Verdicts

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.

PlayHT Voice Cloning API

The API reference is still readable at docs.play.ht, useful for mapping old integrations. Shut down, api.play.ht doesn't resolve.

Before you call either

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

PlayHT Voice Cloning API

  1. Don't call api.play.ht. The host doesn't resolve
  2. Ignore docs.play.ht for new work. It documents an API that no longer exists
  3. Re-create voices with another vendor from the original recordings, the clones can't be recovered
