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…

Second language (L2) learners often have difficulty perceiving L2 sound contrasts when the first-language (L1) and L2 sounds are acoustically similar and these similar L2 sounds correspond to an existing L1 sound (Flege, 1995). To improve L2 learners' perception of sound contrasts, researchers have used high-variability phonetic training (HVPT)…

The present study investigated the effect of emotional valence on auditory word recognition memory in English as a foreign language. Participants included 48 native Spanish speakers whose foreign language was English. They viewed four emotionally negative, four positive, and four neutral videos that, in total, contained 48 emotionally valenced…

Arabic emphasis refers to the production of consonants resulting from a primary constriction in the dental or alveolar region and a secondary constriction in the back of the vocal tract, recognized as 'Emphatic.' These have contrastive consonants produced in the dental or alveolar region, recognized as 'Plain.' The existing research on emphasis in…

Many studies evidence the flexibility of speech perception in the first language (L1), which allows rapid adaptation to unfamiliar foreign accents. Two influential studies by Bradlow and Bent (2008) and a follow-up study by Baese-Berk et al. (2013) found that increased variability as a function of the number of talkers and accents facilitated the…

This article reviews research findings involving visual input in speech processing in the form of facial cues and co-speech gestures for second-language (L2) learners, and provides pedagogical implications for the teaching of listening and speaking. It traces the foundations of auditory-visual speech research and explores the role of a speaker's…

We provide an exhaustive review of studies in the relatively new domain of research on the influence of orthography on second language (L2) phonological acquisition. While language teachers have long recognized the importance of written input--in addition to spoken input--on learners' development, until this century there was very little…

This study tested the effect of constraining sentence context on word recognition time (RT) in the first and second language. Native (L1) and nonnative (L2) speakers of English performed self-paced reading and listening tasks to see whether a semantically-rich preceding context would lead to the activation of a probable upcoming word prior to…

Successful listening in a second language (L2) involves learning to identify the relevant acoustic-phonetic dimensions that differentiate between words in the L2, and then use these cues to access lexical representations during real-time comprehension. This is a particularly challenging goal to achieve when the relevant acoustic-phonetic…

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…

Teachers' understanding of the process of speech perception could inform practice in listening classrooms. Catford (1950) developed a model for speech perception taking into account the influence of the acoustic features of the linguistic forms used by the speaker, whereby the listener "identifies" and "interprets" these…

This study aimed to investigate the effect of written cues on the second- language (L2) language perception, processing, and word learning, especially when the person's first language (L1) belongs to a different rhythmic type of language than L2. The first objective was to examine whether late bilinguals as L2 learners can benefit more from…

Speech production and perception are inextricably linked systems. Speakers modify their speech in response to listener characteristics, such as age, hearing ability, and language background. Listener-oriented modifications in speech production, commonly referred to as clear speech, have also been found to affect speech perception by enhancing…

Bilingual speakers must acquire the phonemic inventory of 2 languages and need to recognize spoken words cross-linguistically; a demanding job potentially made even more difficult due to dialectal variation, an intrinsic property of speech. The present work examines how bilinguals perceive second language (L2) accented speech and where…

How are languages learned, and to what extent are learning mechanisms similar in infant native-language (L1) and adult second-language (L2) acquisition? In terms of vocabulary acquisition, we know from the infant literature that the ability to discriminate similar-sounding words at a particular age does not guarantee successful word-meaning…
