However, most of the observational work on which this claim is based has concerned itself with word-initial onset consonants; little is known about how and when fricatives are mastered in word-final coda position (e.g., nose). This is all the more critical in a language like English, where word-final fricatives often carry important morphological information (e.g., toes, goes). This study examines the development of duration cues to the voicing feature contrast in coda fricatives, using longitudinal spontaneous speech data from CVC words (e.g., noise vs face) produced by three children (1;6\u20132;6 years) and six mothers. Results show that the children were remarkably adult-like in the use of duration cues to voicing contrasts in fricatives even in this early age range. Furthermore the children, like the mothers, had longer frication noise durations for morphemic compared to non-morphemic fricatives (e.g., toes vs nose) when these segments occurred in utterance-final position. These results suggest that although children's fricatives tend to be overall longer and more voiced compared to those of adults, the voicing and morphological contrasts for fricative codas are acquired early in production.<\/jats:p>","DOI":"10.1121\/1.4795772","type":"journal-article","created":{"date-parts":[[2013,5,7]],"date-time":"2013-05-07T13:11:23Z","timestamp":1367932283000},"page":"2931-2946","update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":30,"title":["Durational cues to fricative codas in 2-year-olds' American English: Voicing and morphemic factors"],"prefix":"10.1121","volume":"133","author":[{"given":"Jae","family":"Yung Song","sequence":"first","affiliation":[{"name":"University of Wisconsin\u2013Milwaukee Department of Communication Sciences and Disorders, , Milwaukee, Wisconsin 53211"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Demuth","sequence":"additional","affiliation":[{"name":"Macquarie University Department of Linguistics, Centre for Language Sciences, Australian Research Council Centre of Excellence in Cognition and its Disorders, , Sydney, New South Wales 2109, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Karen","family":"Evans","sequence":"additional","affiliation":[{"name":"University of Minnesota Department of Speech-Language-Hearing Sciences, , Minneapolis, Minnesota 55455"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefanie","family":"Shattuck-Hufnagel","sequence":"additional","affiliation":[{"name":"Speech Communication Group, Research Laboratory of Electronics, Massachusetts Institute of Technology , Cambridge, Massachusetts 02139"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"231","published-online":{"date-parts":[[2013,5,6]]},"reference":[{"key":"2023071703143910900_c1","doi-asserted-by":"publisher","first-page":"361","DOI":"10.1159\/000259973","article-title":"Complex encoding in word-final voiced and voiceless stops","volume":"36","year":"1979","journal-title":"Phonetica"},{"key":"2023071703143910900_c2","first-page":"1","volume-title":"Handbook of Phonological Development: From the Perspective of Constraint-Based Nonlinear Phonology","year":"1998"},{"key":"2023071703143910900_c3"},{"key":"2023071703143910900_c4","doi-asserted-by":"crossref","first-page":"152","DOI":"10.1044\/jshr.2301.152","article-title":"Acquisition of the voicing contrast by language-delayed and normal-speaking children","volume":"23","year":"1980","journal-title":"J.
