Japanese speech recognition model listen-windy-lingua-ja-ct2

Open speech-to-text model published by Windstorm Labs on Hugging Face.

Task: Speech-to-text (automatic speech recognition)
Language: Japanese
Lineage: Whisper community fine-tune (upstream undocumented)
Formats in the repo: ct2-int8
Hugging Face: WindyWord/listen-windy-lingua-ja-ct2
Last updated on HF: 2026-08-05

Quality

Not benchmarked by this site yet. Speech models have no published word-error rates here; any figures in the Hugging Face card were not re-measured by us.

From the model card: Quality note: based on whisper-base-japanese (74M params). Small model for a top-10 language; production users may prefer the multilingual `openai/whisper-large-v3` for higher accuracy.

How to run

Shell

pip install faster-whisper soundfile

Python

import soundfile as sf
from huggingface_hub import snapshot_download
from faster_whisper import WhisperModel

path = snapshot_download("WindyWord/listen-windy-lingua-ja-ct2", allow_patterns=["ct2-int8/*"])
model = WhisperModel(f"{path}/ct2-int8", device="cpu", compute_type="int8")
audio, sr = sf.read("audio.wav", dtype="float32")   # 16 kHz mono
segments, info = model.transcribe(audio)
print("".join(s.text for s in segments))

Tested: Pattern run on 2026-10-01 against the ct2-int8 build of WindyWord/listen-windy-nano with faster-whisper 1.2.1 on CPU. Not run on every model individually.
