Speech disturbance is clinically diagnosed, but methods for objective assessment of severity are lacking. Using 71 sets of speech recordings from ataxia patients, we developed an automated classification system. With a tolerance of \u00b11 point, this classification system correctly predicted experts\u2019 ratings of speech disturbance according to item 4 of the Scale for Assessment and rating of ataxia (SARA) in 80% of cases. We thereby demonstrate feasibility of computer-assisted voice analysis for automated assessment of severity of speech disturbance.<\/jats:p>","DOI":"10.1038\/s41746-023-00787-x","type":"journal-article","created":{"date-parts":[[2023,3,26]],"date-time":"2023-03-26T19:55:44Z","timestamp":1679860544000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["SARAspeech\u2014Feasibility of automated assessment of ataxic speech disturbance"],"prefix":"10.1038","volume":"6","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-1808-2134","authenticated-orcid":false,"given":"M.","family":"Grobe-Einsler","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3265-0262","authenticated-orcid":false,"given":"J.","family":"Faber","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Taheri","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Kybelka","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Raue","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"J.","family":"Volkening","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F.","family":"Helmhold","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2280-7273","authenticated-orcid":false,"given":"M.","family":"Synofzik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"T.","family":"Klockgether","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2023,3,16]]},"reference":[{"key":"787_CR1","doi-asserted-by":"publisher","first-page":"28","DOI":"10.1055\/s-2007-999122","volume":"60","author":"H Ackermann","year":"1992","unstructured":"Ackermann, H. & Ziegler, W.
