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…

This study investigates acoustically one of long-term debated phonetic characteristics, the so-called Arabic voiced pharyngeal fricative /[voiced pharyngeal fricative]/. Most recent studies have found the Arabic pharyngeal to be approximant, while others have categorized it as a stop in careful speech, and still others have suggested it is a…

This study examined distributional statistical learning of positional, phonetic, and semantic regularities of an artificial orthography in Chinese children aged 8-10 years: 29 with dyslexia, 29 age-matched controls, and 30 reading-level matched controls. Despite having positional regularity learning performance comparable to the controls, the…

Purpose: We evaluated whether children whose inaccurate /[voiced alveolar approximant]/ productions showed evidence phonetic differentiation with /w/ at 3.5-4.5 years of age improved in /[voiced alveolar approximant]/ production over the next year more than children whose inaccurate productions did not show evidence of such differentiation. We…

There is a scarcity of research into the relationship between speech perception and production from a multilingual perspective. The present exploratory study investigates longitudinally the acquisition of rhotic sounds in 24 adolescent learners who have the same language repertoires (English, German, Polish), with English being their L2, and…

The research includes three studies at the intersection of communications disorders and computational linguistics. We begin with the case study of APTgt, a system created to improve reinforcement for Phonetics students and improve Linguistic tools for their instructions. A portion of this system utilizes machine learning techniques (i.e.,…

This study investigated the potential of phonetic symbols and keywords as response labels for perceptual training of L2 sounds. Seventy-one Spanish learners of English were assigned to three groups: symbols, keywords, and control. Students in the symbols and keywords groups followed a 4-week High Variability Phonetic Training (HVPT) program based…

Listeners selectively tune in to the most relevant cues for contrasting sounds, and this process impacts their perceptual sensitivity to these cues (Nosofsky, 1986; Pisoni, 1991). For bilingual listeners, recent work suggests a shared L1/L2 phonology system with the phonetic properties of each sound established in a language-specific way…

This study examined how Korean EFL learners in different proficiency levels attest contrasts of L2 phonology. To this end, twenty Korean EFL learners in high and low levels of English proficiency produced words with word-final contrasts of /[esh]/ vs. /[esh]i/, /t[esh]/ vs. /t[esh]i/, and /d[ezh]/ vs. /d[ezh]i/. Acoustic analyses of lexical vs.…

Pronouncing English clusters may be challenging for Arab English learners. Technology-based strategies can be used to improve their pronunciation of English consonant clusters. This study examined how high variability phonetic training (HVPT) can be used to improve the pronunciation of consonant clusters among English as a foreign language (EFL)…

Dutch and German employ voicing contrasts, but Dutch lacks the 'voiced' dorsal plosive /g/. We exploited this accidental phonological gap, measuring the presence of prevoicing and voice onset time durations during speech production to determine (1) whether preliterate bilingual Dutch-German and monolingual Dutch-speaking children aged 3;6-6;0…

Purpose: To better understand the role of tongue visibility in speech, this study compared the spatiotemporal patterns of silent versus audible speech for lingual consonants of American English. Kinematic data were obtained for articulatory features assumed to be visually salient, including tongue movement (anterior displacement and midsagittal…

Persuasiveness in oral communication in English can be expressed with various vocal phonetic cues that may not be readily accessible to English second language (L2) learners whose native language may employ a different set of cues. With a goal to increase L2 learners' perceived spoken confidence and persuasiveness, and obtain empirical evidence…

This study explores the second language (L2) acquisition of a segment that exists in learners' first language (L1) and in their L2 but that differs in its phonetic realization and allophonic patterning in the two languages. Specifically, this research tracks development in one aspect of the production of the alveolar lateral /l/ in the L2 Spanish…

Two acoustic studies of voice onset time (VOT) in sibilant-stop (ST) consonant clusters, produced by first language (L1) speakers of Polish, are presented. In the first, a baseline study of L1 Polish comparing ST clusters with initial singleton stops, a small degree of VOT shortening after /s/ was found for /p/, but not /t/. The second study…
