We propose a two-stage reconstruction task (Xi to Yi to Xi) using synthetic specific-speaker speeches as intermedium features, where A2A VC is divided into two stages: any-to-one (A2O) and one-to-Any (O2A). In the A2O stage, we propose a new A2O method: SingleVC, by employing a noval data augment strategy(pitch-shifted and duration-remained","authors_text":"Xianfeng Zhao, Xiaowei Yi, Yewei Gu, Zhenyu Zhang","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2021-10-06T04:29:31Z","title":"MediumVC: Any-to-any voice conversion using synthetic specific-speaker speeches as intermedium features"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2110.02500","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:f011757cc737d143c9d5ca3a0d665cfbdd0cd87b60f40b3afaafc2756c2d2bae","target":"record","created_at":"2026-07-05T03:20:27Z","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":"d98bd484143e82b6d0d9a7aba8984f6d167c9df49e961302a8f2016375f8e7a3","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by/4.0/","primary_cat":"eess.AS","submitted_at":"2021-10-06T04:29:31Z","title_canon_sha256":"462a02bd294d4c8ee054d8f29664e973e26c19a6f69e8d07719bb1744c7cfc97"},"schema_version":"1.0","source":{"id":"2110.02500","kind":"arxiv","version":1}},"canonical_sha256":"706a6a33742093989eaec8e2dbd2d1224ccad124b22b116ba84731a8444a8c1f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"706a6a33742093989eaec8e2dbd2d1224ccad124b22b116ba84731a8444a8c1f","first_computed_at":"2026-07-05T03:20:27.021559Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:20:27.021559Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"1P+pZuHSsaqvJ9swnOcsBj/VNLRChs0EW49bbmJFTSg0c0fE7u5KtboAlnQkS6kGT/821T9XMhJDOxOEO0WOCw==","signature_status":"signed_v1","signed_at":"2026-07-05T03:20:27.021984Z","signed_message":"canonical_sha256_bytes"},"source_id":"2110.02500","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:f011757cc737d143c9d5ca3a0d665cfbdd0cd87b60f40b3afaafc2756c2d2bae","sha256:6b6c42cb1d839d5d58f12a9165c51c57e68bd0a188175b861ce7695c7f87200e"],"state_sha256":"75bf5c74c4f310ad56e785fd75dc6d281e22ca619031f51a81d443a155cdc1c2"}
