Qwen3 TTS Voice Design | AI Text-To-Speech With Custom Voice Description

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.

Pro Tips

Be specific in your voice description — include age, gender, emotional tone, speaking pace, and any accent preferences.
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.
