# MiniMax Audio Quick Cloning

This API supports cloning voices from mono or stereo audio, enabling quick replication of speech with the same timbre based on a specified audio file.
The quickly cloned voice produced by this API is a temporary voice. If you wish to permanently retain a cloned voice, please use this voice in any T2A speech synthesis API within 168 hours (7 days) (excluding the trial-listening behavior within this API); otherwise, the voice will be deleted.

Applicable scenarios for this API: IP replication, voice cloning, and other scenarios that require quickly replicating a specific voice.

Notes:

* The uploaded audio file format must be: mp3, m4a, or wav;
* The uploaded audio file must be at least 10 seconds long and no longer than 5 minutes;
* The uploaded audio file size must not exceed 20mb.

## Request Headers

<ParamField header="Content-Type" type="string" required={true}>
  Enum value: `application/json`
</ParamField>

<ParamField header="Authorization" type="string" required={true}>
  Bearer authentication format: Bearer \{\{API Key}}.
</ParamField>

## Request Body

<ParamField body="audio_url" type="string" required={true}>
  The audio file url for the voice to be cloned. Supports mp3, m4a, and wav formats.
</ParamField>

<ParamField body="clone_prompt">
  Voice cloning parameters. Providing this parameter helps improve the timbre similarity and stability of speech synthesis.

  If this parameter is used, you must also upload a short sample audio clip (less than 8s) and the corresponding text for the audio. The audio supports mp3, m4a, and wav formats.

  <Expandable title="properties">
    <ParamField body="prompt_audio_url" type="number" required={true}>
      Audio prompt parameter: the sample audio url. The duration must be less than 8s.
    </ParamField>

    <ParamField body="prompt_text" type="string" required={true}>
      Audio prompt parameter: enter the corresponding text for the sample audio. Make sure it matches the audio content, and the sentence must end with punctuation.
    </ParamField>
  </Expandable>
</ParamField>

<ParamField body="text" type="string">
  Cloning trial-listening parameter. The model will read this text using the cloned voice and return the synthesized audio result as a link for previewing the cloning effect. Limited to 2000 characters. Note: trial listening will be charged for speech synthesis based on the number of characters, with pricing consistent with the T2A APIs.
</ParamField>

<ParamField body="model" type="string">
  Cloning trial-listening parameter. Specifies the speech model used for trial listening. This field is required when the "text" field is provided.<br />
  Options: `speech-2.8-hd`, `speech-2.8-turbo`
</ParamField>

<ParamField body="accuracy" type="float">
  Audio cloning parameter. Value range: \[0,1]. Providing this field sets the text verification accuracy threshold. If not provided, the default value is 0.7.
</ParamField>

<ParamField body="need_noise_reduction" type="bool">
  Audio cloning parameter. Whether to enable noise reduction. Defaults to false if not provided.
</ParamField>

<ParamField body="need_volume_normalization" type="bool">
  Audio cloning parameter. Whether to enable volume normalization. Defaults to false if not provided.
</ParamField>

## Response Information

<ResponseField name="demo_audio_url" type="string">
  If the request body includes the trial-listening text text and the trial-listening model model, this parameter returns the trial-listening audio as a link.
</ResponseField>

<ResponseField name="voice_id" type="string">
  The generated voice\_id
</ResponseField>
