DF Arena 1B - Antispoofing Model
We are excited to release DF Arena 1B Universal Antispoofing model 🔥trained on traditional speech antispoofing datasets in addition to singing and environmental deepfake data. Check out the release on DF Arena leaderboard
Training Data
- ASVspoof 2019, 2024
- Codecfake
- LibriSeVoc
- DFADD
- CTRSVDD
- SpoofCeleb
- MLAAD
- EnvSDD
Usage
from transformers import pipeline
import librosa
#load model
pipe = pipeline("antispoofing", model="Speech-Arena-2025/DF_Arena_1B_V_1", trust_remote_code=True, device='cuda')
audio, sr = librosa.load("sample.wav", sr=16000)
result = pipe(audio)
print(result)
# Output:
{'label': 'spoof', 'logits': [[1.5515458583831787, -1.2254822254180908]], 'score': 0.9414217472076416, 'all_scores': {'spoof': 0.9414217472076416, 'bonafide': 0.05857823044061661}}
