Qwen3-TTS: on-device text-to-speech voiceover for Korean and English. Type text, get a spoken audio file back — with a picked narrator voice preset. Runs locally in the studio.

What it does
Qwen3-TTS turns written text into spoken audio. Give it a sentence, paragraph, or script in Korean or English, choose a narrator voice preset, and it produces a voiceover audio clip. Unlike commercial TTS services (ElevenLabs, Google Cloud TTS, OpenAI TTS), this node runs entirely on-device — the audio never leaves your machine, and you don't need an API key or subscription. Qwen3-TTS is developed by Alibaba's Qwen team as part of their broader Qwen3 speech stack (which also includes Qwen3-ASR for speech recognition). The upstream model supports voice design, voice cloning, and voice presets; the studio exposes the preset flow (pick a named voice) as the first option, keeping the workflow simple.
Problem it solves
- On-device voiceover – Generate spoken audio without sending text to a third-party API — good for privacy-sensitive scripts, offline workflows, or when you don't want to manage API keys and quotas
- Korean + English support – Bilingual out of the box, so you can voice both language markets from one node
- Auto language handling – By default the model detects the language from the text; you can override to force Korean or English if the model gets it wrong on mixed-language input
- Narrator voice presets – Pick a named voice preset and get a consistent narrator persona across generations
- Free – No per-minute API cost, no monthly subscription, no rate limits — just local compute
- Script narration – Turn long-form written content (blog posts, product descriptions, video scripts) into voiceovers
- Video / animation dubbing – Generate narration tracks for videos or animations without a voice actor
- Accessibility – Convert written content into audio for users who prefer to listen
Input/Output
- Input: Text to speak
- Plain text in Korean or English (or a mix — the model can handle bilingual text)
- Options:
- Narrator voice preset (default: default)
- Select a named voice preset (a specific narrator identity — timbre, pitch, and speaking style)
- The upstream Qwen3-TTS model also supports voice design and voice cloning; the studio node currently exposes the preset flow
- Advanced Options:
- Spoken language hint (Auto / Korean / English, default Auto)
- Auto — model detects the language from the input text itself (recommended, especially for mixed text)
- Korean — force Korean pronunciation and prosody
- English — force English pronunciation and prosody
- Output: An audio file containing the spoken voiceover of the input text, in the selected voice
Accuracy & Speed

|
| Type |
Local (on-device) model — no external API dependency |
| Provider |
Alibaba Qwen — part of the Qwen3 speech stack (siblings: Qwen3-ASR, Qwen3-ForcedAligner) |
| Languages |
Korean and English (UI-exposed); the upstream model may support additional languages |
| API key required? |
No — runs locally in the studio |
| Internet required? |
No — audio generation happens on-device |
| Voice control |
Preset selection in the studio (upstream model supports voice design and voice cloning as well) |
| Compare to external TTS |
No per-minute cost or API quota; audio stays on-device (privacy); trade-off is local compute usage vs. offloading to a cloud API |
