MiMo-V2.5 ASR
Xiaomi's open-source ASR handles dialects, code-switching, and songs
The Panel's Take
Xiaomi has open-sourced MiMo-V2.5 ASR as part of a full-chain speech stack alongside MiMo-V2.5 TTS. The ASR model is purpose-built for the messy real world: it handles Chinese dialects (Cantonese, Wu, Minnan, Sichuanese), English, code-switching between the two without preset language tags, and — unusually — can transcribe song lyrics even when mixed with music. The model targets agentic scenarios where predictability isn't guaranteed: multi-speaker meetings with overlapping speech, far-field microphone pickups, and high-noise environments. It reaches state-of-the-art or near-SOTA across bilingual recognition, dialect handling, and code-switching benchmarks. The open-source release on Hugging Face and GitHub lets developers fine-tune directly for their language and domain. MiMo-V2.5 ASR fills a gap in the open-source voice ecosystem. Most capable ASR models either require API access (Deepgram, AssemblyAI) or are English-dominant (Whisper). For any developer building for East Asian markets or multilingual audiences, this is a significant free alternative with production-grade accuracy.

“Finally an open-source ASR model that doesn't treat code-switching as an edge case. For developers building multilingual apps in APAC, this is immediately deployable without per-minute API costs eating into margins.”
“Xiaomi's 'state-of-the-art' claims need independent benchmarking — their eval setup favors their training distribution. Hardware requirements for self-hosting at production scale haven't been documented, which is a real deployment blocker.”
“The ability to transcribe code-switched speech is a harbinger of truly global AI applications. When voice AI stops requiring users to pick a language before speaking, the addressable market for voice agents expands by an order of magnitude.”
“Transcribing song lyrics with music in the background is a wildly useful feature for creators producing localization, subtitles, or music content. This opens up karaoke-style captioning and bilingual podcast workflows that were previously painful.”
