We focus on the recognition of Frisian-Dutch radio broadcasts where one of the mixed languages, namely Frisian, is under-resourced. Recently, we have explored how the acoustic modeling (AM) can benefit from monolingual speech data belonging to the high-resourced mixed language. For this purpose, we have trained state-of-the-art AMs on a significantly increased amount of CS speech by applying automatic transcr","authors_text":"David A. van Leeuwen, Emre Y{\\i}lmaz, Henk van den Heuvel","cross_cats":[],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-07-28T15:16:33Z","title":"Code-Switching Detection with Data-Augmented Acoustic and Language Models"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1808.00521","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":"sha256:7119472f7351fad75dec08ba00f988f892596a4a5befcede0aa0479e9ceefdec","target":"record","created_at":"2026-05-18T00:09:05Z","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":"536e902203ebe14ba48dbd0afde09e2dfb6fcb6d99a73024b856ef9b9d22154f","cross_cats_sorted":[],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"cs.CL","submitted_at":"2018-07-28T15:16:33Z","title_canon_sha256":"b0c6f6d7cac2ea7d0c7293566b6a83c2aee3eae55d88f0bb6c56c643e9b2d86f"},"schema_version":"1.0","source":{"id":"1808.00521","kind":"arxiv","version":1}},"canonical_sha256":"b223e8ff9b85a4df3d360a905913567462fb65a19dadaa4edb0277c36604d0b2","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"b223e8ff9b85a4df3d360a905913567462fb65a19dadaa4edb0277c36604d0b2","first_computed_at":"2026-05-18T00:09:05.071215Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-18T00:09:05.071215Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"9HaGu8Au74HRChpFbr1laXzaJw24msoVjbpx5OUtdcvqZt6RNMw5yjtWPBdsTREXZ5WmYNGOurOz5GvJiRt4Bw==","signature_status":"signed_v1","signed_at":"2026-05-18T00:09:05.071929Z","signed_message":"canonical_sha256_bytes"},"source_id":"1808.00521","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:7119472f7351fad75dec08ba00f988f892596a4a5befcede0aa0479e9ceefdec","sha256:a5030fdec23f30bb3144c219e809f1d2d52cc3a33f7d52ec57b47ca78aea82fb"],"state_sha256":"ef43fccba0dd404a72033f949b13b012c66d7c1f5a3a88a59e9d5a33627b2f3e"}
