SpeechAntiSpoofingBenchmarks / AASIST
Model's Last Updated: June 25 2026
Introduction of AASIST
Model Details of AASIST
AASIST
AASIST audio anti-spoofing (voice-deepfake detection) countermeasure from
"AASIST: Audio Anti-Spoofing using Integrated Spectro-Temporal Graph Attention
Networks"
(Jung et al., ICASSP 2022). This is the
official
AASIST
variant
(not AASIST-L), using the upstream
clovaai/aasist
ASVspoof2019 LA pretrained checkpoint. The model takes a raw speech waveform and
returns a score where
higher = more bona fide
.
- Code: https://github.com/clovaai/aasist
- Paper: https://arxiv.org/abs/2110.01200
- Parameters: 297,866 (0.298 M)

Checkpoint:
AASIST.pth
This repo is self-contained for inference: the network definition is in
_net.py
and the exact wrapper used to produce the Arena scores in
aasist.py
.
Architecture
AASIST operates directly on the raw waveform: a sinc-convolution front-end and a RawNet2-style residual encoder produce a spectro-temporal feature map, which is modelled by heterogeneous stacking graph attention layers over spectral and temporal sub-graphs with a learnable max/average readout, followed by a 2-class output (bona fide vs. spoof). The Arena score is the bona-fide logit.
Reproducing the Arena scores
Inference uses a deterministic first-64600-sample window (no random crop),
matching the upstream
data_utils.pad()
used at eval. Audio is provided as
float32 mono at 16 kHz (no resampling in the wrapper).
from aasist import AASIST
m = AASIST(); m.load()
scores = m.score_batch([wav], [16000]) # higher = more bona fide
| Dataset | EER % | n_trials |
|---|---|---|
| ASVspoof2019_LA (in-domain) | 0.83 | 71,237 |
| ASVspoof2021_LA | 12.35 | 181,566 |
| ASVspoof2021_DF | 17.04 | 611,829 |
| InTheWild | 43.01 | 31,779 |
| CD-ADD | 51.05 | 20,786 |
The in-domain ASVspoof2019 LA result reproduces the paper's reported EER (~0.83%).
