Qwen3-TTS 1.7B
Qwen3-TTS 1.7B costs $0.0060/req on FairStack — a text to speech model for Custom voice creation, Voice design experimentation, Default TTS generation. No subscription required. Pay per generation with full REST API access. FairStack applies a transparent 20% margin on infrastructure cost so you always see the real price.
What is Qwen3-TTS 1.7B?
Qwen3-TTS is FairStack's default text-to-speech model, offering a unique dual capability: voice design from text descriptions and voice cloning from reference audio. In voice design mode, users describe the desired voice characteristics in natural language, and the model generates matching speech without any reference audio needed. The voice design capability is particularly distinctive. Rather than choosing from a preset library, users can describe a voice as they imagine it, and the model creates speech matching that description. Clone mode requires both reference audio and a reference text transcript for best results. Self-hosting provides cost advantages and privacy. Compared to IndexTTS2 which offers higher cloning fidelity, Qwen3-TTS's voice design mode provides a capability no other model on the platform offers. Against preset-based models like Kokoro with 54 fixed voices, voice design offers unlimited vocal variety. As the default TTS model, it is well-tested across diverse use cases. Best suited for custom voice creation, voice design experimentation, and general TTS generation where the flexibility to either design a voice from description or clone from audio provides maximum creative control. Available on FairStack at infrastructure cost plus a 20% platform fee.
