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…

Recent work has shown significant sublexical effects of long-term memory in nonword repetition (NWR) using a dichotomous consonant age of acquisition (CAoA) variable (Moore, 2018; Moore, Fiez, and Tompkins, 2017). Performance consistently decreased when stimuli comprised consonants acquired later versus earlier in speech development. To address…

This study compared individuals from two first language (L1) backgrounds (Italian, Mandarin) to determine how they may differ in their perception of Japanese consonant length (i.e. singleton vs. geminate) according to the phonemic status of length in L1 and experience with Japanese. The participants included two groups of non-native learners of…

The extent to which exposure to new phonemic contrasts (i.e. contrasts that are present in the L2 but not in the L1) will lead to the creation of a new phonemic category in L2 speakers, as well as the phonological nature of these categories, remains an open question insofar as there is no consensus on whether acquiring a new contrast would result…

This study reports syllable position effects on second language (L2) Portuguese speech perception, revealing that L2 segmental learning may be prone to an influence from the suprasegmental level. The results show that first language (L1) Mandarin learners had diminished performance on the discrimination between the target Portuguese liquids (/l/…

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…

In dialogue, speakers tend to adapt their speech to the speech of their interlocutor. Adapting speech production to preceding speech input may be particularly relevant for second language (L2) speakers interacting with native (L1) speakers, as adaptation may facilitate L2 learning. Here we asked whether Dutch-English bilinguals adapt pronunciation…

The present study investigated whether the ability to encode the sounds of difficult second-language (L2) contrasts into novel nonnative lexical representations is modulated by the phonological form of the words to be learned. In 3 experiments, German learners of English were trained on word-picture associations with either novel minimal pairs…

Purpose: Most research examining long-term-memory effects on nonword repetition (NWR) has focused on lexical-level variables. Phoneme-level variables have received little attention, although there are reasons to expect significant sublexical effects in NWR. To further understand the underlying processes of NWR, this study examined effects of…

Spanish native speakers are known to pronounce onset /sC/ clusters in English with a prothetic vowel, as in "esport" for sport, due to their native language phonotactic constraints. We assessed whether accurate production of e.g. "spi" instead of "espi" was related to accurate perceptual discrimination of this…

In English as a Foreign Language (EFL) situations, it is important for educators to improve learners' sound recognition skill due to the variation of English found in the world. Furthermore, perceptual skill is a foundation leading to intelligibility in production. This study examined the effects of using High Variability Phonetic Training (HVPT)…

The purpose of this article is to report results of an investigation into the production of a covert contrast by native speakers of Korean, Portuguese, and Spanish in the acquisition of the English distinction between the high front vowels /i/ and /?/. A covert contrast is a statistically reliable acoustic distinction made by a language learner…

Perceptual assimilation is a well-known task; however, there is no study on the assimilation pattern of the English monophthongs by L2 Thai learners. The aims of this study are to explore the perceptual assimilation patterns of the British English monophthongs to Thai monophthongs by L2 Thai learners and to examine the effect of L2 experience on…

Studies of the acquisition of the lenited allophones of Spanish voiced stops have traditionally focused on the production (Lord, 2010; Rogers & Alvord, 2014; Zampini, 1994), but not on the perception of these sounds. This pilot study examines relationships between (a) learner proficiency and perception of target sounds; (b) learner perception…

This study investigated the role of syllable structure in L2 auditory word learning. Based on research on cross-linguistic variation of speech perception and lexical memory, it was hypothesized that Japanese L1 learners of English would learn English words with an open-syllable structure without consonant clusters better than words with a…
