To address this issue, we introduce MultiAPI Spoof, a multi-API audio anti-spoofing dataset comprising about 230 hours of synthetic speech generated by 30 distinct APIs, including commercial services, open-source models, and online platforms. Furthermore, we propose Nes2Net-LA, a local-attention enhanced variant of Nes2Net that improves local context modeling and fine-grained spoofing feature ext","authors_text":"Linxi Li, Liwei Jin, Ming Li, Xueping Zhang, Yechen Wang, Zhenshan Zhang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SD","submitted_at":"2025-12-08T09:43:30Z","title":"MultiAPI Spoof: A Multi-API Dataset and Local-Attention Network for Speech Anti-spoofing Detection"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2512.07352","kind":"arxiv","version":4},"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:b3f96544f240b669c1ee9517671ab87dc0b2270ae73b91ce3117e9fe04c3fec8","target":"record","created_at":"2026-06-09T02:07:14Z","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":"c099ba6c3ae620e4d7c7b30860c86ecfd58540accbd24c8a35197b5e24561eea","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SD","submitted_at":"2025-12-08T09:43:30Z","title_canon_sha256":"ada88553e1ddbd81b299b1fe275cf3eaffc9e093058a798aebe95f2b5c76e319"},"schema_version":"1.0","source":{"id":"2512.07352","kind":"arxiv","version":4}},"canonical_sha256":"3f8a66fd0d7db153ac4c5e06ef6400f47093d1ef117ed164cdb0b9e3a8e914ec","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"3f8a66fd0d7db153ac4c5e06ef6400f47093d1ef117ed164cdb0b9e3a8e914ec","first_computed_at":"2026-06-09T02:07:14.779846Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-09T02:07:14.779846Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"GmRExnp6VQL4Sjvhwhl0P7cYrWcHewkU86qnw2uMnKFSRyJvrmdzptpbnc6agJbfUbps/8Z7ma2+vMkw6AXEBw==","signature_status":"signed_v1","signed_at":"2026-06-09T02:07:14.780397Z","signed_message":"canonical_sha256_bytes"},"source_id":"2512.07352","source_kind":"arxiv","source_version":4}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:b3f96544f240b669c1ee9517671ab87dc0b2270ae73b91ce3117e9fe04c3fec8","sha256:12d842a841865c599d53c8cfe7c471eb79485b951c59dca1ed8faddecd127f67"],"state_sha256":"3b46289f3a730b3e6fee6596d94d71f85c779c90ac893d0f3007d321bf92a007"}
