美得得-声音克隆QWEN

描述

本接口支持声音克隆和音色创造两种能力,基于少量音频样本或文本指令生成目标音色的语音(Text-to-Speech)。

  • 音色克隆:基于用户提供的 WAV 音频样本克隆声音,再将指定文本合成为该音色的语音。
  • 音色创造:无需提供音频,通过 instruct 描述期望的音色特征,直接创造新音色并合成语音。

params.parameter.task_type 支持 vocal_transformersynth_oncevoice_design,对应四种输入模式。

版本

1.0

图片要求

本接口输入媒体为音频。音色克隆模式(vocal_transformer 不传 instructsynth_once)必须传入音频样本 URL,建议使用 WAV 格式;音色创造模式(vocal_transformerinstructvoice_design)不需要音频样本。本文请求与 SDK 示例采用需要音频样本的 synth_once 模式。
