U2-TTS-Design: Design your exclusive voice with text
U2-TTS-Design does not require uploading real-person samples or picking from a fixed voice library. Simply describe the voice you want in natural language (e.g. gender, age, pitch, speed, emotion, accent, texture, character personality, use case), and it can generate a reusable exclusive voice from scratch.
Core Advantages
Core Advantages
Zero reference audio, text-only voice creation
No real-person samples, no recording sessions, no professional post-production. Customize a new voice entirely through text descriptions — easy even for beginners.
Full-dimensional voice control
Freely customize gender, age, pitch, speed, emotional tone, dialect accent, character personality, and fine-grained parameters to match your vision.
Generate once, reuse forever
Each generated voice has a unique ID that can be saved long-term and invoked anytime across multiple scripts, businesses, and scenarios with consistent voice identity.
Original and compliant, avoiding copyright risk
Focuses on creating entirely new voices without replicating real people or public figures, avoiding voice infringement and portrait-right disputes for safer enterprise use.
Fast iteration, simplified workflow cost
If the voice is unsatisfactory, simply revise the text description and regenerate — saving time, labor, and communication costs compared with dubbing, sampling, and repeated tuning.
Technical Highlights
Technical HighlightsMore freedom in voice design
Not limited to preset system voices or user audio samples — create brand, character, broadcast, narrative, and companion voices directly through natural language.
Finer control granularity
Describe timbre, emotion, rhythm, pitch, accent, tone, character personality, and scenario use in one go — covering multi-dimensional control from voice to performance.
Stronger expression consistency
Created voices can be stored as reusable voice assets, maintaining a stable voice identity across multiple contents, calls, and business lines.
Better suited for compliant original voices
Voice Design emphasizes describing voice traits rather than imitating specific people — ideal for enterprises building original brand voices and character voice libraries.
Synergy with voice cloning capabilities
First design an ideal base voice style through text, then connect with platform voice cloning for personalized refinement — ideal for virtual hosts, AI assistants, and game NPCs in long-term content production.
