Purpose: This study investigates whether crosslinguistic effects on auditory word recognition are modulated by the quality of the auditory signal (clear and noisy). Method: In an online experiment, a group of Spanish--English bilingual listeners performed an auditory lexical decision task, in their second language, English. Words and pseudowords…

Purpose: The goal of this study was to develop and validate a new corpus of sentences without semantic context to facilitate research aimed at isolating the effects of semantic context in speech perception. Method: The newly developed corpus contains nonsensical sentences but is matched in vocabulary and syntactic structure to the existing Basic…

Korean learners of English are known to repair consonant clusters, which are not allowed in their native language, with an epenthetic vowel [close central unrounded vowel]. The purpose of the present study is to examine whether the perception-production link of such an illusory vowel in a second language (L2) is only within and not across…

Adult second language learners often show considerable individual variability in the ease with which lexical tones are learned. It is known that factors pertaining to a learner's first language (L1; such as L1 tonal status or L1 tone type) as well as extralinguistic factors (such as musical experience and working memory) modulate tone learning…

Upon hearing someone's speech, a listener can access information such as the speaker's age, gender identity, socioeconomic status, and their linguistic background. However, an open question is whether living in different locales modulates how listeners use these factors to assess speakers' speech. Here, an audio-visual test was used to measure…

Feature-based approaches to acquisition principally focus on second language (L2) learners' ability to perceive non-native consonants when the features required are either contrastively present or entirely absent from the first language (L1) grammar. As features may function contrastively or allophonically in the consonant and/or vowel systems of…

We studied English-learning children's ability to learn the meanings of novel words from sentences containing truth-functional negation (Exp1) and to use the semantics of negation to inform word meaning (Exp2). In Exp1, 22-month-olds (n = 21) heard dialogues introducing a novel verb in either negative-transitive "("Mary didn't blick the…

Previous studies have shown that Chinese speakers and non-Chinese speakers exhibit different patterns of cross-modal congruence for the lexical tones of Mandarin Chinese, depending on which features of the pitch they attend to. But is this pattern of language-specific listening a conscious cultural strategy or an automatic processing effect? If…

Purpose: The aim of this study is to investigate whether human auditory frequency tuning can be influenced by tonal language experience. Method: Perceptual tuning measured via psychophysical tuning curves and cochlear tuning derived via stimulus-frequency otoacoustic emission suppression tuning curves in 14 native speakers of a tonal language…

Understanding speech in adverse conditions is affected by experience--a familiar voice is substantially more intelligible than an unfamiliar voice when competing speech is present, even if the content of the speech (the words) are controlled. This familiar-voice benefit is observed consistently, but its underpinnings are unclear: Do familiar…

English has become an international language (EIL) as speakers around the world use it as a universal means of communication. Accordingly, scholars have investigated different aspects of EIL affecting communicative success. Speech scholars have been interested in speech constructs like accentedness, comprehensibility, and acceptability (e.g., Kang…

Purpose: The purpose of this study was to examine whether oral bilingualism could be an advantage for children with hearing loss when learning new words. Method: Twenty monolingual and 13 bilingual children with hearing loss were compared with each other and with 20 monolingual and 20 bilingual children with normal hearing on receptive vocabulary…

Although extensive research has focused on the perceptual abilities of second language (L2) learners, a significant gap persists in understanding how cognitive functions like phonological short-term memory (PSTM) and nonverbal intelligence (IQ) impact L2 speech perception. This study sets out to investigate the discrimination of L2 English…

This study investigates the perception of the three Mandarin high vowels /i, u, y/ after dental, retroflex, and palatal fricatives and affricates (/s/-/[voiceless alveolar affricate]/-/[voiceless alveolar affricate][superscript voiceless glottal fricative]/; /[voiceless retroflex sibilant fricative]/-/[voiceless alveolar affricate]/-/[voiceless…

Purpose: Children with hearing loss (HL), including those with hearing aids (HAs) and cochlear implants (CIs), often have difficulties contrasting words like "beach" versus "peach" and "dog" versus "dock" due to challenges producing systematic voicing contrasts. Even when acoustic contrasts are present,…
