The proposed approach employs an Arrival-Order Speaker Cache (AOSC) to store frame-level acoustic embeddings of previously observed speakers. Unlike conventional speaker-tracing buffers, AOSC orders embeddings by speaker index corresponding to their arrival time order, and is dynamically updated by selecting frames with the highest scores based on the model's past predictions. Notably, the number of stored embeddings per speaker is dete","authors_text":"Boris Ginsburg, He Huang, Ivan Medennikov, Jagadeesh Balam, Jinhan Wang, Kunal Dhawan, Taejin Park, Weiqing Wang","cross_cats":["cs.SD"],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2025-07-24T14:30:48Z","title":"Streaming Sortformer: Speaker Cache-Based Online Speaker Diarization with Arrival-Time Ordering"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2507.18446","kind":"arxiv","version":1},"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":"sha256:52b9b2f18dea74d7a174f802dc67a44762cc9fd2fee76e223d04b21ff3e8f82a","target":"record","created_at":"2026-07-05T11:42:48Z","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":"2dae014aa6f61a47db4f7f2a25f16c403e0fbf664f240a922e92ff92c9e4f2db","cross_cats_sorted":["cs.SD"],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2025-07-24T14:30:48Z","title_canon_sha256":"7490c9bb361f25ac6055ef6e8bf03cbd22930251c0289146a2ff37cf6257371d"},"schema_version":"1.0","source":{"id":"2507.18446","kind":"arxiv","version":1}},"canonical_sha256":"129b4e0ad536fa9a98f543c47d67cf2dba18b2f97850be95579df61ab86b2daa","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"129b4e0ad536fa9a98f543c47d67cf2dba18b2f97850be95579df61ab86b2daa","first_computed_at":"2026-07-05T11:42:48.127291Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:42:48.127291Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"xIvCjdiTQYyJg9T3N2Lx9jCo2SYH7jpNivWLaO9kPIa+JvUxjSyEPau7BNzcszg3PvHXavbJb9AhexXIocwCBw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:42:48.127726Z","signed_message":"canonical_sha256_bytes"},"source_id":"2507.18446","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:52b9b2f18dea74d7a174f802dc67a44762cc9fd2fee76e223d04b21ff3e8f82a","sha256:30351c98bcf00e5061d101c0f9d02e45be14b4c5c4fcecffb8507a99afe5fd5e"],"state_sha256":"2c318f7dffc973c255ac5a8f7908e8e68492d544dbac0bbaaae673c23931767b"}
