In contrast to conventional methods that directly map noisy speech to clean speech, our method employs a lightweight helper model to estimate the noise distribution, which is then incorporated into the diffusion denoising process via a guidance mechanism. This design improves robustness by enabling seamless adaptation to unseen noise types and by leveraging large-scale DDPMs originally trained for speech generation ","authors_text":"David Burshtein, Efrayim Yanir, Sharon Gannot","cross_cats":["eess.AS"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SD","submitted_at":"2025-10-05T11:22:52Z","title":"GDiffuSE: Diffusion-based speech enhancement with noise model guidance"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2510.04157","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":"sha256:024116d881c078bb452064f2e4c8385dd9ddab8497f8566614e9fb255ed04005","target":"record","created_at":"2026-07-01T01:17:42Z","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":"866d2a6001b4e0f59d866d586feaa0aa144101063836d811353743c137e8cf1f","cross_cats_sorted":["eess.AS"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cs.SD","submitted_at":"2025-10-05T11:22:52Z","title_canon_sha256":"1bf323421f700533a316888622fa9614d15f931e2261522d8a179c4182c91996"},"schema_version":"1.0","source":{"id":"2510.04157","kind":"arxiv","version":2}},"canonical_sha256":"616bd55d38417a117c0880ca439fd33599e8d81f21b326b77d65196247c4c5de","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"616bd55d38417a117c0880ca439fd33599e8d81f21b326b77d65196247c4c5de","first_computed_at":"2026-07-01T01:17:42.007639Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-01T01:17:42.007639Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"yR6g10qNn6WFjoAdp8PbKngw6PwQdpG8RVlgkmmXA64poNwwtQwu/lRAgl5iqr6v8AgUaXRy3T47jYzYZfY/CA==","signature_status":"signed_v1","signed_at":"2026-07-01T01:17:42.008205Z","signed_message":"canonical_sha256_bytes"},"source_id":"2510.04157","source_kind":"arxiv","source_version":2}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:024116d881c078bb452064f2e4c8385dd9ddab8497f8566614e9fb255ed04005","sha256:fe37e9f64ed897a08006da4d3d14092fc0a574b1efa9100e8fd763941f0d8b99"],"state_sha256":"c0a3dfe7fdc28ad17cfb2364f7bdf3516819a70a5cd86c0769e9fc9b4ef35469"}
