Features

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.

Parameters

Voice Description Examples

• “A young female voice, energetic and cheerful, speaking quickly with enthusiasm”
• “An elderly male narrator with a deep, calm, authoritative tone”
• “A professional newsreader voice, neutral and clear, with perfect pronunciation”
• “A warm, friendly customer service representative, patient and helpful”
• “A dramatic storyteller voice with expressive intonation and theatrical pauses”

How to Use

1. Enter your text — write or paste the content you want to convert to speech.
2. Describe your voice — use natural language to describe the voice characteristics you want (age, gender, tone, style, accent, etc.).
3. Select language — choose the target language or use “auto” for automatic detection.
4. Run — submit and download your audio file.

Pricing

Billing Rules

• Minimum charge: $0.02 (for texts under 1,000 characters)
• For longer texts: $0.02 × (character count / 1,000)

Best Use Cases

• Character Voices — Create unique voices for games, animations, or audiobooks without voice actors.
• Prototyping — Quickly test different voice styles before committing to production.
• Localization — Generate consistent voice styles across multiple languages.
• Accessibility — Convert text to speech with customized, natural-sounding voices.
• Content Creation — Produce voiceovers for videos, podcasts, and presentations.

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.
