# GigaAM-v2-CTC 🤗 Hugging Face transformers

* original git https://github.com/salute-developers/GigaAM

Russian ASR model GigaAM-v2-CTC.

## Model info
This is an original GigaAM-v2-CTC with `transformers` library interface.

File [`gigaam_transformers.py`](https://huggingface.co/waveletdeboshir/gigaam-ctc/blob/main/gigaam_transformers.py) contains model, feature extractor and tokenizer classes with usual transformers methods. Model can be initialized with transformers auto classes (see an example below).

## Installation

my lib versions:
* `torch` 2.5.1
* `torchaudio` 2.5.1
* `transformers` 4.49.0

## Usage
Usage is same as other `transformers` ASR models.

```python
from transformers import AutoModel, AutoProcessor
import torch
import torchaudio

# load audio
wav, sr = torchaudio.load("audio.wav")
# resample if necessary
wav = torchaudio.functional.resample(wav, sr, 16000)

# load model and processor
processor = AutoProcessor.from_pretrained("waveletdeboshir/gigaam-ctc", trust_remote_code=True)
model = AutoModel.from_pretrained("waveletdeboshir/gigaam-ctc", trust_remote_code=True)
model.eval()

input_features = processor(wav[0], sampling_rate=16000, return_tensors="pt")

# predict
with torch.no_grad():
    logits = model(**input_features).logits
# greedy decoding
greedy_ids = logits.argmax(dim=-1)
# decode token ids to text
transcription = processor.batch_decode(greedy_ids)[0]

```
