Purpose: The aim of this study was to determine how the speech disorder profiles in Down syndrome (DS) relate to reduced intelligibility, atypical overall quality, and impairments in the subsystems of speech production (phonation, articulation, resonance, and prosody). Method: Auditory-perceptual ratings of intelligibility, overall quality, and…

The Hindi consonant inventory, which includes the cross-linguistically rare retroflex place of articulation and four-way laryngeal contrasts, is known to pose difficulties for native English speakers. Hindi language textbooks address this challenge, in part, by providing various articulatory and acoustic descriptions of Hindi consonants, typically…

This study examined Korean learners' production of intervocalic English biconsonantal clusters consisting of /p/, /t/, /k/, /m/, /n/, or /[eng] / followed by /l/ or /[voiced alveolar approximant]/. The results of the production experiment showed several factors influencing Korean learners' production. First, Korean learners' production was…

Purpose: The purpose of this study was to examine the perception of correctly and incorrectly produced words in children with and without phonological speech sound disorder (SSD) with similar vocabulary and language skills. Method: Thirty-six monolingual English-speaking children aged 4 and 5 years, half with SSD and half with typical speech and…

Whereas many scholars have emphasized the relative importance of "comprehensibility" as an ecologically valid goal for L2 speech training, testing, and development, eliciting listeners' judgments is time-consuming. Following calls for research on more efficient L2 speech rating methods in applied linguistics, and growing attention toward…

The study aims to investigate guttural and emphatic sounds and the phenomenon of emphasis spread in Fallaahi Jordanian Arabic (FJA), a rural Jordanian dialect spoken in the north of Jordan. The study uses a non-linear approach, namely, the feature geometry approach to represent guttural and emphatic sounds and the phenomenon of emphasis spread.…

This paper explores the application of quantitative methods to study the effect of various factors on phonetic word duration in ten languages. Data on most of these languages were collected in fieldwork aiming at documenting spontaneous speech in mostly endangered languages, to be used for multiple purposes, including the preservation of cultural…

Vowel nasalization usually occurs through a two-step process whereby a vowel is nasalized via coarticulation with a nearby nasal segment; when the language later drops the nasal segment, a nasal vowel remains. Spontaneous vowel nasalization is a rare, peculiar form of nasalization that emerges in contexts that lack an historical etymological nasal…

This article provides a review of previous studies that have examined the effects of orthography on establishing contrastive phonological representations in second language acquisition and presents results from an original study on Mandarin speakers' production of English stops investigating how the presence of orthography affects the production…

Purpose: To further understand the effect of Parkinson's disease (PD) on articulatory movements in speech and to expand our knowledge of therapeutic treatment strategies, this study examined movements of the jaw, tongue blade, and tongue dorsum during sentence production with respect to speech intelligibility and compared the effect of varying…

Spoken word recognition depends on variations in fine-grained phonetics as listeners decode speech. However, many models of second language (L2) speech perception focus on units such as isolated syllables, and not on words. In two eye-tracking experiments, we investigated how fine-grained phonetic details (i.e. duration of nasalization on…

Purpose: Most acoustic and articulatory studies on /l/ have focused on either duration, formant frequencies, or tongue shape during the constriction interval. Only a limited set of data exists for the transition characteristics of /l/ to and from surrounding vowels. The aim of this study was to examine second formant (F2) transition…

We explored the proposal that overt repetition of verbal information improves the acquisition of a native accent in a second language. Mandarin-speaking Chinese learners of English were recorded while repeating and reading out English sentences before and after one of three treatments: (a) repeating native English sentences subvocally,…

Like many non-native learners, English is a Foreign Language to Omani learners; therefore, Spoken English turns out to be difficult and often problematic. Non-native learners of English face several phonological problems mainly because most languages follow specific, predictable rules of pronunciation, but English does not. There are native and…

This study is concerned with comparing the pronunciation in Southern Welsh, a Celtic language, and Cockney, an English dialect, regarding the place of articulation. The study uses a comparative method to shed light on the similarities and differences between the two accents. The data were collected from YouTube videos of speakers of Southern Welsh…
