the docs.

Before you call either

Fish Audio Voice Cloning API

  1. Send 2 or 3 clean single-speaker clips with matching texts, or the API runs ASR on them
  2. Pass the model _id as reference_id in TTS. Check state before relying on it
  3. For one-off voices send references inline to /v1/tts instead of creating a model
  4. Send the model: voice-design-1 header on voice design calls
  5. Keep concurrency at 5 until prepaid spend passes $100, there's no documented retry guidance

MiniMax Voice Clone and Voice Design

  1. Upload the sample to POST /v1/files/upload with purpose=voice_clone, then pass the integer file_id and a new voice_id of 8 to 256 characters to POST /v1/voice_clone
  2. Synthesise once with T2A within 7 days or the voice is deleted. A preview inside the clone call does not count
  3. Read base_resp.status_code on every response. Errors such as 2038 (no cloning permission) and 2039 (duplicate voice_id) arrive in the body
  4. Voice design returns trial_audio as hex in the JSON body. Write it to a file and keep it out of the model context
  5. Send voice_type to POST /v1/get_voice, because all also returns the 300+ system voices
