DeCRED-base

This is a 39M encoder-decoder Ebranchformer model trained 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 class to transcribe audio files of arbitrary length.

# 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
