Research on the acoustic characteristics of Infant Directed Speech (IDS) in North American English indicates that it is generally higher-pitched than Adult Directed Speech (ADS) and has unique prosodic characteristics, which is commonly found across many spoken languages. However, very little research has addressed another important aspect of…

Purpose: Extemporaneous speech tasks provide an ecologically valid sample to examine speech acoustics, but differing methodologies exist in the literature for segmentation. Therefore, the purpose of this study was to examine the utility and reliability of a segmentation approach for extemporaneous speech specified by systemic functional…

Speech is highly variable and systematic, governed by the internal linguistic system and socio-indexical factors. The systematic relationship of socio-indexical factors and variable phonetic forms, referred to here as "socio-indexical structure," has been the cornerstone of sociophonetic research over the last several decades. Research…

With the rise of different English varieties, scholars argued for reconceptualizing teaching pedagogies to acknowledge and incorporate diverse Global English (GE) varieties into the classroom (Rose & Galloway, 2019). However, very few studies explored the effectiveness of such innovative pedagogy on language skills. This study investigated the…

Despite the fact that pronunciation is a vital aspect of language learning, previous research has shown that its instruction is limited in the classroom in terms of time and attention, due in part to the time constraints inherent in any curriculum. It then becomes essential for instructors to be strategic about the pronunciation features they…

This paper examines links between perfect rhymes and text readability and decoding using a measure of English rhymes called the Perfect Rhymes Dictionary (PeRDict). PeRDict is based on the Carnegie Mellon University Pronouncing Dictionary (the CMUdict) and provides rhyme counts for ~48,000 words in English and for the most frequent 1,000, 2,500,…

Purpose: The aim of this study was to compare word-initial and word-final consonant cluster productions in young children who speak African American English (AAE) and compare their productions to what we know about cluster productions in children who speak Mainstream American English (MAE), in order to minimize misdiagnosis of speech sound…

Purpose: The purpose of this study was to examine the differences between the age of acquisition (AoA) and sentence length of sentences of the speech recognition (SR) tests for adults and children in Dutch, American English, and Canadian French. Method: The AoA and sentence length of the sentences of four SR tests for adults and children were…

Background: Developmental dysarthria is a motor speech impairment commonly characterized by varying levels of reduced speech intelligibility. The relationship between intelligibility deficits and acoustic vowel space among these individuals has long been noted in the literature, with evidence of vowel centralization (e.g., in English and…

Background: Bilingual speech production studies have highlighted that level of proficiency influences the acoustic-phonetic representation of phonemes in both languages (MacKay, Flege, Piske, & Schirru 2001; Zarate-Sandez, 2015). The results for bilingual speech production reveals that proficient/early bilinguals produce distinct acoustic…

Purpose: The goal of this study was to investigate vowel detection and identification in noise and provide baseline data regarding how vowel perception changed with signal-to-noise ratios. Psychometric functions of vowel detection and identification for 12 American English isolated vowels in long-term speech-shaped noise were examined for young…

Our motivation was to examine how toddler (2;6) and adult speakers of American English prosodically realize information status categories. The aims were three-fold: (1) to analyze how adults phonologically make information status distinctions; (2) to examine how these same categories are signaled in toddlers' spontaneous speech; and (3) to analyze…

This corpus-driven study explores the linguistics phenomenon of mental verbs in English song lyrics from 1960s until 2000s. This study aims to identify the frequency distributions of lexical verbs, mental verbs, and to analyze the language uses of mental verbs in the Diachronic Corpus of English Song Lyrics (DCOESL). Quantitative and qualitative…

This study investigated the extent to which racialisation shapes EFL learners' conceptualizations of the 'native speaker' construct through an experimental design. Three hundred and fourteen university students studying at English-medium universities in Turkey were invited to take an online matched guise test. They were assigned to either the…

Purpose: This article compares acoustic data of normally developing children from two dominant and one nondominant variety of English in order to determine phonetic proximity. Method: The study focuses on one variety of American English (AE), one British English (BE) variety, and one Jamaican English (JE) variety owing to the historical and…
