Several tracking and aiming tasks provide objective measures of a dysarthric patient's ability to control the sound pressure level of his/her voice. These tasks can be used in experimental diagnostics aa well as in therapy. Moreover, the system contains options for the assessment of standard diagnostic parameters like maximum phonation time, maximum Ioudnes~, and average loudness of conversational speech.","PeriodicalId":408657,"journal":{"name":"Proceedings of the 15th Annual International Conference of the IEEE Engineering in Medicine and Biology Societ","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1993-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134517278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
