We investigate whether hallucinations can be detected and mitigated through Whisper's internal representations. We extract audio encoder activations and evaluate two representation spaces: raw Whisper activations and Sparse AutoEncoder (SAE) latents. We show that both spaces encode linearly separable hallucination-related information, with discriminative power concentrated in a sparse feature subset and increasing toward deep","authors_text":"Assel Yermekova, Georgii Aparin, Tasnima Sadekova, Vadim Popov","cross_cats":["cs.AI"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2026-06-05T17:26:23Z","title":"Whisper Hallucination Detection and Mitigation via Hidden Representation Steering and Sparse AutoEncoders"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.07473","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:bbcda2aa3e62ea761f1f8530db04a964af80ad48be6e9aac1932b7f898d1c9ca","target":"record","created_at":"2026-06-08T01:05:29Z","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":"03c6b43a9627e89c14278ad5a0583ffa13cc49a996fc66e73ba231484309fbd9","cross_cats_sorted":["cs.AI"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.SD","submitted_at":"2026-06-05T17:26:23Z","title_canon_sha256":"e9967696a5aad39747a7ebf0c33ef9d1ed2bab9617b6347cacdcc7748b9d0c95"},"schema_version":"1.0","source":{"id":"2606.07473","kind":"arxiv","version":1}},"canonical_sha256":"497291434d16ba41f170b39d72d0a76605b99728615b6ccee51ec92608327207","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"497291434d16ba41f170b39d72d0a76605b99728615b6ccee51ec92608327207","first_computed_at":"2026-06-08T01:05:29.183006Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-08T01:05:29.183006Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"hiRtMWrwaBZBccCvCdOZgFlQhejO2RA4UDYbHisG78rE0/yPDseDGOJoQ7d4MCACEmC/uSBPsXU9g0YSP7vBAA==","signature_status":"signed_v1","signed_at":"2026-06-08T01:05:29.183979Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.07473","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:bbcda2aa3e62ea761f1f8530db04a964af80ad48be6e9aac1932b7f898d1c9ca","sha256:1758f717d619382c8423abf1104e168d7a1c2286c693e2f3bbce7966bf218c21"],"state_sha256":"00b58880a185e2f75b60a76b711cf61af5f1e5eb6fff48e091986d1b7508e66e"}
