Objective To analyze speech and linguistic features in children with articulation disorder characterized by consonant and vowel phonological errors. Methods Between February 2007 and June 2015, 117 children who showed articulation disorder were selected for the study. Based on comprehensive speech and language assessments, the subjects were classified into articulation dysfunction (AD), or AD...

This study examined whether visually presented bilabials consonants are better identified than velars in a CV (C = consonant; V = vowel) or VCV context. We also investigated whether voiced and voiceless consonants sharing a same place and manner of articulation could be differentiated from each other with visual cues only. Although it is generally assumed that voicing is mainly mediated by the ...

This study presents an overview of the different strategies that Persian learners of English employ to deal with initial clusters. While vowel epenthesis appears to be the most widespread repair strategy to conform such clusters to Persian phonotactics, the location of the epenthetic vowel varies. In this paper, we investigate two approaches that seek to explain the epenthetic site. The first o...

BACKGROUND Studies addressing the identification of sung vowels concern mainly the effect of the fundamental frequency (f0) and conclude that correct vowel identification decreases with increasing pitch. In one experiment, the impact of consonantal environment on the intelligibility of the vowels in high-pitched singing was also studied. The results of that experiment showed positive effect of ...

in this paper, the validity of the key prediction of adaptive dispersion theory was tested. according to this prediction, vowels of a given language are organized in such a way that they are sufficiently distinct on the perceptual level. it implies that more crowded inventories, which also have wider f1 dimension, occupy greater vowel spaces than inventories with fewer vowels.  to investigate t...

acoustic analysis of sounds produced during speech provides significant information about the physiology of larynx and vocal tract. the analysis of voice power spectrum is a fundamental sensitive method of acoustic assessment that provides valuable information about the voice source and characteristics of vocal tract resonance cavities. the changes in long-term average spectrum (ltas) spectral ...

The decompositional, non-lexicalist, approach to word-structure and the theory of roots have proven highly rewarding. One grey area, however, comes from Romance since, rather than roots, word structure primitive appears be stem: root + ‘stem-formative/theme vowel’. Regardless, there been perspicacious decompositional accounts Italian, however these are still marred by large number morphological...
