The speech region around the g landmark is used to compute two different acoustic features, namely, two-dimensional discrete cosine transform based joint spectro-temporal features, and Mel-frequency cepstral coefficients. Sentence-specific acoustic models are built using these features extracted from the normal speakers' group. The mean log-likelihood score for each test utterance is computed and tested as the acoustic correlates of intelligibility. Derived intelligibility measure shows significant correlation (\u03c1\u2009=\u20090.78, p\u2009&amp;lt;\u20090.001) with the perceptual ratings.<\/jats:p>","DOI":"10.1121\/1.5062838","type":"journal-article","created":{"date-parts":[[2018,11,6]],"date-time":"2018-11-06T17:21:35Z","timestamp":1541524895000},"page":"2656-2661","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":7,"title":["Importance of glottis landmarks for the assessment of cleft lip and palate speech intelligibility"],"prefix":"10.1121","volume":"144","author":[{"given":"Sishir","family":"Kalita","sequence":"first","affiliation":[{"name":"Department of Electronics and Electrical Engineering, Indian Institute of Technology Guwahati , Guwahati, Assam 781039, India"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S.
