# EBranchRegulaFormer
This is a  **174M encoder-decoder Ebranchformer model** trained with an intermediate regularization technique on 6,000 hours of open-source English data. 
It achieves Word Error Rates (WERs) comparable to `openai/whisper-medium.en` across multiple datasets with just 1/4 of the parameters. 

Architecture details, training hyperparameters, and a description of the proposed technique will be added soon.

*Disclaimer: The model currently hallucinates on segments containing silence only, as it was previously not trained on such data. The fix will be added soon.*

The model can be used with the [`pipeline`](https://huggingface.co/docs/transformers/main_classes/pipelines#transformers.AutomaticSpeechRecognitionPipeline)
class to transcribe audio files of arbitrary length.

```python
from transformers import pipeline

model_id = "BUT-FIT/EBranchRegulaFormer-medium"
pipe = pipeline("automatic-speech-recognition", model=model_id, feature_extractor=model_id, trust_remote_code=True)
# In newer versions of transformers (>4.31.0), there is a bug in the pipeline inference type.
# The warning can be ignored.
pipe.type = "seq2seq"

# Standard greedy decoding
result = pipe("audio.wav")

# Beam search decoding with joint CTC-autoregressive scorer
generation_config = pipe.model.generation_config
generation_config.ctc_weight = 0.3
generation_config.num_beams = 5
generation_config.ctc_margin = 0
result = pipe("audio.wav")
```
