Researchers have found that articulation error and hypernasality have a significant effect on the degradation of CLP speech intelligibility. Motivated by this finding, the present work proposes an objective measure of sentence-level intelligibility by combining the information of articulation deficits and hypernasality. These two speech disorders represent different aspects of CLP speech. Hence, it is expected that the composite measure based on them may utilize complementary clinical information. The objective scores of articulation and hypernasality are used as features to train a regression model, and the output of the model is considered as the predicted intelligibility score. The Spearman's correlation coefficient based analysis shows a significant correlation between the predicted and perceptual intelligibility scores (\u03c1\u2009=\u20090.77, p\u2009&amp;lt;\u20090.001).<\/jats:p>","DOI":"10.1121\/1.5121310","type":"journal-article","created":{"date-parts":[[2019,8,15]],"date-time":"2019-08-15T12:34:40Z","timestamp":1565872480000},"page":"1164-1175","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":9,"title":["Objective assessment of cleft lip and palate speech intelligibility using articulation and hypernasality measures"],"prefix":"10.1121","volume":"146","author":[{"given":"Sishir","family":"Kalita","sequence":"first","affiliation":[{"name":"Department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati 1 , Guwahati, Assam 781039, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"K.
