⬤ Here's the thing—Qwen3-TTS is now officially live on ModelScope, and it's bringing a full open-source voice AI lineup to developers everywhere. The Qwen team released the complete Qwen3-TTS family, including VoiceDesign, CustomVoice, and Base variants, with all model weights, code, and the research paper included. The system architecture and benchmark data show what these models can actually do.
⬤ The family packs five models ranging from 0.6B to 1.8B parameters, with support for 10 languages and dialects. These models handle voice cloning, multilingual speech synthesis, and cross-lingual generation—basically everything you'd need for serious voice AI work. The flexibility across different model sizes means developers can pick what fits their use case, whether that's lightweight deployment or maximum quality.
⬤ Benchmark results show performance across voice cloning accuracy, multilingual similarity, and cross-lingual evaluations—lower error rates mean better results compared to competing models. The data proves these aren't just theoretical improvements; they're measurable gains in real-world voice synthesis tasks.
⬤ The Qwen3-TTS 12Hz tokenizer is where things get interesting. It's built to deliver higher compression efficiency without sacrificing speech quality. Tokenizer benchmarks include metrics like PESQ, STOI, UTMOS, and similarity scores—higher numbers mean better performance. The data shows Qwen's tokenizer holds its own against alternative approaches when it comes to speech reconstruction and intelligibility.
⬤ This release matters because open-source TTS systems are becoming critical infrastructure for media production, accessibility tools, and AI app development. By releasing full weights and training support, Qwen3-TTS is democratizing access to advanced voice synthesis tech while pushing competition in the voice AI space. The combo of multilingual coverage, customizable voice design, and efficient tokenization shows where speech tech is headed—more capable, more transparent, more accessible.
