What is the difference between TTS-VC and TTS-VD?

VC (Voice Cloning) copies an existing voice from an audio file. VD (Voice Design) creates a brand new voice from a text description (e.g., "Make a voice that sounds like a scary pirate").

Can I save the voice I designed?

Yes, once you generate a voice you like via the API, you get a "Voice ID" that you can use in future calls to make that specific character speak new text consistently.

How detailed can the prompts be?

Very detailed. You can specify age ranges (e.g., "Child 5-12"), specific emotions ("calm," "excited"), speaking rates ("fast," "slow"), and even textural qualities like "raspy" or "sweet."

Is TTS-VD-Flash expensive?

It follows the standard Alibaba Cloud pricing model, which is generally competitive (often billed per million characters). There is a free quota for new users to test the capabilities.

About This AI

Qwen3-TTS-VD-Flash (Voice Design) is the generative “sister” model to the voice cloning tool, designed to create entirely new, non-existent voices from pure text descriptions.

Instead of needing a reference audio file to clone, users can simply type a prompt like “An energetic young female news anchor with a crisp tone” or “A raspy, middle-aged wizard whispering a secret,” and the AI generates a unique voice matching those characteristics.

It leverages the same “Flash” architecture for ultra-low latency, making it ideal for creating dynamic characters in games, audiobooks, and virtual assistants where a specific persona is needed but no voice actor exists.

Key Features

Natural Language Voice Prompts: Create complex custom voices by describing attributes such as gender, age, pitch, speed, and personality (e.g., "magnetic," "cheerful," "serious").
No Audio Reference Needed: Frees users from finding sample audio; simply "design" the voice you imagine using text.
Fine-Grained Control: Supports detailed instructions on "how to say it," adjusting prosody and emotion based on the semantic content of the script.
Multilingual Synthesis: Once a voice is designed, it can speak fluently in 10 supported languages (English, Chinese, Japanese, etc.) without losing its character.
Role-Play Optimization: Specifically tuned for role-play scenarios, outperforming competitors like Gemini 2.5 Pro TTS in character consistency benchmarks.
High Stability: Maintains the same voice identity across long sessions, preventing the "voice drifting" common in other generative audio models.

Pros

Infinite variety of unique voices without copyright issues.
"Flash" speed allows for real-time interaction in chatbots.
Exceptional adherence to complex descriptive prompts.
significantly cheaper than hiring voice actors for every minor role.
Solves the "cold start" problem (no need for a reference clip).

Cons

Requires access via Alibaba's API (not fully local).
Describing a voice accurately in text can sometimes be trial-and-error.
While "expressive," it may still lack the specific "acting choices" of a human professional.

Best for Game developers creating NPCs, audiobook publishers needing distinct narrator voices, and brand managers looking for a unique “sonic identity” for their AI agents.
