# `rinna/japanese-hubert-large`
# Overview
This is a Japanese HuBERT Large model trained by [rinna Co., Ltd.](https://rinna.co.jp/)
* **Model summary**
The model architecture is the same as the [original HuBERT Large model](https://huggingface.co/facebook/hubert-large-ll60k), which contains 24 transformer layers with 16 attention heads.
The model was trained using code from the [official repository](https://github.com/facebookresearch/fairseq/tree/main/examples/hubert), and the detailed training configuration can be found in the same repository and the [original paper](https://ieeexplore.ieee.org/document/9585401).
* **Training**
The model was trained on approximately 19,000 hours of following Japanese speech corpus ReazonSpeech v1.

# How to use the model
```python
import soundfile as sf
from transformers import AutoFeatureExtractor, AutoModel
model_name = "rinna/japanese-hubert-large"
feature_extractor = AutoFeatureExtractor.from_pretrained(model_name)
model = AutoModel.from_pretrained(model_name)
model.eval()
raw_speech_16kHz, sr = sf.read(audio_file)
inputs = feature_extractor(
raw_speech_16kHz,
return_tensors="pt",
sampling_rate=sr,
)
outputs = model(**inputs)
print(f"Input: {inputs.input_values.size()}") # [1, #samples]
print(f"Output: {outputs.last_hidden_state.size()}") # [1, #frames, 1024]
```
A fairseq checkpoint file can also be available [here](https://huggingface.co/rinna/japanese-hubert-large/tree/main/fairseq).
