# `rinna/japanese-hubert-base`

![rinna-icon](./rinna.png)

# Overview

This is a Japanese HuBERT Base model trained by [rinna Co., Ltd.](https://rinna.co.jp/)

* **Model summary**

  The model architecture is the same as the [original HuBERT Base model](https://huggingface.co/facebook/hubert-base-ls960), which contains 12 transformer layers with 12 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-base"
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, 768]
```
