An ultrasound study of contextual and syllabic effects in consonant sequences produced under heavy articulatory constraint conditions

Publication date: Available online 28 October 2018Source: Speech CommunicationAuthor(s): Daniel Recasens, Clara RodríguezAbstractThe present ultrasound study investigates lingual coarticulatory resistance and differences in tongue configuration and contextual variability for consonants in syllable onset vs coda position in Catalan /iC#Ci/ sequences. In agreement with comparable ultrasound data for /aC#Ca/ sequences reported in an earlier study, coarticulatory resistance turned out to be less for /r/ (which is realized as a trill in onset position and exhibits a more tap-like realization in coda position), /l/ (which is not strongly dark), /s/ and the alveolopalatal /ɲ/ than for /p, t, n, k/. As expected, contextual variability was less for /iC#Ci/ than for /aC#Ca/ sequences due to the hi...
