We particularly focus on far-field text-dependent SV from single (task1) and multiple microphone arrays (task3). The major challenges in such scenarios are short utterance and cross-channel and distance mismatch for enrollment and test. With the belief that better speaker embedding can alleviate the effects from short utterance, we introduce a new speaker embedding architecture - ResNet-BAM, which integrates a bottleneck attention module with ResNet as a simple and efficient way ","authors_text":"Jian Wu, Lei Xie, Li Zhang","cross_cats":["cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2020-08-08T13:32:48Z","title":"NPU Speaker Verification System for INTERSPEECH 2020 Far-Field Speaker Verification Challenge"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2008.03521","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":"sha256:338a4b702f8b1b687b7f5e128368ec4e2a8de92129a51bb5e2d63b4ee0f2d6a7","target":"record","created_at":"2026-07-05T01:25:42Z","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":"40797f4f075b4046a6ea11c27342d5ad3ce93d1b627de9b28a7baf73c63951f2","cross_cats_sorted":["cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2020-08-08T13:32:48Z","title_canon_sha256":"8bc8ee192991112b992e0ba77f2d7e425c7db7e0475a685480e8a8c820158619"},"schema_version":"1.0","source":{"id":"2008.03521","kind":"arxiv","version":1}},"canonical_sha256":"cf160909787187d09c80bfbed33503c7035c50674ce93bcb4aca39bf55d10313","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"cf160909787187d09c80bfbed33503c7035c50674ce93bcb4aca39bf55d10313","first_computed_at":"2026-07-05T01:25:42.694447Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T01:25:42.694447Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"gjZxDqoej9rM/99FCHx9RqS6Su/cSMxQylEdBV/7xhhY+v6QqHhsg6mtPue7SNRXvz+heiXOlRrTE6iRJM1hCg==","signature_status":"signed_v1","signed_at":"2026-07-05T01:25:42.694832Z","signed_message":"canonical_sha256_bytes"},"source_id":"2008.03521","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:338a4b702f8b1b687b7f5e128368ec4e2a8de92129a51bb5e2d63b4ee0f2d6a7","sha256:8794a08f6f89e2e6521e8439649276cfc35d25f61d633deb48b8fce4e7108e5f"],"state_sha256":"5c4b4d28bcbeed984506362aef5210ca4f2c1ef9a3595b479af9440294fa1036"}
