Various clues have been investigated such as pre-recorded enrollment utterances, direction information, or video of the target speaker. In this paper, we explore the use of speaker activity information as an auxiliary clue for single-channel neural network-based speech extraction. We propose a speaker activity driven speech extraction neural network (ADEnet) and show that it can achieve performance levels competitive with enrollment-based","authors_text":"Katerina Zmolikova, Keisuke Kinoshita, Marc Delcroix, Tomohiro Nakatani, Tsubasa Ochiai","cross_cats":["cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2021-01-14T09:21:51Z","title":"Speaker activity driven neural speech extraction"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2101.05516","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:a1a774c95aa3db98f3954f7077cf42df3b428542e089e5003a9c724c14193d85","target":"record","created_at":"2026-07-05T02:14:13Z","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":"c665fdbf2100d8a4f5eb57f445c3bccb5344a301ee19c3727fe06132ab951bd2","cross_cats_sorted":["cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2021-01-14T09:21:51Z","title_canon_sha256":"0f261786fbc739d2230f60713d6a5bd336d27cfb400446648b13b0428b341464"},"schema_version":"1.0","source":{"id":"2101.05516","kind":"arxiv","version":2}},"canonical_sha256":"ac7b48a258d76e84e506049a74643de91af25c6f9c566da5ccabfbf57fd4942f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"ac7b48a258d76e84e506049a74643de91af25c6f9c566da5ccabfbf57fd4942f","first_computed_at":"2026-07-05T02:14:13.713682Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T02:14:13.713682Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Bc93EIKx4IZ2S7a6AIRx3o57j7fiSEHpv2NZieVMwZ44J7qgab+4mbvXNYLLd04Lx3Jk7GSwvOkqSoQ/s3TWDQ==","signature_status":"signed_v1","signed_at":"2026-07-05T02:14:13.714092Z","signed_message":"canonical_sha256_bytes"},"source_id":"2101.05516","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:a1a774c95aa3db98f3954f7077cf42df3b428542e089e5003a9c724c14193d85","sha256:8612c29e5251a2ebe9963ff67f21b77afd793e5792a0ad518ac2a76be5811d93"],"state_sha256":"9c92536acf99e369003a4419d173fd48e9cae6ebe52ad561e6ab8a9b83467865"}
