To better understand these impairments, natural acoustic speech stimuli that were masked in speech-shaped noise at various intensities were presented to dyslexic, AN, and control subjects either in isolation or accompanied by visual articulatory cues. AN subjects were expected to benefit from the pairing of visual articulatory cues and auditory CV stimuli, provided that their speech perception impairment reflects a relatively peripheral auditory disorder. Assuming that dyslexia reflects a general impairment of speech processing rather than a disorder of audition, dyslexics were not expected to similarly benefit from an introduction of visual articulatory cues. The results revealed an increased effect of noise masking on the perception of isolated acoustic stimuli by both dyslexic and AN subjects. More importantly, dyslexics showed less effective use of visual articulatory cues in identifying masked speech stimuli and lower visual baseline performance relative to AN subjects and controls. Last, a significant positive correlation was found between reading ability and the ameliorating effect of visual articulatory cues on speech perception in noise. These results suggest that some reading impairments may stem from a central deficit of speech processing.<\/jats:p>","DOI":"10.1121\/1.1940509","type":"journal-article","created":{"date-parts":[[2005,8,5]],"date-time":"2005-08-05T17:37:53Z","timestamp":1123263473000},"page":"1122-1133","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":31,"title":["Using auditory-visual speech to probe the basis of noise-impaired consonant\u2013vowel perception in dyslexia and auditory neuropathy"],"prefix":"10.1121","volume":"118","author":[{"given":"Joshua","family":"Ramirez","sequence":"first","affiliation":[{"name":"University of California Cognitive Science, , Irvine, 3151 Social Science Plaza, Irvine, California 92697"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Virginia","family":"Mann","sequence":"additional","affiliation":[{"name":"University of California Cognitive Science, , Irvine, 3151 Social Science Plaza, Irvine, California 92697"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","reference":[{"key":"2023073120311114900_c1","doi-asserted-by":"crossref","first-page":"345","DOI":"10.1016\/0022-0965(83)90087-5","article-title":"Speech perception and memory coding in relation to reading ability","volume":"35","year":"1983","journal-title":"J.
