# ProSDD-ASV19: 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/ProSDD/codes/tree/bdb80440cd946368e77f4b51f6ddf26c7443dc33) and [paper](https://arxiv.org/abs/2604.13229).

ProSDD (Mahapatra et al., 2026): a fully fine-tuned wav2vec 2.0 XLS-R 300M encoder, first trained (Stage I, bona fide LibriSpeech train-clean-100 + dev only) to predict masked frame-level speaker + prosody targets, then (Stage II) jointly fine-tuned with that objective and a binary real/fake head on ASVspoof 2019 LA train/dev (RawBoost series 3). Inference uses only the clean path: XLS-R CNN front-end + feature projection, latent sequence fixed at 200 frames (zero-padded), 24-layer transformer encoder, mean pool, Linear(1024,512)-ReLU-Linear(512,2). Input as the authors' data_utils_eval.py: 16 kHz, no amplitude normalisation, fixed 4 s (64000 samples) centre crop, shorter clips centre zero-padded. FP32; score = logits[:,1] (bona fide class). Authors' released checkpoint; no upstream license, so the weights are linked from the authors' Google Drive, not re-hosted.

- Weights: **not re-hosted** (the authors grant no license for them). Get the authors' [checkpoint](https://drive.google.com/file/d/1RHY-VELyi4XH-L1egeRcgWjHdkdWV2bO/view); its sha256 is in the `meta.yaml` notes.
- Params: 315.963522 M. Trained on LibriSpeech (stage 1) and ASVspoof 2019 LA train/dev (stage 2); the Arena's 19LA set is eval.
- 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/`.
