Whisper Small Hy - Erik Mkrtchyan

This model is a fine-tuned version of openai/whisper-small on the Hy Generated Audio Data with CV 20.0 dataset. It achieves the following results on the evaluation set:

• Loss: 0.1685
• Wer: 36.7015

Model description

This model is based on OpenAI's Whisper Small and fine-tuned for Armenian using exclusively real audio data. It is designed to transcribe Armenian speech into text and serves as a benchmark to evaluate how well the model learns using only real (non-synthetic) data.

Training and evaluation data

The dataset contains both real and high-quality synthetic Armenian speech clips.

Split	# Clips	Duration (hours)
train	9,300	13.53
test	5,818	9.16
eval	5,856	8.76

Total duration: ~31 hours
Train set duration(train+generated): ~13 hours
Test set duration(test+eval) ~18 hours
