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 class to transcribe audio files of arbitrary length.

# The warning can be ignored.
