hayamimi Review 2026 — Real-Time Multilingual Speech-to-Text on CPU Only, No Cloud, Under 2GB RAM

hayamimi (早耳) is a real-time, multilingual speech-to-text pipeline that runs on CPU only — live subtitles, a browser dashboard, speaker labels, and on-the-fly translation, with no GPU, no cloud API, and under 2GB RAM. Instead of one general-purpose Whisper model, it routes each utterance to a language-specialist model via sherpa-onnx, cutting Japanese broadcast CER from 13.8% (whisper-large-v3-turbo) to 5.8% while running 10-50x realtime on a 6-core desktop CPU.
