Whisper Small Hy 2 - Erik Mkrtchyan

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

• Loss: 0.0999
• Wer: 22.7854

Model description

This model is based on OpenAI's Whisper Small and fine-tuned for Armenian using a combination of real and synthetic audio data. It is designed to transcribe Armenian speech into text.

Intended uses & limitations

Intended Uses:

• Armenian speech-to-text applications
• Research on ASR for low-resource languages
• Educational and experimental projects involving Whisper models

Limitations:

• May not generalize well to accents or noisy audio not represented in the training set
• he model may hallucinate text or produce inaccurate transcriptions, especially on unusual or out-of-distribution inputs, due to the inclusion of TTS-generated synthetic data in training.

Training and evaluation data

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

Total duration: ~318 hours
Train set duration(train+generated#1+generated#2: ~300 hours
Test set duration(test+eval) ~18 hours
