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 | 13.43 | 40.87 | 98.0 |
| Common Voice 25 | 1.38 | 5.2 | 96.13 |
| Combined | 11.83 | 35.63 | 80.72 |
~6.8x 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/assamese", torch_dtype=torch.float16).to("cuda").eval()
proc = WhisperProcessor.from_pretrained("BuzzASR/assamese")
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 + Common Voice Corpus 25.0 (Mozilla, March 2025; https://commonvoice.mozilla.org/en/datasets), capped per the paper. Text-only data from the Goldfish corpus (Chang et al., 2026).
Limitations
Monolingual (Assamese only). Evaluated on FLEURS / Common Voice test splits; other domains or dialects may differ.
