ASR checkpoints, mirrored for the live-translation app
Streaming Zipformer2 transducers for sherpa-onnx, laid out exactly as the app
expects them: kroko/<language>/{encoder,decoder,joiner}.onnx + tokens.txt.
Nothing here was retrained, re-quantised or otherwise modified — these are the
publishers' bytes, re-hosted so the app controls its own download source.

nemotron/ — the multilingual fallback
NVIDIA Nemotron 3.5 ASR streaming 0.6b, the 1120 ms chunk export, int8,
from https://huggingface.co/nvidia/nemotron-3.5-asr-streaming-0.6b via the
sherpa-onnx export above. Cache-aware FastConformer-RNNT; takes a per-stream
language prompt ("de-DE", "auto", …). Note the prompt table spells Arabic
ar / ar-AR and has no ar-SA.
Both decoders are here. decoder.onnx is the float export the app loads
today, because ONNX Runtime was reported to mis-fuse the int8 decoder's LSTM
slice. decoder.int8.onnx is a quarter of the size and, measured on 47 FLEURS
German clips through sherpa-onnx 1.13.6, transcribes at 11.20 WER against the
float decoder's 11.47 — a paired bootstrap of [-0.09, +0.69], i.e. no
difference. Whether it loads on a given Android runtime still has to be
checked on the device; if it does, it saves 44.8 MB.

Kroko
The three kroko/ checkpoints are Kroko ASR models by Banafo EOOD — https://kroko.ai,
https://huggingface.co/Banafo/Kroko-ASR. Redistributed unmodified.
Turkish comes from the .data community generation, which Banafo
describes as CC BY-SA ("use our CC-BY-SA licensed community models").
Unpacking the container reproduces the four files byte-for-byte; the SHA-256
of every one matches the copy already shipping. Banafo states no CC version
and its LICENSE file is empty, so the version is taken as unspecified.
German and French come from the earlier loose-.onnx generation. Banafo's
model card of 2025-09-25 said of that generation: "the new ones (with .data
extension) are CC-BY-SA licensed, the .onnx are still non-commercial only."
Those files were later removed from Banafo's own repository. Commercial use
of kroko/de and kroko/fr therefore needs written permission from
licensing@banafo.com — this mirror does not grant it and does not imply
Banafo endorses anything here.
No warranty is given or implied. See the upstream repositories for the authoritative terms.
