SAVRN's Notes on Qwen3-TTS-12Hz-1.7B-CustomVoice
The same 1.9B-parameter body and 4.6 GB 16-bit footprint as the Base on this list — the difference is the job. CustomVoice clones a speaker from a short reference clip, making it the variant for assistant and dubbing products, and it draws 2.4M downloads a month against the Base's 3.7M. One MI300X at $1.85 an hour is again far more card than the 4.5 GB of weights need.
Apache 2.0 permits commercial use; the obligation that matters is not in the license. Voice cloning needs a consent workflow — recording notice, revocation, speaker verification — before it touches users, and that process is yours to build. The library field is empty on both TTS listings here, so prove your serving stack loads Qwen3TTSForConditionalGeneration first. The card describes ten languages including Chinese, English, Japanese, Korean and the main European languages.
SAVRN's Notes on Qwen3-TTS-12Hz-1.7B-VoiceDesign
The VoiceDesign version of Qwen3-TTS creates a new voice from a written description, such as a warm, calm mid-forties narrator, rather than cloning a real person. That avoids the consent questions cloning raises, which makes it a practical choice for brand voices.
It has 1.9B parameters and needs under 5 GB at 16-bit. Apache 2.0 allows commercial use. Design a voice once, then use the CustomVoice model to keep it consistent across content.
