# SSL-Mamba: Speech Anti-Spoofing Arena wrapper
Packaged for the [Speech Anti-Spoofing Arena](https://huggingface.co/spaces/SpeechAntiSpoofingBenchmarks/SpeechAntiSpoofingArena) from the authors' [code](https://github.com/hoanmyTran/spoofing_ssl_mamba) and [paper](https://www.isca-archive.org/interspeech_2025/tran25b_interspeech.html).
SSL-Mamba (Tran et al., Interspeech 2025): a fully fine-tuned wav2vec 2.0 XLS-R 300M front-end whose 25 hidden states are each projected to 128-d (Linear + SiLU) and summed (self-gated layer aggregation), a multi-kernel gated convolution (MultiConv cgMLP, kernels 7/15/23/31) fusion module, 12 unidirectional Mamba (v1 selective SSM) residual blocks with LayerNorm, multi-head attention pooling (4 heads, mean + std) and a 2-way head. Official authors' checkpoint (interspeech2025.pt), trained on ASVspoof2019 LA train. Not to be confused with XLSR-Mamba (Xiao & Das), a different model.
- Checkpoint (commit-pinned): [model.safetensors](https://huggingface.co/SpeechAntiSpoofingBenchmarks/SSL-Mamba/blob/3565084c8f0125b48ca79525674a05167638e40a/model.safetensors)
- Params: 317.5213 M. Trained on ASVspoof 2019 LA train.
- Score: higher = bona fide. J-SPAW_LA was scored with the PyTorch wrapper; the other datasets with the
TensorRT drop-in class (FP32 on the RTX 4070 Ti SUPER; FP32 on the RTX 5060 Ti), which matched PyTorch on the full J-SPAW_LA set.

EER% (lower is better); EmoSpoofTTS and LRLspoof are spoof-only and use 1-SRR% at the model's
DeepVoice EER threshold. Per-dataset scores are under `.eval_results/`.
