Overview

This is a Japanese HuBERT Base model trained by rinna Co., Ltd.


How to use the model

import soundfile as sf
from transformers import AutoFeatureExtractor, AutoModel

model_name = "yky-h/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]

A fairseq checkpoint file can also be available here.

Using it via the API

Call it like any OpenAI endpoint

Once AxForge deploys japanese-hubert for you, it answers on the OpenAI-compatible API — the same base URL and keys as every other model. (japanese-hubert below is illustrative; you get the exact model name on deployment.)

$ curl -sS https://api.axforge.ai/v1/embeddings \
  -H "Authorization: Bearer $AXFORGE_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"model":"japanese-hubert","input":"text to embed"}'
