MiMo V2.5 TTS VoiceDesign

VoiceDesign creates a new voice from a written description. It does not need a preset voice or an uploaded sample.

Describe the sound rather than studio processing

The guide accepts Chinese or English descriptions. It recommends concise, non-conflicting voice traits and warns against treating effects such as reverb or equalization as voice characteristics.MiMo V2.5 speech synthesis guide

Keep identity and delivery separate

Practical guidance. Describe a stable voice identity first, then adjust pace or emotion for the script. Compare several samples before choosing a voice. A description that works for a calm narration may need different delivery instructions for an urgent announcement.
