Our Take

Xiaomi just dropped an 8B open-source speech model that actually competes with Whisper on accuracy. MiMo-2.5-ASR handles eight Chinese dialects, code-switched Chinese-English speech, AND song lyrics — no language-tagging post-processing required. The numbers back it up: 5.73% WER on English versus Whisper's 7.44%, 19.55% on Wu dialect versus FunASR's 29.08%, and 3.95% on lyrics. MIT licensed, free, self-hostable — and it addresses what the benchmark babies won't tell you: most ASR models look amazing on clean studio data and then quietly fail in production where audio is noisy, speakers overlap, and people switch languages mid-sentence. This is the move for voice product teams building bilingual or Chinese-language pipelines who need accuracy that actually holds up outside the lab.

An 8B open-source speech recognition model from Xiaomi that transcribes Mandarin, English, eight Chinese dialects, code-switched speech, and song lyrics. Built for ML engineers, researchers, and developers building real-world voice applications.

Problem It Solves
Most ASR models are benchmarked on clean studio data but deployed into the real world where audio is noisy, speakers overlap, and people switch languages mid-sentence. The gap between benchmark accuracy and production accuracy is where voice products quietly fail.
Target Customer
ML engineers and voice product teams building bilingual or Chinese-language transcription pipelines who need accuracy that holds up outside the lab.
Use Cases
Location-based audio guides with multilingual support, Travel apps requiring dialect understanding, Bilingual transcription pipelines, Chinese-language voice products

Differentiator
On Open ASR Leaderboard: 5.73% average WER on English (vs Whisper large-v3 at 7.44%), 19.55% on Wu dialect (vs FunASR-1.5 at 29.08%), 3.95% on lyrics (vs Gemini 2.5 Pro at 4.25%)
Why Now
Open-source ASR has been catching up to closed models for years. MiMo-2.5-ASR demonstrates the gap is now very small, and in some scenarios gone.
