This model is a fine-tuned version of openai/whisper-large-v3-turbo.
It is adapted for Slovak ASR using SloPalSpeech: 2,806 hours of aligned, ≤30 s speech–text pairs from official plenary sessions of the Slovak National Council.

Language: Slovak
Domain: Parliamentary / formal speech
Training data: 2,806 h
Intended use: Slovak speech recognition; strongest in formal/public-speaking contexts

🧪 Evaluation

Dataset	Base WER	Fine-tuned WER	Δ (abs)
Common Voice 21 (sk)	31.7	13.2	-18.5
FLEURS (sk)	10.7	6.4	-4.3

Numbers from the paper’s final benchmark runs.

🔧 Training Details

Framework: Hugging Face Transformers
Hardware: NVIDIA A10 GPUs
Epochs: up to 3 with early stopping on validation WER
Learning rate: ~40× smaller than Whisper pretraining LR

⚠️ Limitations

Domain bias toward parliamentary speech (e.g., political vocabulary, formal register).
As with Whisper models generally, occasional hallucinations may appear; consider temperature fallback / compression-ratio checks at inference time.
Multilingual performance is not guaranteed (full-parameter finetuning emphasized Slovak).
