# SemTalk Inference Data

Generated SMPL-X predictions from the official SemTalk checkpoints for comparison and visualization without rerunning the full generation pipeline.

## Files

| Archive | Protocol | Description |
| --- | --- | --- |
| `SemTalk_testnpz.zip` | Speaker 2, paper protocol | Generated test `.npz` files |
| `SemTalk_all_speakers_results_npz_25spk.zip` | 25 English BEAT2 speakers | Generated test `.npz` files |

Verify both downloads with `sha256sum -c SHA256SUMS`.

The two releases use different training protocols and should not be interpreted as a controlled single-speaker versus multi-speaker ablation.
