Existing KWS search algorithms typically follow a frame-synchronous approach, where search decisions are made repeatedly at each frame despite the fact that most frames are keyword-irrelevant. In this paper, we propose TDT-KWS, which leverages token-and-duration Transducers (TDT) for KWS tasks. We also propose a novel KWS task-specific decoding algorithm for Transducer-based models, which supports highly effective fram","authors_text":"Baochen Yang, Hainan Xu, Hao Li, Haoyu Li, Kai Yu, Yu Xi","cross_cats":["cs.SD"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2024-03-20T06:24:25Z","title":"TDT-KWS: Fast And Accurate Keyword Spotting Using Token-and-duration Transducer"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2403.13332","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:dad58a5011477f1dc21a61d54e52617ecfb0c865ee4af20ecab27442318af5de","target":"record","created_at":"2026-07-05T07:58:34Z","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":"6d115716ad814987bdf3f650620a04a7ac37708c2d3b7d39fbbc86f496829288","cross_cats_sorted":["cs.SD"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"eess.AS","submitted_at":"2024-03-20T06:24:25Z","title_canon_sha256":"8e888268820e3a639e451a6647e89133e7500147293fe576c076b5a80569358e"},"schema_version":"1.0","source":{"id":"2403.13332","kind":"arxiv","version":1}},"canonical_sha256":"473217da07e2fe90ecea7c84b5bb436bc85df4488168ee3fbc47dfc9e9016410","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"473217da07e2fe90ecea7c84b5bb436bc85df4488168ee3fbc47dfc9e9016410","first_computed_at":"2026-07-05T07:58:34.892139Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T07:58:34.892139Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"5ES8X+gsiH360kCECYWWqeZ/7MAW/CWT+MCVQcdCeyxswHSPfVW40RybRK+B1mGPeysvP/EB5utHNkb6eX06Aw==","signature_status":"signed_v1","signed_at":"2026-07-05T07:58:34.892622Z","signed_message":"canonical_sha256_bytes"},"source_id":"2403.13332","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:dad58a5011477f1dc21a61d54e52617ecfb0c865ee4af20ecab27442318af5de","sha256:abc7fdfcf9bb1a73e0f50af70de34a5b7f79fbc419f038fde46272caf54ed64c"],"state_sha256":"6d87855d8f91e572ee9807a8ef27ab79440fe71148d12d4679ff21efac24ee42"}
