In the first year of life, infants' speech perception becomes attuned to the sounds of their native language. This process of early phonetic learning has traditionally been framed as phonetic category acquisition. However, recent studies have hypothesized that the attunement may instead reflect a perceptual space learning process that does not…

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…

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…

The Hindi consonant inventory, which includes the cross-linguistically rare retroflex place of articulation and four-way laryngeal contrasts, is known to pose difficulties for native English speakers. Hindi language textbooks address this challenge, in part, by providing various articulatory and acoustic descriptions of Hindi consonants, typically…

The extant studies addressing second language phonetic perception assume that second language phonemes are perceived to be similar to first language phonemes, and tend to be substituted by learners of English as a foreign language. This study aimed to assess the perceptual relationship between the phonemes of English and the sound units of Omani…

This research investigated whether observing beat gesture and hearing contrastive accenting with novel words enhances their learning in early childhood and whether these effects differ by sex in light of sex differences in the pace of language development. Fifty-three 3- to 5-year-old boys and girls learned pairs of novel words with contrasting…

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…

Upon acquiring or learning another language, cross-linguistic influence (CLI) is an inevitable phenomenon with which a bilingual speaker lives. One key aspect of CLI is its bidirectionality, flowing between both the first (L1) and second languages (L2) mutually affecting each other. However, investigations of L1 CLI on L2 have dominated previous…

Prior research has extensively explored audiovisual speech perception and literacy skills in various linguistic contexts. Studies have shown that children's ability to integrate auditory and visual speech cues plays a crucial role in language acquisition and development (Erdener & Burnham, 2013; Lalonde & Werner, 2021). Furthermore,…

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/…

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 dissertation examines the development of the internal structure of the Korean syllable by adult Korean learners whose native language is English. Prior research has identified the prominence of the body constituent in Korean and the rime constituent in English. The current study focuses on the acquisition of the body unit by English speakers…

This article reports on the second language (L2) perception of contrasts among British English monophthongs. This study has two aims: 1) to explore the discriminability of contrasts in L2 British English monophthongs; and 2) to test the perceptual assimilation model-L2 (PAM-L2) towards the ability to discriminate British English contrasts. The…

Mandarin speakers tend to adapt intervocalic nasals as either an onset of the following syllable (e.g. Bruno [right arrow] "bù.lu.nuò"), as a nasal geminate (e.g. Daniel [right arrow] "dan.ní.er"), or as one of the above forms (e.g. Tiffany [right arrow] "dì.fú.ní" or "dì.fen.ní"). Huang and Lin (2013, 2016)…

The research reported in this article investigated how students learning Japanese or Russian as a third language (L3) perceived and produced word-initial stops in their respective target language and the link between perception and production. The participants in the study were 39 Chinese university students who spoke Mandarin Chinese as their…
