小米发布 MiMo-V2.5-TTS 系列并开源 MiMo-V2.5-ASR

What makes the MiMo-V2.5-TTS Series different?

It’s not just about generating speech. It’s about making voice controllable, expressive, and usable in real creative workflows. Across the series, the models share three core strengths: 🔹 Strong instruction following — from a single prompt to a full director’s note, they can reliably follow guidance on emotion, tone, pace, delivery, and style 🔹 Flexible audio tag control — inline audio tags let you precisely control emotion, state, and style at specific points in the text, from simple cues to complex multi-tag combinations within the same passage 🔹 Rich text understanding — even with plain text only, the models can naturally pick up rhythm, pauses, emotional shifts, and character cues

On top of that shared foundation, each model is built for a different use case: MiMo-V2.5-TTS High-quality built-in voices, professionally tuned for natural pronunciation and expressive delivery — ready to use out of the box. MiMo-V2.5-TTS-VoiceDesign Generate entirely new voices from natural-language descriptions — no reference audio needed. From age and accent to texture, temperament, and speaking style, the model can turn rich descriptions into distinctive voices, including character voices that don’t exist in any preset library. MiMo-V2.5-TTS-VoiceClone With just a few seconds of reference audio, the model can clone a target voice with high fidelity, with no extra training or fine-tuning. It preserves not only the speaker’s identity, but also personal details like breath, rhythm, and pauses — while still supporting the full control stack of the series.

Whether you need a ready-made voice, a brand-new one, or your own cloned one, MiMo-V2.5-TTS gives you the same thing underneath: voice that can actually follow direction. https://t.co/y5KOMI2GE5
