In practice, stress, channel noise, and automatic speech recognition errors mangle the transcripts badly enough that rule-based systems fail. SeaAlert attacks the problem with two components: a transformer-based classifier that rates distress severity, and an LLM-based extractor that pulls structured fields from noisy text. Because labeled real-world distress recordings are scarce, the researchers built a synthetic pipeline — an LLM generates diverse distress messages, including ones that deliberately omit standard codewords, which are then converted to speech, degraded with simulated VHF noise, and transcribed.\n\nThe results matter because coast guard and maritime rescue coordination depends on fast, accurate intake of exactly the kind of information these calls are supposed to carry. Transformer classification held up better under noise and missing codewords than lexical baselines, and LLM extraction outperformed regex on the messiest structured fields — two findings that suggest learned representations handle real-world degradation better than hand-crafted rules.\n\nSeaAlert is a controlled experimental framework, not a deployed system, so the gap between synthetic training data and genuine distress recordings remains an open question — one the authors acknowledge but cannot fully close without more labeled real-world data.","[\"ai\",\"maritime\",\"nlp\",\"safety\"]","2026-07-07T04:00:00.000Z","2026-07-07T20:07:30.878Z","2026-07-07T20:07:33.788Z","published",null,[],"ai",[24,26,27,28],"maritime","nlp","safety",[30],{"name":31,"url":32},"arXiv cs.AI","https:\u002F\u002Farxiv.org\u002Fabs\u002F2604.14163",0,{"sections":35},[36,40,45,50,55,60,65,70,75,79,84,88,93,98],{"name":37,"slug":24,"count":38,"latest_published_at":39},"AI",2590,"2026-07-16T04:00:00.000Z",{"name":41,"slug":42,"count":43,"latest_published_at":44},"Security","security",294,"2026-07-15T19:59:48.000Z",{"name":46,"slug":47,"count":48,"latest_published_at":49},"Deals","deals",179,"2026-06-29T20:02:07.000Z",{"name":51,"slug":52,"count":53,"latest_published_at":54},"Policy","policy",158,"2026-07-16T00:02:48.000Z",{"name":56,"slug":57,"count":58,"latest_published_at":59},"Hardware","hardware",122,"2026-07-14T19:46:26.000Z",{"name":61,"slug":62,"count":63,"latest_published_at":64},"Consumer Tech","consumer-tech",93,"2026-07-13T13:20:48.000Z",{"name":66,"slug":67,"count":68,"latest_published_at":69},"Software","software",70,"2026-07-13T19:52:25.000Z",{"name":71,"slug":72,"count":73,"latest_published_at":74},"Science","science",66,"2026-07-10T10:29:37.000Z",{"name":76,"slug":77,"count":78,"latest_published_at":18},"Dev Tools","dev-tools",59,{"name":80,"slug":81,"count":82,"latest_published_at":83},"Gaming","gaming",41,"2026-07-09T04:00:00.000Z",{"name":85,"slug":86,"count":82,"latest_published_at":87},"Startups","startups","2026-06-29T20:55:50.000Z",{"name":89,"slug":90,"count":91,"latest_published_at":92},"General","general",29,"2026-07-10T22:28:58.000Z",{"name":94,"slug":95,"count":96,"latest_published_at":97},"Reviews","reviews",20,"2026-06-24T12:00:01.000Z",{"name":99,"slug":100,"count":101,"latest_published_at":102},"How-To","how-to",6,"2026-06-16T09:00:00.000Z"]
