Coarticulation patterns were investigated from read samples of consonant-vowel sequences in monosyllabic words containing a variety of consonants and vowels. This was done by examining F<sub>2<\/sub> vowel onsets and F<sub>2<\/sub> vowel targets, plotted as F<sub>2<\/sub> locus equations. Data were processed for between-sibling differences using a number of statistical tests. Results indicated that the MZ twins displayed F<sub>2<\/sub> parameters and coarticulation patterns which were more similar than those of their age- and sex-matched sibling. The results of this case study therefore suggest that acoustic phonetic parameters used to index coarticulation patterns have the potential to profile some of the similarities and differences in the speech characteristics of genetically related individuals.<\/jats:p>","DOI":"10.1159\/000076377","type":"journal-article","created":{"date-parts":[[2004,3,9]],"date-time":"2004-03-09T15:17:39Z","timestamp":1078845459000},"page":"273-297","source":"Crossref","is-referenced-by-count":13,"title":["Speech Characteristics of Monozygotic Twins and a Same-Sex Sibling: An Acoustic Case Study of Coarticulation Patterns in Read Speech"],"prefix":"10.1515","volume":"60","author":[{"given":"S.P.","family":"Whiteside","sequence":"first","affiliation":[{"name":"Department of Human Communication Sciences , University of Sheffield, Sheffield and a Speech and Language Therapy Department , Chorlton Health Centre, Manchester , United Kingdom"}]},{"given":"E.","family":"Rixon","sequence":"additional","affiliation":[{"name":"Department of Human Communication Sciences , University of Sheffield, Sheffield and a Speech and Language Therapy Department , Chorlton Health Centre, Manchester , United Kingdom"}]}],"member":"374","published-online":{"date-parts":[[2004,3,5]]},"reference":[{"key":"2021062305162923166_j_000076377_ref_001_w2aab3b7b8b1b6b1ab1ab1Aa","doi-asserted-by":"crossref","unstructured":"Chow, G.C.: Tests of equality between sets of coefficients in two linear regressions.
