HQ-MPSD Dataset v1 The structure of dataset folder is below: HQ-MPSD/├── English/│ ├── Bonafide/│ │ ├──<speakerID>_<audiobookId>_<segmentID>.flac│ │ └── ...│ ├── Fully_Fake/│ │ ├── <speakerID>_<audiobookId>_<segmentID>_f.flac│ │ └── ...│ ├── Partial_Fake_Clean/│ │ ├── <speakerID>_<audiobookId>_<segmentID>_p.flac│ │ └── ...│ └── ...│ ├── Partial_Fake_Noisy/│ │ ├── <speakerID>_<audiobookId>_<segmentID>_pn.flac│ │ └── ...│ └── Frame_level_label.txt│ └── Noise_augmentation_info.txt├── French/│ └── (same structure as English)├── German/│ └── (same structure as English)└── ... Frame labels are defined as: 0 → Bonafide frame 1 → Deepfake frame 2 → Transition frame Each row in the Frame_level_label.txt is formatted as follows: <id> <label_for_each_30ms_frame> This file provides detailed provenance for noise-augmented audio samples, including: the augmentation type or noise category the specific noise file from OpenSLR26 the specific noise file from MUSAN Each row in the Noise_augmentation_info.txt is formatted as follows: <id> <augmentation_label> <used_file_path_in_OpneSLR26> <<used_file_path_in_MUSAN>
