Mandarin has a much more limited segmental inventory than English, and permits only nasals in coda position, presenting a challenge for learners of English. However, previous studies have mainly explored this issue using perceptual transcription. This study provides an acoustic analysis of coda consonant productions by Mandarin L2 learners of Australian English. The results indicate that they p...

1 A challenge for OT 1.1 Compensatory lengthening as weight conservation Compensatory lengthening occurs when the featural content of a nucleus or moraic coda is deleted, or becomes reaffiliated with a nonmoraic position — typically an onset — and the vacated mora, instead of being lost, is retained with new content (Hayes 1989). Compensatory lengthening is most often triggered by the deletion ...

Children's early word productions often differ from the target form, sometimes exhibiting vowel lengthening when word-final coda consonants are omitted (e.g., dog /dog/ --> [d(c):]). It has typically been assumed that such minimal words lengthening compensates for a missing prosodic unit (a mora). However, this study raises the alternative hypothesis that vowel lengthening in early productions ...

The 'social complexity hypothesis' suggests that complex social structure is a driver of diversity in animal communication systems. Sperm whales have a hierarchically structured society in which the largest affiliative structures, the vocal clans, are marked on ocean-basin scales by culturally transmitted dialects of acoustic signals known as 'codas'. We examined variation in coda repertoires a...

BACKGROUND In order to understand how biological systems function it is necessary to determine the interactions and associations between proteins. Gene fusion prediction is one approach to detection of such functional relationships. Its use is however known to be problematic in higher eukaryotic genomes due to the presence of large homologous domain families. Here we introduce CODA (Co-Occurren...

This paper reports the acoustic experiment and perception test on a pair of Cantonese long and short vowels /a/ and /ɐ/ in the diphthong context. The acoustic data show that [aːi] and [ɐi] have similar targets of vowel nucleus and coda, parallel transition glide, and comparable total duration. They are different in their durational structure: [aːi] has a long steady phrase of vowel nucleus whi...

BACKGROUND phonological disorders. AIM to verify the occurrence of vocalic lengthening, through acoustic analysis, in a group of 16 children (8 boys and 8 girls) with evolutive phonological disorders (EPD), who did not present in their speech /R/ and /S/ medial codas; to verify the occurrence percentage of lengthening and omission strategies in the two types of coda. METHOD recordings of 16...

The aims of this study are (1) to determine the acoustic pattern signaling that a syllable in Standard Chinese, SC, contains a nasal coda, and (2) specify the acoustic attributes that distinguish between the two places of articulation for a nasal coda. The "rst syllable in SC disyllabic words with simple vowels [a], [i], and [ə] was examined in di!erent contexts: (1) vowel with a nasal coda [n]...
