An electro-palatographic study of consonant sequences in Iwaidja
نویسندگان
چکیده
An EPG (electro-palatographic) corpus of Iwaidja consonant sequences was examined to investigate global consonant timing patterns and the extent of coarticulation and coproduction in nasal+stop and lateral+stop clusters. As observed in other Australian languages (e.g. Warlpiri), there was limited anticipatory coarticulation in certain heterorganic sequences and evidence of coarticulatory resistance in others. Furthermore lateral clusters patterned differently from nasal clusters. In addition to biomechanical constraints implied by the DAC (Degree of Articulatory Constraint) model, phonological structures of the language including place and manner features clearly influence the extent of coproduction and subsequent spatial modification of consonant gestures in Iwaidja consonant sequences.

Optimality Theoretic Account of Acquisition of Consonant Clusters of English Syllables by Persian EFL Learners*
This study accounts for the acquisition of the consonant clusters of English syllable structures both in onset and coda positions by Persian EFL learners. Persian syllable structure is "CV(CC)", composed of one consonant at the initial position and two optional consonants at the final position; whereas English syllable structure is "(CCC)V(CCCC)". Therefore, Persian EFL learners need to resolve...
متن کاملSyllable structure in Old, Middle and Modern Persian: A contrastive analysis
Evolution of languages has always been of interest to linguists. In this paper we study the natural progress of the syllable structure from Old Persian (O.P) to Middle Persian (Mi.P) and up to the Modern Persian (Mo.P). For this purpose all the words containing consonant sequences are collected from specific sources of each of these languages, and then analysed according to the syllab...
متن کاملPre-final version: Durational correlates for differentiating consonant sequences in Russian 1 Durational correlates for differentiating consonant sequences in Russian
In Russian, the same consonant sequences are permitted in various phonotactic environments. The presence of a word boundary or reduced vowel can be phonologically contrastive, and both learners and experienced listeners may rely on fine acoustic cues to discriminate between phonotactic possibilities. In this study, durational characteristics of consonant sequences are examined to establish whet...
متن کاملAssimilation of Final Low Back Vowel in Eghlidian Dialect
In this article, the low back vowel /A/ in word-final positions in Eghlidian dialect, one of Persian dialects, is studied. This vowel is represented phonetically as [A], [o] and [@] in different phonetic environments. Therefore many words were collected via interviewing ten native speakers so that these different alternant forms can be accounted for appropriately. Since one of the authors of th...
متن کاملThe Effect of Stress and Speech Rate on Vowel Coarticulation in Catalan Vowel-Consonant-Vowel Sequences.
PURPOSE The goal of this study was to ascertain the effect of changes in stress and speech rate on vowel coarticulation in vowel-consonant-vowel sequences. METHOD Data on second formant coarticulatory effects as a function of changing /i/ versus /a/ were collected for five Catalan speakers' productions of vowel-consonant-vowel sequences with the fixed vowels /i/ and /a/ and consonants: the ap...
