A prominent hypothesis holds that by speaking to infants in infant-directed speech (IDS) as opposed to adult-directed speech (ADS), parents help them learn phonetic categories. Specifically, two characteristics of IDS have been claimed to facilitate learning: "hyperarticulation," which makes the categories more "separable," and…

Purpose: This article describes the developmental trajectories of four communication-related parameters (i.e., intelligibility, articulation rate, fluency, and communicative efficiency) in a cross-sectional study of typically developing children between 3 and 9 years. The four target parameters were related to auditory-perceptual parameters of…

Purpose: We compare teens' and adults' imitation of sentences with shortened and lengthened voice onset time (VOT), in order to test whether purported age-based advantages in phonetic acquisition may be due to differences in imitative ability. Method: Teens (M[subscript age] = 13, n = 39) and adults (n = 31) completed an explicit imitation and…

This article investigates the production of the emphatic consonants /?, ?, ?/ by typically developing Jordanian children. Sixty typically developing monolingual Ammani Arabic-speaking children (30 boys and 30 girls) with ages ranging from 2 to 7;11 years were recruited in a production experiment. In the experiment, they were asked to produce 18…

The current study examines second dialect acquisition of North Korean refugees living in Seoul. A total of 14478 stops were measured from each of 22 Pyongyang North Korean standard (NK) and Seoul South Korean (SK) speakers. First, stops of NK and SK have been directly compared to each other by measuring VOT, F0, and H1-H2. In addition to providing…

This work examined speech and language skills of a cohort of children with unilateral and bilateral mild/moderate hearing loss at time of discharge from preschool therapy services as they were transitioning to the school system. The study consisted of a retrospective chart review of children born between 2003 and 2011 and identified with a…

While phonetic training in laboratory settings has been shown to be helpful for second language (L2) sounds learning in prior studies , it is still open to debate whether a perception- or a production-based approach can better help adults learn L2 sounds in classroom settings. This study aimed to fill this knowledge gap. The participants were…

English language instructing that simply underscored on punctuation and jargon adapting as opposed to elocution learning had basically held up the second semester understudies in Islamic schools. Understudies imagined that elocution is something hard to learn in light of the fact that they are infrequently shown articulation in the homeroom.…

Covert contrast is the statistically reliable distinction between target language phonemes produced in the process of language acquisition that is nevertheless not perceived by a native speaker of that language. This paper examines the acquisition of contrasts in four Najdi Arabic fricatives, /s/, /[voiceless palato-alveolar fricative]/,…

This article presents the process and results of an action research project which explored the contribution of information gap activities to support a group Honduran ninth-graders' speaking fluency. Their speaking fluency was assessed in terms of speech rate, breakdowns or pauses, and repairs. This study adopted a mixed method approach:…

Nonmanual articulations in sign languages range from being semantically impoverished to semantically rich, and from being independent of manual articulations to coordinated with them. But, while this range has been well noted, certain nonmanuals remain understudied. Of particular interest to us are nonmanual articulations coordinated with manual…

Purpose: The aim of this study was to assess the frequency and types of compensatory articulations (CAs) in nonsyndromic patients with velopharyngeal dysfunction (VPD) and various palatal anomalies and to determine the relationship between the frequency of CAs, type of palatal anomaly, and phonological errors. Method: A total of 783 nonsyndromic,…

Purpose: Deep brain stimulation (DBS) is often successful in alleviating motor symptoms of essential tremor (ET); however, DBS may also induce adverse speech effects. The caudal zona incerta (cZi) is a promising DBS target for tremor, but less is known about the consequences of cZi DBS for speech. This preliminary study examined how habitual cZi…

This paper analyses disfluencies and ungrammatical expressions in the speech of 11-13-year-old Finnish-speaking boys with ASD (N = 5) and with neurotypical development (N = 6). The ASD data were from authentic group therapy sessions and neurotypical data from teacher-led group discussions. The proportion of disfluencies and ungrammatical…

No prevalence statistics for articulation and phonological problems in Arabic children with Down syndrome (DS) have been published. The goal of this study was to see how common consonant production errors and phonological processes are in Emirati Arabic-speaking children with DS, and how they relate to their intellectual level and hearing status.…
