Frequently Asked Questions

The Voice Design Studio lets you create custom AI voices by describing characteristics like pitch, speed, warmth, breathiness, and age — no recording needed. The AI generates a voice matching your description using Qwen3-TTS voice design mode.

You adjust sliders (pitch, speed, warmth, breathiness, age) or type a free-text description like "warm, friendly, young female voice with a slight British accent." The AI interprets your description and generates speech in a matching synthetic voice.

Voice design uses Qwen3-TTS in VoiceDesign mode. This model can generate voices from text descriptions without any reference audio. It supports a wide range of voice characteristics and produces natural-sounding speech.

Yes. Once you design a voice you like, click "Save as Preset" to store the description. You can then use this preset across TTS generation, voice chat, and agents — your custom voice is available everywhere.

Voice cloning recreates a specific real person's voice from a recording. Voice design creates an entirely new synthetic voice from a description. Design is faster (no audio needed) and creates unique voices that don't copy anyone.

Pitch (deep to high), speed (slow to fast), warmth (cold/professional to warm/friendly), breathiness (clear to breathy), age (young to elderly), accent (American, British, Australian, etc.), and gender. You can also add custom descriptions for specific traits.

Free accounts can save up to 5 voice presets. Starter plans include 20 presets, and Pro plans include unlimited voice presets. Each preset stores the full description so you can regenerate the exact same voice.

Yes. Voices created through the design studio are synthetic and don't copy anyone, so there are no rights issues. Qwen3-TTS is licensed under Apache 2.0, making commercial use fully permitted.

Currently voice design works best for English, Chinese, Japanese, and Korean — the languages Qwen3-TTS was trained on. More languages will be added as multilingual voice design models become available.

Yes. The studio provides instant preview as you adjust sliders. A short sample sentence is generated (1-2 seconds) so you can quickly iterate. Once satisfied, generate longer text with the designed voice.

Each voice design generation uses standard-tier pricing (2x characters). Live previews use a short fixed sentence to minimize cost. Free accounts start with 15,000 characters.

Each slider maps to a natural language description. For example, the pitch slider at 80% maps to "high-pitched voice." The warmth slider at 90% adds "warm, friendly tone." These descriptions are combined into a single voice profile prompt that Qwen3-TTS uses to generate the voice.
