The smallest of four Qwen3 TTS entries in this catalog. All four share the qwen3_tts loader and all are Apache-2.0. Each repo was checked individually, because size tiers sometimes differ in licence; here they do not. No separate Qwen licence applies.
Summarized from the linked source documents, last checked 25 August 2026. Every claim links to its source; anything unconfirmed is marked unconfirmed.
Apache-2.0. Commercial use is permitted, with no revenue cap and no research-only carve-out. Keep the copyright and licence notices when you redistribute the weights.
Apache-2.0 claims nothing over output. The Qwen3 TTS cards carry no acceptable-use policy and no voice-cloning consent clause. Getting consent for any reference voice you supply is your responsibility; no licence term covers it.
Correction to the shipped catalog: The shipped catalog says "Unknown". It is Apache-2.0, verified on this specific repo and not inferred from the family. The tokenizer is a separate repo (Qwen/Qwen3-TTS-Tokenizer-12Hz), also Apache-2.0.
Based on the licence text as of the date below. Licences change; the links carry the authoritative version.
Transcribed from the shipped catalog, audiocpp_models_catalog.json — that file is authoritative if a number here disagrees with it.
audiocpp-qwen3-tts-0-6b-baseqwen3_ttsThere is no per-model install. One native binary runs all of these, so getting a model is a download of its weights and nothing else — no virtualenv, no torch pin, no CUDA wheel to match against your driver.
soundbox model install audiocpp
soundbox pull audiocpp-qwen3-tts-0-6b-base<models dir>/audiocpp/audiocpp-qwen3-tts-0-6b-base/ rather than in the shared Hugging Face cache, so a download stays scoped to the model you asked for.Primary sources: the model's own repository, the project it came from, and the conversion audio.cpp actually downloads. Never invented — an entry with nothing findable says so instead.
Licence details on these pages are summaries of the linked source documents, last checked 25 August 2026. They are not legal advice, and Soundbox is not affiliated with any model's authors — weights download from Hugging Face under the user's own account and terms. Company and model names identify whose work it is, and belong to their owners. The linked licence text is authoritative; commercial use should be checked against it, per model, before anything ships.
