Qwen3-TTS Voice Design
Qwen3-TTS Voice Design is a next-generation text-to-speech model that lets you design custom voices using natural language descriptions. Instead of selecting from preset voices, simply describe the voice you want — age, gender, tone, speaking style — and the model generates speech that matches your description.
Why Choose This?
-
Natural language voice control
Describe your ideal voice in plain text (e.g., "a warm, friendly female voice with a slight British accent") and the model creates it.
-
Unlimited voice variety
No preset limits — create any voice character you can describe, from professional narrators to unique personas.
-
Multilingual support
Generate speech in 10 languages: Chinese, English, German, Italian, Portuguese, Spanish, Japanese, Korean, French, and Russian.
-
Auto language detection
Set language to "auto" and the model intelligently detects the language from your text.

- Use descriptive adjectives: "warm", "crisp", "authoritative", "playful", "soothing", etc.
- Mention the context if relevant (e.g., "suitable for a children's audiobook" or "professional corporate presentation").
- Test with short text first to fine-tune your voice description before generating longer content.
- Combine multiple attributes for more nuanced voices (e.g., "middle-aged, confident but approachable").
Notes
- Voice descriptions work best when they are clear and detailed.
- The same voice description will produce consistent results across multiple generations.
- For best quality, match the language parameter to your text content.
