# Wav2Vec2 Large XLSR Persian ShEMO

This model is a fine-tuned version of [masoudmzb/wav2vec2-xlsr-multilingual-53-fa](https://huggingface.co/masoudmzb/wav2vec2-xlsr-multilingual-53-fa)
on the [ShEMO](https://github.com/pariajm/sharif-emotional-speech-dataset) dataset for speech recognition in Persian (Farsi).
When using this model, make sure that your speech input is sampled at 16 kHz.

It achieves the following results:
- Loss on ShEMO train set: 0.7618
- Loss on ShEMO dev set:   0.6728
- WER on ShEMO train set:          30.47
- WER on ShEMO dev set:            32.85
- WER on Common Voice 13 test set: 19.21
