We first probe how SOT handles overlapped speech, and we found the decoder performs implicit speaker separation. We hypothesize this implicit separation is often insufficient due to ambiguous acoustic cues in overlapping regions. To address this, SC-SOT explicitly conditions the decoder on speaker information, providing detailed information about \"who spoke when\". Specifically, we enhance the decoder by incorporating: (1) speaker embeddings, which allow the model to focu","authors_text":"Sakriani Sakti, Yuta Hirano","cross_cats":["cs.CL","eess.AS"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2025-06-15T00:37:27Z","title":"SC-SOT: Conditioning the Decoder on Diarized Speaker Information for End-to-End Overlapped Speech Recognition"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2506.12672","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":"sha256:6099c1c965485215dd6bff68310d3385310ee011f5fe3d50b46068256bbb15ef","target":"record","created_at":"2026-07-05T11:21:57Z","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":"72902c90de161925172114e545bde2946b56e3aa1526f23b2f0d4d61cf7e1ada","cross_cats_sorted":["cs.CL","eess.AS"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2025-06-15T00:37:27Z","title_canon_sha256":"aa49c591b788b7729f65ca6d5cad7bc7849766a9911593115b6107a04f474796"},"schema_version":"1.0","source":{"id":"2506.12672","kind":"arxiv","version":1}},"canonical_sha256":"87cbdeedc99e38b8c44e2b640db6445952c860580a724b91e870f754d0ec09f6","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"87cbdeedc99e38b8c44e2b640db6445952c860580a724b91e870f754d0ec09f6","first_computed_at":"2026-07-05T11:21:57.234609Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T11:21:57.234609Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"0iP9cRQ4RV8/mtiP3z3fjSogk6xZK8mxvpabmy0PpOFO+iNsMLBFwjd/zh6lcmW3gJZEN7aErnrMDVNOBceHAw==","signature_status":"signed_v1","signed_at":"2026-07-05T11:21:57.235034Z","signed_message":"canonical_sha256_bytes"},"source_id":"2506.12672","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6099c1c965485215dd6bff68310d3385310ee011f5fe3d50b46068256bbb15ef","sha256:d89a41bb9b1587c85a8ecb7f08e45fdd6b1cddc991106eb009a02ef97652d12f"],"state_sha256":"0bfc82f9ddc5d5a66cc8e52a53f687b6c902c2359d1f4e81a3a78a5e810e5121"}
