How Do I Clone a Voice with MiniMax on WaveSpeedAI?

Overview

You can clone a voice through WaveSpeedAI’s current MiniMax voice-clone route if you have the speaker’s informed permission and the input meets the selected route’s requirements. This is a model access path, not permission to imitate any person or to publish synthetic speech without appropriate disclosure. WaveSpeedAI’s acceptable-use rules prohibit nonconsensual impersonation or deepfake misuse.

Decide the authorized use and record the speaker’s consent first. Then prepare clean source audio, choose an account-unique custom_voice_id, select the supported MiniMax model, and POST those fields to the minimax/voice-clone route with a server-side WaveSpeedAI key. Retain the prediction ID and retrieve the result before publishing any speech. Reusing an existing ID to create a new clone fails; after successful creation, that ID can be used with the supported MiniMax speech models named on the route page.

Review the result for intelligibility, unwanted words, pronunciation and resemblance to the authorized speaker. Put synthetic-voice disclosure and approval into the publishing workflow where required. Do not let a user upload a third party’s clip and assume technical success supplies consent.

If you only need generic narration, a non-cloning text-to-speech route may lower identity risk. Clone a voice when its identity is genuinely necessary and the permission trail is clear.

Before collecting source audio, define who may invoke the clone and how long the generated voice may be used. Restrict access to the resulting identifier, keep an approval log, and remove it from workflows when the authorized use ends. This reduces accidental reuse outside the approved project.
