# DeCRED-base
This is a  **40M encoder-decoder Ebranchformer model** trained with an decoder-centric regularization technique on 6,000 hours of open-source normalised English data. 

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/DeCRED-small"
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"

# Run beam search decoding with joint CTC-attention scorer
result_beam = pipe("audio.wav")

# Run greedy decoding without joint CTC-attention scorer
pipe.model.generation_config.ctc_weight = 0.0
pipe.model.generation_config.num_beams = 1

result_greedy = pipe("audio.wav")

```
