Whisper Small - Greek (el)

This model is a fine-tuned version of openai/whisper-small on the mozilla-foundation/common_voice_11_0 el dataset for translation from Greek to English. It achieves the following results on the evaluation set:

Loss: 0.4642
Wer: 25.6965

Model description

This model was finetuned with the encoder frozen. Only the decoder weights have been changed by this training run.

Intended uses & limitations

The purpose of this model was to understand how the freezing of a part of the model might affect learning, in an effort to assess the feasibility of enabling adapters.

Training and evaluation data

The training was performed by streaming interleaved train+eval spits of the greek (el) subset of mozilla-foundation/common_voice_11_0 (el). The test set was similarly used for validation.

Training procedure

Fine-tuning was performed on a lambdalabs laptop equipped with an NVIDIA GeForce RTX 3080 Laptop GPU (16GB).

The script used to perform the training run_speech_recognition_seq2seq_streaming.py is included in the files of this space with the following arguments:
