This study examined how intervention dose frequency affects phonological acquisition and generalization in preschool children with speech sound disorders (SSD). Using a multiple-baseline, single-participants experimental design, eight English-speaking children with SSD (4;0 to 5;6) were split into two dose frequency conditions (4…

Purpose: The aim of the study was to investigate the relationship between language load and articulatory variability in children with language and speech sound disorders, including childhood apraxia of speech. Method: Forty-six children, ages 48-92 months, participated in the current study, including children with speech sound disorder,…

Pattern activities have a crucial role in supporting early academic and language skills related to cognitive development, as they play a key role in understanding mathematical ideas and relationships, and in understanding the order, logic and concepts of mathematics. From this point of view, the research was conducted to investigate the effect of…

Non-native phoneme perception can be challenging for adult learners. This article explores two routes to strengthening early representations of non-native targets: perceptual training, which focuses on auditory discrimination of novel contrasts, and articulatory training, which highlights the articulatory gestures of non-native categories. Of…

Purpose: This retrospective study was intended to replicate findings from Sacks et al. (2013) regarding the efficacy of using the SATPAC (Systematic Articulation Training Program Accessing Computers) approach for remediating speech sound errors in a Tier 3 response to intervention (RTI) context. Method: Nine children aged 7;7 (years;months) to…

In the beginning, humans had a tongue ("gjuhën," "Shqip"). Then, they could or couldn't let go of the tongue ("len…gjuhën," Shqip). Albanian natural tongue (Shqip) implies the use of the tongue in the mouth for articulating ("shqiptoj," Shqip) words. The eternity of Shqip (Speech) is in its words that are…

Purpose: Age-related sensorineural hearing loss can dramatically affect speech recognition performance due to reduced audibility and suprathreshold distortion of spectrotemporal information. Normal aging produces changes within the central auditory system that impose further distortions. The goal of this study was to characterize the effects of…

Purpose: Real-time magnetic resonance imaging (MRI) and accompanying analytical methods are shown to capture and quantify salient aspects of apraxic speech, substantiating and expanding upon evidence provided by clinical observation and acoustic and kinematic data. Analysis of apraxic speech errors within a dynamic systems framework is provided…

Purpose: This study examined the relationship between the magnitude of neck-surface vibration (NSV[subscript Mag]; transduced with an accelerometer) and intraoral estimates of subglottal pressure (P'[subscript sg]) during variations in vocal effort at 3 intensity levels. Method: Twelve vocally healthy adults produced strings of /p?/ syllables in 3…

This dissertation investigates Voice Onset Time (VOT), which serves as an essential property for differentiating plosive consonants in L1 and L2 Mandarin Chinese. It surveys VOT variations and demonstrates that they are affected by several phonetic and phonological properties, e.g., lexical tone, place of articulation (POA), speech rate,…

Purpose: Specific language impairment (SLI) is characterized by a delay in language acquisition despite a lack of other developmental delays or hearing loss. Genetics of SLI is poorly understood. The purpose of this study is to identify SLI genetic loci through family-based linkage mapping. Method: We performed genome-wide parametric linkage…

This study examined the linguistic dimensions of comprehensibility and perceived fluency in the context of L2 argumentative speech elicited from 40 Japanese-speaking learners of English. Their speaking performance was judged by 10 inexperienced native speakers of English for comprehensibility and perceived fluency, and was also objectively…

Purpose: The study was aimed at investigating what kind of lip positions are selected by Japanese adult participants for an unfamiliar Mandarin rounded vowel /y/ and if their lip positions are related to and/or differentiated from those for their native vowels. Method: Videotaping and post hoc tracking measurements for lip positions, namely…

Across languages, certain syllable types are systematically preferred to others (e.g., "blif" ? "bnif" ? "bdif" ? "lbif" where ? indicates a preference). Previous research has shown that these preferences are active in the brains of individual speakers, they are evident even when none of these syllable types…

This longitudinal study assessed three acoustic components of maternal infant-directed speech (IDS) -- pitch, affect, and vowel hyperarticulation -- in relation to infants' age and their expressive vocabulary size. These three individual components were measured in IDS addressed to infants at 7, 9, 11, 15, and 19 months (N = 18). All three…
