# reazonspeech-k2-v2
`reazonspeech-k2-v2` is an automatic speech recognition (ASR) model
trained on [ReazonSpeech v2.0 corpus](https://huggingface.co./datasets/reazon-research/reazonspeech).
This model provides end-to-end Japanese speech recognition based on
[Next-gen Kaldi](https://k2-fsa.org/).
## Model Architecture
* Character-based RNN-T model. The total parameter count is 159.34M.
* This model utilizes an enhanced Transformer architecture called
[Zipformer](https://arxiv.org/abs/2310.11230).
* The training recipe is available on
[k2-fsa/icefall](https://github.com/k2-fsa/icefall/tree/master/egs/reazonspeech/ASR).
## Usage
We recommend to use this model through our
[reazonspeech](https://github.com/reazon-research/reazonspeech)
library.
```
from reazonspeech.k2.asr import load_model, transcribe, audio_from_path
audio = audio_from_path("speech.wav")
model = load_model()
ret = transcribe(model, audio)
print(ret.text)
```
