Word Error Rate almost 100% after first epoch

Hello! I’ve attempted to train an ASR system using Speechbrain. However, after the first epoch, my word error rate is insane - it is 99.63%. Literally almost 100%. Here’s the whole line from the training log:

epoch: 1, lr: 1.00e+00 - train loss: 5.15 - valid loss: 4.42, valid CER 81.95, valid WER. 99.63

I’m not sure if I’ve just completely screwed things up. Please let me know if I have!

Thank you!

This seems to happen occasionally when training the ASR model, especially when training multilingual content.
