weemed/Breeze-ASR-26-ONNX

Breeze-ASR-26 — ONNX (sherpa-onnx, INT8)

The only build that runs on Android, iOS, and in the browser (WASM). Encoder and decoder are single ONNX files each. Slower on CPU (RTF 1.3) than CT2/GGML — use this only where you need mobile or WASM; otherwise prefer CT2 (speed) or GGML (low RAM).

Part of the Breeze-ASR-26 edge family — the same MediaTek model in every runtime, pick by your constraint:

Repo	Runtime	RSS	RTF (CPU 4-thread)	Best for
Breeze-ASR-26-ct2	CTranslate2 / faster-whisper	~2.9 GB	0.21	servers, 8 GB+ hosts, GPU
Breeze-ASR-26-GGML	whisper.cpp / MacWhisper	1.85 GB	0.40	4 GB hosts, desktop apps
Breeze-ASR-26-ONNX	sherpa-onnx / onnxruntime	—	1.3	Android / iOS / WASM

All Apache-2.0, derived from MediaTek-Research/Breeze-ASR-26. Measured on real multi-speaker Mandarin meeting audio. Mandarin does not regress; Taigi is transcribed as Mandarin meaning (not verbatim Taigi characters).
