Such systems should be able to enrol (E), verify (V), and identify (I) new and recurring users based on their personal information, e.g. postcode, name, and date of birth. In this work, we formalise the three authentication tasks and their evaluation protocols, and we present EVI, a challenging spoken multilingual dataset with 5,506 dialogues in English, Polish, and French. Our proposed models set the first competitive benchmarks, explore the challenges of multilingual natural language processing of spoken dialogue, and set directions for future research.","url_abs":"https://arxiv.org/abs/2204.13496v1","url_pdf":"https://arxiv.org/pdf/2204.13496v1.pdf","source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28","licence_url":"https://creativecommons.org/licenses/by-sa/4.0/legalcode","row_kind":"abstracts"},"code_links":[{"paper_slug":"evi-multilingual-spoken-dialogue-tasks-and-1","repo_url":"https://github.com/PolyAI-LDN/evi-paper","is_official":1,"mentioned_in_paper":0,"mentioned_in_github":1,"framework":"none","reach":{"status":"ok","spdx":"CC-BY-4.0"}}],"tasks":[{"task_slug":"speaker-identification","task_name":"Speaker Identification"},{"task_slug":"speaker-verification","task_name":"Speaker Verification"},{"task_slug":"spoken-dialogue-systems","task_name":"Spoken Dialogue Systems"}],"methods":[],"datasets_introduced":[],"methods_introduced":[],"results":[{"leaderboard":"/sota/speaker-identification-on-evi-en-gb-1","task":"Speaker Identification","dataset":"EVI en-GB","model":"Fuzzy Retrieval","rank_in_archive_order":1,"of":1,"metrics":{"Top-1 (%)":"67.77"},"uses_additional_data":false},{"leaderboard":"/sota/speaker-identification-on-evi-fr-fr","task":"Speaker Identification","dataset":"EVI fr-FR","model":"Fuzzy Retrieval","rank_in_archive_order":1,"of":1,"metrics":{"Top-1 (%)":"80.83"},"uses_additional_data":false},{"leaderboard":"/sota/speaker-identification-on-evi-pl-pl","task":"Speaker Identification","dataset":"EVI pl-PL","model":"Fuzzy Retrieval","rank_in_archive_order":1,"of":1,"metrics":{"Top-1 (%)":"95.13"},"uses_additional_data":false}],"syntology":{"syntology_url":null,"atlas_url":"https://app.syntology.ai/?focus=2204.13496","mcp":null,"developers":"https://syntology.ai/developers"},"arxiv_metadata":null,"syntology_extracted_results":null}
