About the Model

为什么要选择 MiMo Voice Design 2.5?

这是一种颠覆传统的语音合成方式,它完全摒弃了传统的“选定音色”和“提供音频克隆”的思路,能够做到“无中生有”。

核心优势与特点

  • 自然语言捏制声音:您只需要输入类似于『粗犷、带点口音的中年大叔,说话直来直去』这样的文本描述,大模型就能根据语义理解直接生成出一个世上独一无二的声音。
  • 导演模式控制:支持通过提示词控制人物的背景、当下的场景、甚至是特定的演绎风格,给内容创作提供了无尽的想象空间。
  • 零样本需求:您甚至不需要准备几十秒的干净音频,彻底打破了素材限制。

How to Access for Free (via Xiaomi)

免费依据 (Why is it free?)

此创新功能作为 MiMo 平台吸引创作者体验的入口产品,现阶段开放全额度限时免费。由于生成特定高质量声音的算力成本较高,建议尽早利用此免费红利期产出内容。

【额外福利】虽然本模型本身免费,如果您还想体验小米的其他付费顶尖模型(如 MiMo V2.5 对话模型),我目前正在使用 MiMo 开放平台,通过我的邀请码注册为新用户,即可获得 $2 API 体验金。 • 邀请码:TUE76X • 注册链接:https://platform.xiaomimimo.com?ref=TUE76X • 兑换方式:注册后点击控制台左下方入口填入,体验金 40 天有效。
