stt_is_quartznet15x5_ft_ep56_875h

NOTE! This model was trained with the NeMo version: nemo-toolkit==1.10.0

The "stt_is_quartznet15x5_ft_ep56_875h" is an acoustic model created with NeMo which is suitable for Automatic Speech Recognition in Icelandic.

It is the result of fine-tuning the model "QuartzNet15x5Base-En.nemo" with around 875 hours of Icelandic data developed by the Language and Voice Laboratory. Most of the data is available at public repositories such as LDC or OpenSLR

The specific list of corpora used to fine-tune the model is:

The fine-tuning process was performed during September (2022) in the servers of the Language and Voice Laboratory (https://lvl.ru.is/) at Reykjavík University (Iceland) by Carlos Daniel Hernández Mena.
