Results (normalized CER / WER, %)
Table with columns: Test set, CER, WER, Whisper-large-v3 (zero-shot) CER| Test set | CER | WER | Whisper-large-v3 (zero-shot) CER |
|---|
| FLEURS | 3.35 | 10.6 | 5.11 |
| Combined | 3.09 | 11.67 | 5.11 |
~1.7x CER reduction over Whisper zero-shot on the combined test set.
Usage
import torch, torchaudio
from transformers import WhisperForConditionalGeneration, WhisperProcessor
model = WhisperForConditionalGeneration.from_pretrained("BuzzASR/croatian", torch_dtype=torch.float16).to("cuda").eval()
proc = WhisperProcessor.from_pretrained("BuzzASR/croatian")
wav, sr = torchaudio.load("audio.wav")
feats = proc(wav[0], sampling_rate=16000, return_tensors="pt").input_features.to("cuda").half()
ids = model.generate(feats, num_beams=1, no_repeat_ngram_size=3, repetition_penalty=1.2)
print(proc.batch_decode(ids, skip_special_tokens=True)[0])
The language/task prompt is baked into the generation config, so no language= argument is needed.
Training data
FLEURS, capped per the paper. Text-only data from the Goldfish corpus (Chang et al., 2026).
Limitations
Monolingual (Croatian only). Evaluated on FLEURS / Common Voice test splits; other domains or dialects may differ.
