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…

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…

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…

This study examined how discriminability and prototypicality of nonnative phones modulate the amplitude of the Mismatch Negativity (MMN) event-related brain potential. We hypothesized that if a frequently occurring (standard) stimulus is not prototypical to a listener, a weaker predictive memory trace will be formed and a smaller MMN will be…

Purpose: We examined how consonant perception is affected by a preceding speech carrier simulated in the same or a different room, for different classes of consonants. Carrier room, carrier length, and carrier length/target room uncertainty were manipulated. A phonetic feature analysis tested which phonetic categories are influenced by the…

Children are adept at learning their language's speech-sound categories, but just how these categories function in their developing lexicon has not been mapped out in detail. Here, we addressed whether, in a language-guided looking procedure, 2-year-olds would respond to a mispronunciation of the voicing of the initial consonant of a newly learned…

The present dissertation explores the effect of exposure to non-native speech via foreign film on non-native speech production and perception. In order to explore potential effects, two main experiments were developed, which examined French production and perception by monolingual native speakers of English before and after exposure to French…

Statistical learning has been proposed to underlie the developmental transition during infancy from allophonic to phonemic speech sound perception. Based on this, it can be hypothesized that in dyslexic individuals, core phonemic representation deficits arise from reduced sensitivity to the statistical distribution of sounds. This study aims to…

Every language has unique phonotactics, general rules about how phonemes combine to make syllables. We know that people can implicitly learn new phonotactic rules in the laboratory, and these rules then affect their speech errors. Some types of rules, however, require a consolidation period before they influence speech errors. Two experiments are…

Purpose: As a class, fricatives are more "resistant" to consonant-vowel coarticulation than other English sounds. This study investigates the relative coarticulatory resistance of /[voiceless dental fricative], s, [voiceless palato-alveolar fricative]/ in child and adult speech to better understand the acquisition of individuated speech…

The problem of cognitive overload is particularly pertinent in multimedia L2 classroom corrective feedback (CF), which involves rich communicative tools to help the class to notice the mismatch between the target input and learners' pronunciation. Based on multimedia design principles, this study developed a new multimodal CF model through…

Purpose: This clinical focus article provides readers with a description of the stimulus characteristics of 12 popular tests of speech sound production. Method: Using significance testing and descriptive analyses, stimulus items were compared in terms of the number of opportunities for production of all consonant singletons, clusters, and rhotic…

There is evidence that orthographic knowledge can influence on-line spoken-word recognition. Interestingly, when graphic and phonetic codes are not congruent due to the application of phonological alternation processes, people report hearing sounds that are matched to graphic (underlying), not phonetic codes (Hallé et al. in J Mem Lang 43:618-639,…
