Can MiniMax H3 Use Audio References?

Overview

Some MiniMax H3 routes accept audio input to guide the sound of a generated video, but the exact behavior — voice, soundscape, or dialogue reference — depends on the version, so verify it before designing a workflow around it. What counts as a supported audio reference is not the same on every platform.

Know which job you are actually asking for. A soundscape reference shapes ambient mood and is fairly low-risk. A voice reference is different and far more sensitive, because using someone’s voice raises consent and rights questions that an ambient soundscape does not. If you plan to reference a real person’s voice, get clear, documented permission first and confirm the provider allows it; skipping that step is a legal risk, not just a quality one, and it does not get cheaper after the fact.

Prepare clean audio the way you would a clean image reference: trim it to the relevant segment, reduce background noise, and match it to the scene you are generating. A tidy few seconds guides the model better than a long, noisy file where the signal you care about is buried.

Audio features move fast in this model family, so re-check the current docs before each project, and keep permission records for any real-person voice you use in case anyone asks later.
