Phonetic imitation is a ubiquitous process in speech production. Speakers have a strong tendency to imitate their interlocutors both in a native and a non-native language. It is especially important in acquiring non-native speech, because it allows forming new sound categories. In the current study we investigated whether and to what extent Polish…

Rhythm metrics can detect second language development of target-like speech rhythm but interpretation of the results from metrics in learners' speech is problematic because the mapping of metrics to underpinning phonological features is indirect. We investigate speech rhythm in first language (L1) Arabic / second language (L2) English, which…

Purpose: This study investigated the efficacy of ultrasound biofeedback compared to a traditional acoustic input-only method in the second-language (L2) production training of English tense-lax vowel contrasts (/i-[near-close near-front unrounded vowel]/ and /e-[open-mid front unrounded vowel]/). The relationship between the degrees of production…

This study examined how Korean EFL learners in different proficiency levels attest contrasts of L2 phonology. To this end, twenty Korean EFL learners in high and low levels of English proficiency produced words with word-final contrasts of /[esh]/ vs. /[esh]i/, /t[esh]/ vs. /t[esh]i/, and /d[ezh]/ vs. /d[ezh]i/. Acoustic analyses of lexical vs.…

This study investigates the acoustic realizations of English phonemic contrasts by Korean EFL learners, comparing their productions with those of native English speakers. Focusing on the segmentally correct production, the research aims to determine if Korean learners' acoustic properties align with those of native speakers, influenced by second…

Languages differ in the importance of acoustic dimensions for speech categorization. This poses a potential challenge for second language (L2) learners, and the extent to which adult L2 learners can acquire new perceptual strategies for speech categorization remains unclear. This study investigated the effects of extensive English L2 immersion on…

This study aims to understand if Mandarin late learners of English can successfully manipulate acoustic and kinematic cues to deliver English stress contrast in production. Mandarin (N = 8) and English (N = 8) speakers were recorded producing English trochaic (initial stress) and iambic (final stress) items during a nonword repetition task.…

This article revisits Lee and Mok (2018) and examines how the Cantonese learners in the study produced second language (L2) Japanese short vs. long consonants which are absent in their first language (L1). Specifically, our goal is to find out whether these learners were substituting real geminates (i.e. long consonants) with the improvised…

This study is a case study of the effects of tonal L1 on the acquisition of tonal L2, comparing two groups of tonal L1 learners, namely, Chinese Zhuang (C+Z) and Chinese non-Zhuang (C-Z) in the same classroom. The two groups of learners read aloud 60 words from a Thai wordlist, then their tone production was analyzed in two dimensions. The…

This paper critically analyses the meaning and use of translanguaging as an inclusive pedagogical strategy in the context of a bilingual deaf education classroom where there are asymmetrical sensorial experiences of being deaf and being hearing, and different access to 'codified' (either speech or sign-language) resources. The pedagogical…

This article provides a review of previous studies that have examined the effects of orthography on establishing contrastive phonological representations in second language acquisition and presents results from an original study on Mandarin speakers' production of English stops investigating how the presence of orthography affects the production…

Second language (L2) learners often speak with a strong accent, which can make them difficult to understand. However, familiarity with an accent enhances intelligibility. We propose that L2 learners are even more familiar with their own accented speech patterns and may thus understand self-produced L2 words better than others' accented…

Purpose: Although acquisition of Chinese lexical tones by second language (L2) learners has been intensively investigated, very few studies focused on categorical perception (CP) of lexical tones by highly proficient L2 learners. This study was designed to address this issue with behavioral and electrophysiological measures. Method: Behavioral…

This paper presents the results of a brief mixed-methods intervention which sought to modify the production of prominence-related features in L2 English by four native French-speaking university lecturers, in read-aloud speech. Selected parts of participants' productions were acoustically modified and then used as the model in a Listen-and-Repeat…

This study aims to investigate English as a foreign language (EFL) learners' use of context information under various noise conditions. The participants were seven Japanese undergraduate students. A noise test adopted from the Speech-Perception-in-Noise (SPIN) test (Kalikow et al., 1977) was used. Four signal-to-noise ratio (SNR) conditions (SNR =…
