Standard metrics can be applied to evaluate the performance of isolated spoofing detection solutions and others have been proposed to support their evaluation when they are combined with speaker detection. These either have well-known deficiencies or restrict the architectural approach to combine speaker and spoof detectors. In this paper, we propose an architecture-agnostic detection cost function (a-DCF). A generalisation of the original DCF used widely for the assessment of automatic speaker verification (ASV), the a-DCF is designed f","authors_text":"Hye-Jin Shim, Itshak Lapidot, Jean-Francois Bonastre, Jee-weon Jung, Nicholas Evans, Tomi Kinnunen","cross_cats":["cs.LG"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2024-03-03T00:58:27Z","title":"a-DCF: an architecture agnostic metric with application to spoofing-robust speaker verification"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2403.01355","kind":"arxiv","version":2},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:f4d57cc5048ad4126f4c3c004c4093cba7e7928e25def6dfc1c3b20bc2ef1b90","target":"record","created_at":"2026-07-05T10:49:34Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"5e9d15de807db262c9155be74be1585fbe49fc28e75384d39e4f903c201bb631","cross_cats_sorted":["cs.LG"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2024-03-03T00:58:27Z","title_canon_sha256":"07d2039d9a529a6bd3c2dc44a3a7819d2f51c5a61d029fb0351ccf30686fa11a"},"schema_version":"1.0","source":{"id":"2403.01355","kind":"arxiv","version":2}},"canonical_sha256":"6217e6e0612eab7abf62d891c036bf93e0b3021a77221786e7df55d0bd7ae811","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"6217e6e0612eab7abf62d891c036bf93e0b3021a77221786e7df55d0bd7ae811","first_computed_at":"2026-07-05T10:49:34.562259Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T10:49:34.562259Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"kRbbNPPubev6nJeNbN0NY2lP+/yYAhlVqrjdva0UVLXDvbkoInvjraw2w3DjOvmGDKGmupRVut2el3ymlr8SAg==","signature_status":"signed_v1","signed_at":"2026-07-05T10:49:34.562763Z","signed_message":"canonical_sha256_bytes"},"source_id":"2403.01355","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f4d57cc5048ad4126f4c3c004c4093cba7e7928e25def6dfc1c3b20bc2ef1b90","sha256:97ba51b70ef4b39265e816b71a3329d68b213ef4779719babed170875d1a01c9"],"state_sha256":"6d5686ffb8c6de0f2aec5b3ced0f8de9a1a56e8f5b1f603418501f777751fdc3"}
