about this model
Capabilities
The model handles 30 languages and 22 Chinese dialects, including English accents from multiple regions. It processes speech, singing voice, and songs with background music. A single model supports both offline and streaming inference, as well as long audio transcription.
Performance
Qwen3-ASR-1.7B achieves state-of-the-art results among open-source ASR models and is competitive with the strongest proprietary commercial APIs. The smaller Qwen3-ASR-0.6B offers an accuracy-efficiency trade-off, achieving an average time-to-first-token of 92 ms and transcribing 2,000 seconds of speech in 1 second at a concurrency of 128.
Architecture
Forced Alignment
An optional companion, Qwen3-ForcedAligner-0.6B, predicts timestamps for arbitrary units within up to 5 minutes of speech across 11 languages, outperforming existing end-to-end forced-alignment models in accuracy.
