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.

Voicebox is an open-source desktop voice synthesis studio that runs entirely on your local machine — no subscriptions, no API keys, no data leaving your device. It bundles five TTS engines (Qwen3-TTS, LuxTTS, and Chatterbox variants) covering 23 languages, giving you ElevenLabs-grade capabilities at zero recurring cost. The standout features are voice cloning from audio samples in seconds, a multi-track Stories Editor for composing podcasts and dialogue scenes, eight post-processing audio effects (pitch shift, reverb, delay, compression), and smart auto-chunking that handles up to 50,000 characters with crossfaded seams. Built-in Whisper transcription rounds out the workflow. A full REST API means you can wire Voicebox into any downstream pipeline or custom integration. Technically it's a Tauri desktop shell (Rust) wrapping a React frontend and Python FastAPI backend. GPU acceleration supports Apple Silicon via MLX, NVIDIA via CUDA, AMD via ROCm, and Windows via DirectML. The MIT license and local-first architecture make it especially compelling for any use case where sending voice data to the cloud is a concern.
Reviewer scorecard
“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.”
“Five TTS engines under one roof, a full REST API, and Tauri + Python FastAPI architecture that's easy to extend. The auto-chunking to 50k characters and crossfading solve the real pain of long-form voice generation. This is the local voice stack I've been waiting for.”
“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.”
“Running five different TTS engines locally means significant disk and RAM footprints. Quality will still trail ElevenLabs' latest models for professional use cases. The stories editor sounds great in theory but multi-track voice timelines are notoriously fiddly — wait for v1.0 stability.”
“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.”
“Voicebox signals the commoditization of ElevenLabs-quality voice synthesis. When creators can clone voices, build multi-character audio dramas, and deploy via REST API for zero per-character cost, the economics of audio content production change fundamentally. This is that inflection point.”
“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.”
“The Stories Editor alone is worth it — composing multi-voice podcast conversations in a timeline without a cloud subscription is a dream. Voice cloning from samples, eight audio effects, and 23-language support make this my new go-to for any audio content work. It ships today.”
